    Does technological progress automatically translate into higher wages, better standards of living, and widely shared prosperity? Or is it necessary to steer the development of technological improvement to ensure the benefits don't accrue only to the few? In a new book, two well-known economists argue the latter. I'm joined in this episode by one of the authors, Simon Johnson.Simon is the Kurtz Professor of Entrepreneurship at MIT. He and Daron Acemoglu are authors of the new book Power and Progress: Our Thousand-Year Struggle Over Technology and Prosperity. Simon is also co-author with Jonathan Gruber of 2019's Jump-Starting America, now out in a new paperback.In This Episode* Is America too optimistic about technology? (1:24)* Ensuring progress is widely shared (11:10)* What about Big Tech? (15:22)* Can we really nudge transformational technology? (19:54)* Evaluating the Biden administration’s science policy (24:14)Below is an edited transcript of our conversationIs America too optimistic about technology? James Pethokoukis: Let me start with a sentence or two from the prologue: “People understand that not everything promised by Bill Gates, Elon Musk, or even Steve Jobs will likely come to pass. But, as a world, we have become infused by their techno-optimism. Everyone everywhere should innovate as much as they can, figure out what works, and iron out the rough edges later.” Later, you write that that we are living in a “blindly optimistic” age.But rather, I see a lot of pessimism about AI. A very high percentage of people want an AI pause. People are very down on the concept of autonomous driving. They're very worried that these new technologies will only make climate change worse. We don't seem techno-optimistic to me. we certainly don't see it in our media. First of all, let me start out with, why do you think we're techno-optimistic right now, outside of Silicon Valley?Simon Johnson: Well, Silicon Valley is a very influential culture, as you know, nationally and internationally. So I think there's a deep-running techno-optimistic trend, Jim. But I also think you put your finger on something very important, which is since we finished the book and turned in the final version in November, I think the advance of ChatGPT and some of our increased awareness that this is not science fiction — this is actual, this is real, and the people who are developing this stuff have no idea how it works, for example—I wouldn't call it pessimism, but I think there's a moment of hesitation and concern. So good, let's have the discussion now about what we're inventing, and why, and could we put it on a better path?When I think about the past periods where it seemed like there was a lot of tech progress that was reflected in our economic statistics, whether it's productivity growth or economic growth more broadly, those were also periods where we saw very rapid wage growth people think very fondly about. I would love to have a repeat of 1995-2000. If we had technologies that could manage that kind of impact on the economy, what would be the downside? It seems like that would be great.I would love a repeat of the Henry Ford experience, actually, Jim. Henry Ford, as you know, automated the manufacturing of cars. We went from producing tens of thousands of cars in the US to, 30 years later, producing millions of cars because of Ford's automation. But at the same time Ford and all the people around him — a lot of entrepreneurs, of course, working with Ford and rivals to Ford — they created a lot of new jobs, new tasks. And that's the key balance. When you automate, when you have a big phase of automation, and we did have another one during World War II and after World War II. We also created a lot of new tasks, new jobs. Demand for labor was very strong. And I think that it's that balance we need. A lot of the concerns, the justified concerns about AI you were mentioning a moment ago, are about losing jobs very quickly and faster than we can create other tasks, jobs, demand for labor in other, non-automating parts of the economy.Your book is a book of deep economic history. It's the kind of book I absolutely love. I wonder if you could just give us a bit of a flavor of the history of what's interesting in this book about those two subjects and how they interact.We tried to go back as far as possible in economic and human history, recorded history, to understand technological transformations. Big ones. And it turns out you can go back about 1000 years with quite reliable information. There are some things you can say about earlier periods, a little bit more speculative to be honest. But 1000 years is a very interesting time period, Jim, because as you know, that's pretty much the rise of Europe timeframe. A thousand years ago, Europe was a nothing place on the edge of a not very important part of one continent. And through a series of technological transformations, which took a long time to get going — and that's part of the medieval story that we explore — [there was] a huge amount of innovativeness in those societies. But it did not translate into shared prosperity, and it was a very stop-start. I'm talking about over the period of centuries.Then, eventually, we get this Industrial Revolution, which is initially in Britain, in England, but it's also shared fairly quickly around northwest Europe: individual entrepreneurship, private capital, private ownership, markets as a dominating part of how you organize that economy. And eventually, not immediately, but eventually that becomes the basis for shared prosperity. And of course, that becomes the basis for American society. And the Americans by the 1850s to 1880s, depending how you want to cut it, have actually figured out industrial technology and boosted the demand for labor more than the Europeans ever imagined. Then the Americans are in the lead, and we had a very good 20th century combining private capital, private innovation with some (I would say) selective public interventions where a private initiative didn't work. And this actually carried a lot of countries, including countries in that European tradition, through to around 1980. Since 1980, it's become much more bumpy. We've had a widening of income inequality and much more questioning of the economic and political model.Going back into the history: Oftentimes people treat the period before the steam engine and the loom as periods of no innovation. But there was. It just didn't have the impact, and it wasn't sustained. But we were doing things as a society before the Industrial Revolution. There was progress.There was technological progress, technological change. Absolutely.The compass, the printing press, gunpowder — these are advances.Right. The Europeans, of course, were sort of the magpies of the world at that point. A lot of those innovations began in China. Some of them began in the Arab world. But the Europeans got their hands on them and used them, sometimes for military purposes. They figured out civilian uses as well. But they were very innovative. Some people got rich in those societies, but only a very few people, mostly the kings and their hangers-on and the church. Broad-shared prosperity did not come through because it was mostly forced labor. People did not own their labor. There was some private property, but there wasn't individual rights of the kind that we regard as absolutely central to prosperity in the United States, because they are central to prosperity and because they're in the Constitution for a reason, because it was coming out of feudalism and the remains of that feudal system that our ancestors in the United States were escaping from. So they said, “Let's enumerate those rights and make sure we don't lose them.” That's coming out of 800 years of hard-learned history, I would say, at that point. And that's one reason why, not at the moment of independence but within 50 to 70 years, the American economy was really clicking and innovating and breaking through on multiple technologies and sharing prosperity in a way that nobody had ever seen before in the world.Before that period in the 1800s, the problem was not the occasional good idea that changed something or made somebody rich; it was having sustained progress, sustained prosperity that eventually spread out wide among the people.Absolutely. And I think it was a question of who benefited and who was empowered and who could go on and invent the next things. Joel Mokyr, who's an economic historian at Northwestern, one of our favorite authors, has written about the sort of revolution of tinkerers. And that's actually my family history. My family, as far back as we can go, was carpenters out of Chesterfield in the north of England. They made screws for a hundred years starting in the mid-19th century in Sheffield. They would employ a couple of people at any one time. Maybe no more than eight, maybe as few as two. They probably initially polished blades of knives and eventually ended up making specialized screws. But very, very small scale. There was not a lot of formal education in the family or among the workforce, but it was all kind of relationships with other manufacturers. It was being plugged into that community. Alfred Marshall talked about these clusters and cities of regional entrepreneurship. That's exactly where I'm from. So, yes, I think that was a really key breakthrough: having the institutions, the politics, and the social pressure that could sustain that kind of economic initiative.In the middle of the Industrial Revolution, late 1800s, what were the changes that we saw that made sure the gains from this economic progress were widely shared?If we're talking about the United States, of course, the key moment is the mechanization of agriculture, particularly across the West. So people left their farms in Nebraska or somewhere and moved to Chicago to work for McCormick, making the reapers that allowed more people to leave their farms. So you needed a couple of things in that. One was, of course, better sanitation and basic infrastructure in the big cities. Chicago grew from nothing to be one of the largest cities in the world in period of about a decade and a half. That requires infrastructure that comes from local government. And then there's the key piece, Jim, which is education. There was what's known as a “high school movement.” Again, very local. I don't think the national government knew much about it until it was upon them. [It was] pushing to educate more people in basic literacy and numeracy and to be better workers. At the same time, we did have from the national government, of course particularly in the context of the Civil War, the land grant universities, of which MIT is very proudly one of by the way — one of the only two that became private for various reasons. But we were initially founded to support the manufacturing arts in Massachusetts. That was a state initiative, but it was made possible by a funding arrangement, a land swap, actually, with the federal government.Ensuring progress is widely sharedThe kind of interventions which you've already mentioned — education and infrastructure — these seem like very non-controversial, public-good kinds of things. How do those kinds of interventions translate into the 2020s and 2030s in advanced countries, including the United States? Do we have need to do something different than those?Well, I think we should do those, particularly education, better and more and update it really quickly. I think people are going to agree on that in principle; there may be argument about how exactly you do that. I do think there are three things that should be on the table for potential serious discussion and even potential bipartisan agreement. The first is what Jaron Lanier calls “data dignity,” which is basically [that] you and I should own the data that we produce. This is an extension of private property rights from the right of the political spectrum. The left would probably have other terminology for it. But what's basically happening, and the value that's being created in these large language models, is those models are taking data that they find for free — actually, it's not really free, but it's not well protected on the internet, digital data — and they're using that to train these very large models. And it's that training process that's generating, already and will train even more, huge value and potential monopoly power for incumbents there. So Jaron’s point is, that's not right. Let's have a proper organization and recognition of proper rights, and you can pay for it. And then it also gives consumers the ability to bargain potentially with these large monopolies to get developers some technologies rather than other technologies.The second thing is surveillance. I think everyone on the right and the left should be very uncomfortable with where we are on surveillance, Jim, where we've slipped into already on surveillance, and also where AI is going to take us. Shoshana Zuboff has a great book, The Age of Surveillance Capitalism on exactly this, going through where we are in the workplace and where we are in in our society. And then of course there's China and what they're doing in terms of surveillance, which I'm sure we're not going to do. In fact, I think the next division of the world may be between the low-surveillance or safeguarded-surveillance places, which I hope will include the US, and the high-surveillance places, which will be pretty much authoritarian places, I would suggest. That's a really different approach to the technology of how you interact with workers, citizens, everybody in all their various roles in life.The third one we're probably not going to agree on right away, but I do want us to have some serious discussion about it, is corporate taxation. Kim Clausing from UCLA, a former senior Treasury person, points out that we do have a graduated corporate tax system in the US but bigger companies pay less. Smaller companies’ effective tax rate is higher than bigger companies because they move their profits around the globe. That's not fair and that's not right. And she proposes that we tax mega profits above $10 billion, for example, at a higher rate than we tax smaller profits to give the big companies that are very successful, very profitable an incentive to make themselves smaller. The reason I like Kim's proposal is I want competition, not just between companies directly in terms of what they're offering, but also between business models and mental models. And I think what we're getting too much from Microsoft and Google and the others who are likely to become the big players is machine intelligence, as they call it, which basically means replacing people as much as possible. We argue for machine usefulness, which is also, by the way, a strong tradition in computer science — it's not the ascendant tradition or ascendant idea right now — that is, focusing technology on making humans more effective. Like this Zoom call is making us more effective. We didn't have to get ourselves in the same room. We are able to leverage our time. We're able to organize our lives differently.Find those kinds of opportunities, particularly for lower-income workers. We are not getting that right now because we lack competition, I think, in the development of these models. Jim, too much. You joked at the beginning that the Silicon Valley is the only optimist. Maybe that's true, but they're the optimists that matter because they're the ones who control the development of the technology. Almost all those strings are in t…

    I have many times written about the importance of the story we tell ourselves about the future, especially in big-budget science fiction films. But does all the doom and gloom from Hollywood even matter? And is it driven from creatives at the top or by audience demand? To discuss those questions and more, I'm talking with Sonny Bunch.Sonny is the culture editor for The Bulwark, where he hosts The Bulwark Goes to Hollywood newsletter and podcast.In This Episode* Netflix’s upcoming $200 million techno-pocalyptic movie (1:06)* Why is Hollywood obsessed with dystopia? (6:17)* The solutionism of The Martian (8:48)* Do sci-fi visions of the future even matter? (15:03)Below is an edited transcript of our conversationNetflix’s upcoming $200 million techno-pocalyptic movieJames Pethokoukis: I write a lot about negative future-pessimistic media. Netflix has a big new movie in the works, a $200 million film directed by the Russo brothers, who you may know from the Marvel movies. They’ve got Millie Bobby Brown, Chris Pratt. Big production. It's called The Electric State. And this is a summary of this film: “A runaway teenager and her … robot travel west through a strange USA, where the ruins of gigantic battle drones litter the countryside heaped together with the discarded trash of a high tech consumerist society in decline.” And then it goes on about our “hollow core of civilization has finally caved in.”This might be a fantastic film, and I have a lot of confidence in the Russo Brothers and that budget. Here we are, we have a lot of interesting things cooking in the world from the Musk rockets and AI and huge breakthroughs in biotechnology, and that's the movie they're giving us for $200 million, about the decline of consumerist society. You've been writing a bit about this topic. When does it end?Sonny Bunch: It's interesting because I was thinking about this the other day: Really, what is the only truly utopian vision of the future? It's Star Trek. That's about it. In terms of mass popular entertainment, the only really, truly utopian ideal of the future is Star Trek. Now, there's still conflict in Star Trek. But it is at least a kind of post-scarcity society where folks are interested in exploring the world and bettering everyone. Look, part of this is it is easier to create tension and drama out of things that are bad. And what's the easiest way to look at how things might be bad? Look at what basically works about right now and say, “Well, what if this doesn't work? What if it's actually bad for us?” The idea of Netflix producing a stirring condemnation of consumerist society is kind of funny in and of itself. Netflix is the absolute peak of consumerism.Literally, the mission statement of Netflix is to sit on your couch and consume; consume so much you don't fall asleep. The initial argument for Netflix one of the creators the company made was, “We are trying to win the war against sleep.” They're not winning the war against sleep by encouraging people to create wonderful new advancements of society. It’s just to sit there and passively consume. So it's kind of funny. I like a good dystopian action movie. I can watch those all day long, so I'm probably as much of the problem as anything else. But it's definitely a thing.And it just doesn't seem that hard to me to have some sort of positive message, even if it's overall kind of dystopian or apocalyptic. I just don't see that there's any attempt. It's just full-throated doom.Remember when Interstellar came out? I love Interstellar. Great movie. It is hopeful in a certain way. It's about trying to find new places for Earth to live; it's on the edge of collapse. When Matthew McConaughey's character comes back about a hundred years later because of all the time dilation, humanity has moved up to the space stations that are orbiting and people have been saved. As far as these things go, it's actually a fairly positive message. Except there was an undercurrent from some critics who were like, “You know, this means that like billions of people died, right? They didn't save more than a handful of folks up on those space stations. Most of humanity is dead or dying.” And I was like, yeah, but they didn't focus on that. It's still pretty positive.I would counter argue that one of the themes of that movie is at some point we turned our back on progress. It's like society be has become anti-technology. To me, that movie says if we had not abandoned technological progress, maybe this huge disaster which has befallen the Earth, maybe we could have fixed it. But now it's too late. Now we have no other choice but to head to the stars, which is something we probably should have been thinking about anyways. I think a superficial viewing of that movie is that it is pessimistic. And I think you're right. I think, fundamentally, that is a future pro-progress film.Why is Hollywood obsessed with dystopia?But you mentioned Star Trek at the beginning. Why do you think Hollywood's sci-fi, at least, has become almost completely obsessed with the dystopian and apocalyptic? Is it just that it's easy to make that kind of film? Or is it reflecting something in our society?I don’t know. What do we like to say? Everybody likes to think they're living in the end times. Everybody likes to think that they are important enough to see the end of the world. This is a constant through human civilization. Everybody thinks that the end is just around the corner, and they're the last generation that will see the world. And now we have the technology and the filmmaking ability to actually realize that world we have; we have the ability to destroy the world on film. (In real life, too, if somebody really wanted to get crazy, but it's much easier and safer to do on film.) And it is easier. It's an easier story to tell. It's an easier story to portray because if you live in a post-apocalyptic society, there are a lot fewer of? Extras. You don't have to fill stadiums full of people. You don't have to have crowded streets with everybody walking around. You just have somebody, oh,You have empty streets and a little bit of trash, and you have a set.You’ve got empty streets. This is the Russo brothers. They're doing it all on green and blue screens. You’ve just got Millie Bobby Brown walking around, kicking over a trashcan every now and again, and it's fine. I do think that there's an inherent narcissism to all of this: We have achieved the peak of civilization. What's the line in The Matrix when Agent Smith is talking about how they designed the Matrix?We took the peak of civilization.We took the peak of human civilization, but really once we started thinking for you, it became our civilization. And what did they pick? They picked 1999, when that movie came out. That is the constant refrain in all of this stuff: We are the peak, things are to go precipitously downhill, enjoy it while it lasts. It is inherently dramatic, in a certain way, to imagine having to come back from a fall of a sort. But the fact that it is so constant just leads me to believe that it really is quite silly.The solutionism of The MartianYou mentioned Star Trek, but I would also say a movie like The Martian, which I also view as positive, pro-technology, pro-solutions — we can solve problems. And to me, that's what's wrong with a lot of these other films: we end up not being able to solve any problems. Probably our attempts to solve the problems only make things worse. And that is, to me, a rare example of a problem-solving movie that's plenty dramatic. There's no obvious villain, other than perhaps the planet Mars itself and space. To me, it's just a fundamental lack of effort. And again, I don't know if it's easy, it's cheaper in some ways, it also kind of reflects the views of the people who make the movies. But it's just shocking that there's not more made, because we do have a few examples of being able to do it properly.It is interesting. I wrote a piece for the Washington Post a few years back about how environmentalists make good movie villains. And the reason that they make good movie villains is because these are the people who the writers can really identify with. The whole idea of creating a realistic villain, if you want a realistic villain, is it's somebody you can identify with, somebody whose goals you sympathize with. And many of these villains — for instance Thanos in the first run of MCU movies, his whole thing is, “I lived through environmental collapse, many people died, it drove me insane, and I'm going to eliminate half of the universe so to avoid this problem again.” Which seems to defeat the purpose, but whatever. The reason he is sympathetic to the people who are writing these movies is that they look around and they see, “Global warming. It’s happening. It's here. We're all going die. There's going to be crop collapses. The population bomb is going off. We're never going to make it.” And nevermind that none of this has come to pass in the 50 to 100 to 1,000 years that we've been talking about it. It is still an ever-present terror. And if you're a person of a certain worldview, I can see why it would be appealing to try and work through it. The Martian is interesting, too, because The Martian is kind of techno-utopian in the sense that it posits a world in which all of the world's powers can work together. There's a very specific subplot with China—which at the time was doing more space shuttle, rocket exploration-type stuff than we were—working hand-in-hand with China to kind of make it all work out. I'm curious to see how that specific subplot would play today, if that is a thing that would be in the novel or the movie, or if it would not be.The relationship between the nations might have been portrayed a bit testier. That movie came out — the novel came out a bit earlier, but certainly the film came out just as things were starting to turn.Also, just in terms of the business of Hollywood, it's an interesting movie. Because that's a movie that came out right when Hollywood was really trying to make inroads into China, was working hand-in-hand with the Chinese government to get script approval and make sure that their films got a release there. And of course, it is impossible — this is the one thing I say over and over again to people — it is impossible to understand the artistry of Hollywood without understanding the business of Hollywood. You cannot understand why movies get made or how they get made or how they're received by Hollywood without understanding what is actually happening in the business of Hollywood. And at that moment in time, China was a market ripe for the plucking. Again, things have changed a bit in the last few years. I would be curious to see how that played now.If I were writing a script and I wanted it to have some sort of internal logic and I wrote that the driving force from my villain is that he needs to kill half of every living being in the universe so all of life doesn't consume all the resources, that idea would die immediately. If I brainstormed that idea, it wouldn't last 30 seconds. To me, it sort of gets at the ethos in Hollywood in which someone didn’t say, “We need to come up with a better motivation for the film, because that's ridiculous.”Two things here. One, it's very funny, the original comic book motivation — I'm going to put on my nerd hat here for a second — the original comic book motivation for Thanos actually weirdly makes more sense: He just wants to kill half the universe to please his girlfriend, death, the manifestation of death. That's what he wants to do. I actually find that to be much more sensible than what they wound up with. But the second thing is that this is my broad case for [why] Hollywood should hire more conservative screenwriters. Because if you really want your villains to be a villainous and for the industry to kind of reflect your own beliefs, you need like oil barons who aren't cartoonishly mustache-twirling. You need people who are out there like, “Yes, we're going to frack because that's what's going to power the hospital for the children. We're going to build nuclear power plants and we're going to dump the waste in this nature preserve because that's the only way to keep the bread factory running for the orphans.” Things like that.Do sci-fi visions of the future even matter?Does any of this matter? Does it matter how we portray the future? Does it matter how we portray—or perhaps in this case we don't really portray—innovators or explorers? Is this something that's just confined to our media consumption habits? Or does it have a bigger impact on the world? Obviously I think it does, but I'm open to someone arguing that it doesn't.I go back and forth on this question, honestly. I really go back and forth on this, because I do think there's a chicken and an egg issue here. I think that the art of a time reflects the sensibility of the time. I think that is mostly how the cause and effect works, but I also do think that a society chooses how to live by the stories they tell themselves in a very real way. I think this is why myth is important. This is why the stories we tell children matter. I do think that the art that we consume does help shape how we choose to live. I don't want to mush-mouth weasel my way out of this, but I do think it's a very open and interesting question. Depending on the day of the week, I can argue either side of it.I did an interview early on in my Substack with Ronald D. Moore, who has this great series For All Mankind. It shows a space race that never ends. It creates a really interesting alt-reality, that while there are still problems, we're better off for continuing to head into space. It doesn't seem that hard. I asked him some of the exact same questions I'm asking you. He was like, “It's economics. People think that makes money and until it stops making money, we're going to keep getting more of it.” I would like to think that there'd be something more to it than that, that film studios, if they have the opportunity to make something that can make money, but also doesn't completely reflect some sort of cultural exhaustion, that they would do it. But maybe I'm just too optimistic.This very much is my point with China: Everything that Hollywood makes is based on the last thing before that made money until none of that stuff is making money. And then they have to find something else. This is why you had a bunch of…You're still getting more zombie movies with The Last of Us. I thought that had just about died out.No, The Last of Us, huge hit. 30 million people watching on HBO across its various platforms. We're going to get more of The Last of Us, more zombies: The Walking Dead, 17 more spinoffs of that. We’ll see. This is a public episode.

    The conventional narrative about the economic history of World War II says that new learning from wartime mobilization jumpstarted a postwar golden age of fast economic growth. But, economist Alexander Field writes in his 2011 book, A Great Leap Forward, "It was not principally the war that laid the foundation for postwar prosperity. It was technological progress across a broad frontier of the American economy during the 1930s." Field develops that argument in his new book, The Economic Consequences of U.S. Mobilization for the Second World War, released last fall. In this episode of Faster, Please! — The Podcast, I'm joined by Alex to discuss his argument.Alex is the Michel and Mary Orradre Professor of Economics at Santa Clara University's Leavey School of Business.In This Episode* Depression-era technological progress* Economic detective work (8:04)* What about the scientific advances of WWII? (13:23)* The US economy if WWII never happened (17:39)Below is an edited transcript of our conversationDepression-era technological progressJames Pethokoukis: You write in A Great Leap Forward, a book that I consult frequently and mentionfrequently in my writings: “The years 1929-1941 were, in the aggregate, the most technologically progressive of any comparable period in U.S. economic history. … It was not principally the war that laid the foundation for postwar prosperity. It was technological progress across a broad frontier of the American economy during the 1930s.” Your new book builds upon that argument, but could you, just for a moment, give a quick summary of A Great Leap Forward, and then how that moves into your new book?Alexander Field: The basic argument of A Great Leap Forward was that behind the backdrop of double-digit unemployment for at least a decade, potential output was growing by leaps and bounds during the Great Depression. It wasn't really recognized until Simon Kuznets had to try to do a back-of-the-envelope calculation of what the potential of the economy could be. But the contributors to that were, I think, several. Number one was the last third of the conversion of the internal transmission of power within American factories from the shafts and belts, which was a signature of the 19th-century factory, to fractional-horsepower electric motors and electric wiring. And the second part was just an enormous amount, surprisingly, of research and development spending. Just astounding, if you think of the Depression as being so disastrous macroeconomically, but in terms of the number of people employed growing by leaps and bounds, number of labs established. And then finally, although it's widely accepted that the New Deal spending was too small in a Keynesian sense to immediately bring the economy out of the Depression, nevertheless, that spending on streets and highways and bridges and hydropower and so on had very strong positive supply-side effects. I think it's the combination of those three factors that I see as responsible for making potential output so much larger in 1941 than people thought it was.For the layman, your finding in that book, your thesis, is extraordinarily counterintuitive. You would never expect that underneath that sky-high unemployment number and the failing banks and the breadlines, there was this sort of innovative ferment happening and foundations laid for future progress. Similarly, to the extent that people would have an economic opinion about World War II, I would guess: 1) that it brought us out of the Great Depression, and 2) that it was a period of key advances, key technologies and the fact maybe we learned how to do things more efficiently during the war, whether it's build boats or what have you. Those two things are what played a huge role in postwar prosperity—I think that might be sort of the everyman way they would conceive of it. That is not exactly what you found.I think you've done a very good job characterizing what I see as the two key themes in the conventional wisdom about the Second World War. Basically, the argument that fiscal and monetary stimulus rapidly closed the output gap, the unemployment rate went from under 10 percent in ‘41 to unimaginably low, below 2 percent, in ‘43 and ’44. That's accepted and I'm not challenging that. But the second part of the conventional wisdom is what the economists call learning by doing: the emphasis on the decline in unit costs with accumulated output as a result of producing military durables. And the argument is exactly as you stated it. The argument is that learning spilled over into the postwar period and kind of underlined the supply side foundations for the golden age, which is ‘48 to ‘73. Now, my argument is different.I see the Second World War from a productivity history perspective as a detour. My argument is that the progress, the growth of potential output up through 1941, that's essentially most of the reason why the US stands astride the world economy in ’48, not what happened between ‘41 and ’48. It might have been different if the US had persisted in producing a hundred thousand piston-driven aircraft a year. But we didn't. We didn't produce piston-driven aircraft. Most of the products that we got very good at making, we stopped making them fairly soon after Victory over Japan Day. And I view most of that specific human capital as not really having a great deal of relevance after the war.As you mentioned, the things we got good at making were not just the instruments of war, but the instruments of war at a particular period. They were not going to be applicable to future conflicts, but they're also not applicable to a civilian economy that, once the war was over, began to expand very quickly. You mentioned the airplanes. I would also assume the kind of ship building that was done in the war was also not particularly applicable to the post-war era.That's right. That's exactly right. I see basically, the success of US industry under government leadership in producing the military ordinance that supplied our armies, as well as those of Britain and the Soviet Union, our allies, and so on — I see that basically as the application of technologies that had been honed in the ‘20s and particularly in the 1930s, producing automobiles and refrigerators, and applying that management experience to mass producing military durables, rather than the view that it was experience producing military durables that laid the foundations for the postwar period in terms of the supply side.Economic detective workI think people would think that we didn't need to look anymore at the Great Depression or World War II, that this is, they would say, settled science. We know exactly what happened and why it happened. Apparently the role of the World War II, what happened there, is not settled science. So what were people missing previously? What did you find that presents a different perspective?I think, as you say, it began with the findings about the Great Depression. I think what we're doing in the business of research, particularly academic research, is we're researching things: We're trying to find something new to say. But finding something new to say is only part of it; it also has to be something that actually might be true. And so it really it came out of really deep immersion in a variety of sources, both statistical and documentary: reading the minutes of the War Production Board, reading the minutes of the planning committee. And as this happened, a lot of preconceptions that I had about the war began to fall away. For example, the central empirical finding, surprising finding, in this book, or the argument, is that the productivity of American manufacturing—and it is within manufacturing that we would expect to see the effects of learning by doing—actually dropped dramatically between 1941 and 1945.And one of the things that I kind of picked up from this immersion in the sources was, rather than a view of American industry during the war as 24/7, 365 days a year, I get a picture of really profound production intermittency. In other words, essentially the need to shut down production lines, because it's a shortage economy. You've moved from a surplus economy to a shortage economy; sub-assemblies and raw materials and ultimately labor are being rationed. And if you can't get the heat exchanger you need, then the whole line is going to sit there. It's a very different view. And then you see this being said. In [War Production Board chairman Donald] Nelson's biography he talks about destroyer escorts: “Well, they were sitting there for six months because they couldn't get the part that they needed to complete it.” And those are kind of throwaway lines. They're there, but they’re not part of the kind of standard narrative; they're kind of overlooked as anomalies. And I don't want to get too Thomas Kuhn-ian about that, but if you start kind of pulling those anomalies together and assembling them and so on, then you get a different picture. And that's what I've tried to articulate in the book.I love your role as a kind of economic detective. It's not just about going to the BLS website and pulling up the data and then off you go. There's some real detective work as a historian, as much as an economist, going on here. It's really interesting thinking about the narrative because I think you're right that I picture December 7th, 1941, we head off to war and then it's all hands on deck, the production lines are never quiet, the steel mills are never cool, and it's all that way until August 1945. But perhaps now having gone through this pandemic, we're a little more aware of what happens when you have a shortage economy, which is what you found.Yeah, it's absolutely the case. I mean, ‘42 was absolutely a chaotic, terrible year. I would say there was no consensus in Washington that the United States was going to win the war, and it wasn't just the problems of suddenly having to produce a radically different set of products and making all this transition. The Japanese and the Germans weren't making it any easier for us, and I talk about that in the book as well. I think also vastly overlooked: I had absolutely no idea of the severity of what I call the rubber famine in the United States. When the Japanese overran Singapore in February ’42 and then rapidly shut off all of the exports, they cut off over 95 percent of the one strategic material in which the United States had effectively no domestic sourcing. And they were panicked, absolutely panicked about this, the Rubber Survey Committee. So that was another negative supply shock. And then the Germans were enormously successful in torpedoing what I call the tanker pipeline that was bringing petroleum and petroleum products from east Texas and Louisiana to the eastern seaboard. That's how it was moved and so forth. And between January and June of ‘42, they torpedoed 400 ships in the Atlantic and the Caribbean and just completely shut that down. And there were also serious consequences about that.What about the scientific advances of WWII?Was the war a time of great science productivity? Or is that also a detour toward science that was not as applicable to the postwar period, and we were not able to build on the gains and science of the ‘20s and ‘30s and so forth?The evidence is pretty clear, and I would cite James Conant, former president of Harvard and also a member of the Rubber Survey Committee, basically saying, “During the war, basic scientific research was shut down.” This was an all-hands-on-deck, we're going to essentially exploit our existing larder of scientific knowledge to fight the war. Now, sure, obviously there were developments in terms of technology and science during the war. I can talk about some of them. We could talk about jet engines. It's clear that jet-engine technology did advance during the war. But look, aircraft and aircraft-engine technology was advancing very rapidly in the 1930s. And you have to ask the counterfactual: What would've happened without that? As far as the United States, we never flew any jet engines in the Second World War.Nuclear power: We spent $2 billion on the Manhattan project and so on. And I think the first nuclear power plant was in England in ‘56, I think. And we obviously have relied to some degree on nuclear power. I think the jury is kind of still out on the extent to which that was a big plus. And it's operated only with enormous subsidies in terms of government accepting the liability limits and so on. So we could talk about other factors. There were some significant institutional consequences of the Second World War, but from a technological perspective, I do see it as a detour. And as far as basic science, I think this is one of those areas in which there is not a lot of dispute. It was shut down as was R&D development in terms of consumer durables.What sort of response have you gotten from other economists, other economic historians?There have been sort of people nibbling at the edges. They're not happy with one little thing, one or the other. But I think the reality is that World War II is not something that economic historians have given that much attention to. The time series, econometricians will typically drop the observations from World War II: “Ah, it was a controlled economy. Everything was messed up. We can't run our [models].” And so on. The basic thesis I have not gotten a lot of pushback on.When I saw that your book had come out, the first thing that popped in my head, since I write a lot about productivity growth, was a passage in Robert Gordon's book in which he very specifically writes about labor productivity in World War II and how the improved production techniques and so forth were not forgotten after the war. What you're describing is a very different view of productivity.What Bob Gordon did in chapter 16. . .Obviously you're familiar with it.I read all of the manuscript in chapters, so yes, I am quite familiar with the book. And what he did in chapter 16 was, I think, absolutely crystallized and state very clearly the second key theme, in terms of the conventional wisdom, about the war. He went beyond that. He then kind of advertised it as novel. But in the book, if you read the book carefully, I have considerable documentation because whenever you're trying to say something novel, you have to persuade people that we didn't already know this and so on. And what I think Bob is doing, basically, there is just absorbing and very clearly stating what is the received wisdom by many historians and economic historians. And I just think it's wrong.The US economy if WWII never happenedI think one of the more intriguing economic counterfactuals is what the American economy looks like in the ‘40s and in the postwar era if there was no postwar era—if all else equal, there was no need for a war. If we had not had this diversion, what does the economy of the United States in the second half of the 20th century look like?It is a counterfactual. One thing I would say is that the war did interrupt a very strong trajectory of productivity growth, both labor productivity and total factor productivity, as the output gap closed between ‘39 and ‘41. And what you're seeing there in terms of my interpretation is, number one, just a continuation of that trend during the Depression of very strong productivity growth, secular trend, combined with a boost also from closing the output gap because of the pro-cyclicality of TFP. Now, if you just were to statistically extrapolate that through the ‘41 to ‘48 period, things look pretty good. It's a questionable kind of exercise in terms of how accurate that would be.If you look t…

    When it comes to Up Wing thinking, there's no better litmus test than nuclear power. Setting aside the regulatory barriers we've imposed on ourselves, the United States can tap a source of clean, reliable energy that overcomes the carbon emissions and geopolitical challenges of fossil fuels. Here to make the case for nuclear in this episode of Faster, Please! — The Podcast, is Robert Zubrin.Robert is a nuclear engineer and the author of the new book, The Case for Nukes: How We Can Beat Global Warming and Create a Free, Open, and Magnificent Future.In This Episode* Is the case for nukes contingent on climate change? (1:14)* How the Atomic Age ended (6:39)* A 75-percent nuclear America (15:03)* Is a nuclear renaissance coming? (23:00)Below is an edited transcript of our conversationIs the case for nukes contingent on climate change?James Pethokoukis: Were it not for climate concerns, would there still be a case for nukes, or would you be writing The Case for Carbon instead?Robert Zubrin: No, there still would be a case for nukes. The primary case for nukes is to expand humanity’s energy resources. Regardless of climate change, we have an imperative to make energy more cheap and available. The primary problem in the world today is poverty. We have poverty in America, but in America, the average per capita income is $50,000 a year. Globally, the average is $10,000 a year. And half of the world is below average. So the existence of poverty in the world is quite prevalent. And that stifles people's lives. It kills people — people die of diseases that could easily be cured. They don't get educations. They suffer from malnutrition. They suffer from lack of opportunity. This is the thing that needs to be answered. We need to increase the availability of energy to put the whole world on an American standard of living. Once again, we still even have poverty here. We'd have to increase world energy five times. And fossil fuels cannot support that. So regardless of the issue of climate change or carbon enrichment of the atmosphere, we need more energy.And secondly, we need the energy to come from freedom, not from possession. It needs to come from the power of creation. A major problem with fossil fuels is it puts a lot of global power in the hands of people who just simply have it by force of possession, not through creativity. It gives wealth to those who take it rather than those who make it. For example the OPEC oil cartel could, as it did in 2008, constrict the world's energy supply below what it needs and send the price of oil up to $150 a barrel and cause a massive worldwide economic dislocation as a result. That's even a potential threat right now. Whereas nuclear power fundamentally comes from mind. That is, it’s the result of technological creativity: turning something that is not a resource into a resource — an incredibly abundant resource. So it moves power where it needs to be, into the hands of the creative, which is to say in the hands of the free.Let me continue on the theme from that first question: Why isn't it TheCase for Solar? I know that solar prices seem to have come way down in recent years. Why not that as the thrust of your book?The problem is this, that solar energy, and in this I would also add wind as well, are intermittent energy sources. They are not reliable sources of power with which to power an industrial civilization. They are useful boutique energy sources. Wind power has had a major role in the development of human civilization by powering ships. Worldwide commerce was enabled by putting wind to work as a classic example of off-grid power. Solar energy is predominant in space, once again, way off-grid. But if we're talking about the production of energy at scale in a reliable way to power industrial society, they simply do not cut it.Does solar still not cut it, even if we figure out new ways and better ways of storing that energy? That sounds like it's doable. We just need better batteries or ways of storing that solar energy for when it's cloudy out.There are a couple of problems there. First of all, the amount of solar energy to power Manhattan would cover most of Long Island — and try buying Long Island to put the solar energy capacity there. And then you have the problem with storage. First of all, the problem with storage on a planned basis, that is just storing for a night, is bad enough. And it basically increases the cost of a solar installation by like a factor of five just to do that. But what if it's cloudy for three days going? What if there's this thing called winter that happens? Which it does. Solar energy can be inadequate for months on end. Having the capacity to deal with that is simply not possible. So, in fact, solar energy power systems have to be 100 percent backed up by reliable sources of power, which to say either fossil fuels, nuclear, or hydroelectric.How the Atomic Age endedWhy did the Atomic Age end? Do we understand the culprits? Do we understand who the murderer was?I think I do. First of all, nuclear power in the ‘60s was so much cheaper than fossil fuel power that in the early ‘70s, we were getting orders in the United States for two new nuclear power plants per month. That's how fast it was coming online. And in fact, it caused alarm in the oil interests, who very early on tried to stop [Admiral Hyman] Rickover from introducing the nuclear submarine. Exxon and Atlantic Richfield both gave very large grants to the Sierra Club to go after nuclear power. And in fact, part of their fear was justified because after the oil price went up in ‘73, ’74, nuclear power actually cleaned the lunch of oil-fired electricity in the United States. In 1972, 3 percent of American electricity was nuclear, 20 percent was oil. Now it's 3 percent oil, 20 percent nuclear. Oil, of course, maintained its premier position as transportation fuel. There, it couldn't be dislodged. It has unique advantages in that realm.But what happened was in the late ‘60s and early ‘70s, there was an ideological offensive launched by Malthusians. You may remember two very important books from that period. One was called The Population Bomb by Paul Ehrlich. And another was called The Limits to Growth by the Club of Rome. That's ‘68 to ‘72. And then there were many less popular works. But they all said, “Look, we're running out of everything. We have to stop economic growth and population growth.” This was a very powerful ideological offensive, except for you may remember Julian Simon, who was an economist who said the Club of Rome was absolute nonsense. We weren't going to run out of everything, or anything, by the year 2000. But he was regarded by mainstream media as some Neanderthal from the Chamber Commerce. And if you look at the Sierra Club's statement, when they finally came out definitively against nuclear power, which was in 1974, what they said was, “We need to oppose nuclear power because it could encourage unnecessary economic growth.”And then they went on to say, “We can do this. We can stop them by stopping the establishment of any way for them to dispose of the waste.” And so they targeted nuclear waste disposal as a key weakness of nuclear power. And at that time, there were proposals in the works to just dispose of it by subsea disposal, which is easy to do. And when they got that block, and Jimmy Carter blocked that, they then opted instead for a much more elaborate program of storing the waste under a mountain in Nevada. They then campaigned against that. It baffles the mind how someone who claims to care about health and the environment can say it's better to store nuclear waste in nuclear power plants in the suburbs of major cities than under a mountain in Nevada. And yet they did. When they say there's no solution to nuclear waste disposal, there certainly is a technical solution. And the Nuclear Navy stores nuclear waste in salt domes in New Mexico. They just don't have to put up with any of this stuff. But they managed to stop the commercial nuclear waste from safely disposing of its waste and then say, “Hey, there's no way to dispose of the waste.” And they have collaborators in the Department of Energy and the Nuclear Regulatory Commission. If the FAA was run like the Nuclear Regulatory Commission, we would have no airplanes. If you have a totally hostile regulatory structure, you can destroy any industry.Can you think of particular regulations, perhaps, that you think played a key role? Or is it just broader than that?If I was asked to name one thing that is the big problem and which needs to be corrected if we're going to have a nuclear renaissance, it's the regulatory structure, what was put in place by the Carter administration — which by the way, was in infested massively with members of the US Committee for the Club of Rome. They established this regulatory structure. In the book, The Case for Nukes, I show the flow chart of what you have to do to get a nuclear power plant license in the United States. And it looks like a map of the New York subway system with a million stops and intersections this way and that way. And guess what? Each of those subway stops themselves involves another subway map inside of it. And some of these are really ridiculous. One of the subway stops, just one, is the Environmental Protection Agency, which among many other things demands to know, and have proof to its satisfaction, that the utility should build a nuclear power plant as opposed to a coal-fired power plant or a gas-fired plant, or no plant at all. Imagine if you had some land and you wanted to build a log cabin on it. And so you go to the municipal authorities and say, “I want to build a log cabin on this.” And they ask you not just for your plans to show that it's going to be a safe building, but to prove that it shouldn't be a chalet, or a cape cod, or a brick house, or a gas station, or a pet cemetery, or a zoo, or anything else.And then imagine that you actually do show that to the satisfaction of the authorities involved. But then there's now an opportunity for people who hate you to intervene in court to contest that approval. And now you have to go to court and prove to a judge and a jury that this in fact was the correct decision by the mayor. And if that court approves you, they can then appeal. That's what this is like. [Recently], we had a nuclear power plant go online in Georgia. It took 14 years to build it. Our first nuclear power plant in Shippingport, Pennsylvania, took three years to build. That is, the amount of time it takes to build a nuclear power plant has increased by a factor of five. And this is not because they've become more complicated. It's because the legal process become vastly more complicated.And if you look at the data, as the time it has taken to build a nuclear power plant has increased, the cost has increased as the time squared. And once again, I show this in the book. It actually follows this curve. It's not even just linear, where you have to pay people for longer periods of time, you're paying all these workers to hang around doing nothing, instead of putting things together. You're paying more expensive kinds of people. Lawyers cost a lot more than plumbers, and you're paying for more and more lawyers as this thing drags on and becomes a bigger and bigger and more complex deal. So this is what has stopped nuclear power in the United States. The time to construct nuclear plants should have gone down with experience, not been quintupled.Currently, and this is a number that's sort of holding steady, we get about 20 percent of our power generation from nuclear. What is the counterfactual? What is the right number? If the ideological war had not happened, and all those nuclear plants, those two nuclear plants a year, that kept happening. What does our energy mix look like today, do you think?In France today, it is 75 percent nuclear and 10 percent hydroelectric. So it’s only 15 percent fossil fuels. Here you have France under the leadership of Charles de Gaulle. He put together kind of a labor-industry alliance for growth that included both de Gaulle-ists and even the communists, who had a trade union. This is jobs, this is what we want. And they did it. And it's 75 percent nuclear. Meantime, here's Germany, with this massive green party, as well as green ideology infecting the social democrats and even the Christian democrats and the rest, shutting down their nuclear power plants. Germany's carbon emissions per unit power is five times that of France. Five times. There is the green Germany. And it's even worse than that, because a lot of Germany's power comes from biomass. And you have this romanticism of “We're getting our power from the forest.” Yeah, you're getting your power by killing trees and the animals that live in the trees. So how's that being a friend of nature? The way to be a friend of nature is to get your power from things that aren't involved with the natural biosphere. The person who saved the whales was Rockefeller, by switching us from whale oil to petroleum, because petroleum has much less involvement with the biosphere than the whales do. And you'll have even less involvement with the biosphere if you switch from fossil fuels to nuclear.A 75-percent nuclear AmericaHow do we get that 20 percent up to 75 percent?There needs to be, fundamentally, a societal decision. Now, one thing that very oddly works in our favor here, is that the Malthusians have oversold the case on global warming. Global warming is real. World temperatures have gone up one degree centigrade since 1870. And that's true; I don't dispute that for a minute. I dispute the fact that that is a great cause for alarm. But it's true. They have nevertheless managed to alarm people greatly, because they're trying to use global warming as a rationale for rigging up energy prices. Which is basically an extremely regressive tax. (Carbon taxes are just about the most aggressive sales tax you can have, because they don't even tax on the basis of price. They tax on the basis of mass, and a cheap cut of meat involves the same amount of carbon emissions as an expensive one. And a cheap dress involves the same amount of carbon as an expensive dress, even though one might be priced 10 times above the other.) They've oversold this. They actually got a lot of people [saying], “Oh my God, this is an existential problem. We have to stop carbon emissions.” If their primary concern actually is carbon emissions, a lot of them are saying, “Well, then why not nuclear?”So you actually have, at this point, a significant faction in the Democratic Party, and they have an organization called the Third Way, Cory Booker is a member of this faction, who say we should have nuclear power because there's an existential problem of climate change. They actually believe this. So this is the solution. The hardcore, they hate nuclear power because it would solve a problem they need to have. But these other people actually want to solve the problem. So there's some leverage there. The Biden administration, though, has responded to this faction in only limited ways. They have allocated some money to develop more advanced types of nuclear reactors. That's good.The nuclear reactors we have now are essentially the same thing that Rickover invented in the 1950s to power the Nautilus and the Shippingport plant. I don't think that that's a fundamental design flaw. Pressurized-water reactors, which is the Rickover reactor, is like 90 percent of all reactors, if you include the mild variations of it that are out there. It's a very good design. It is inherently safe. It cannot have a runaway nuclea…

    As space enthusiasts and entrepreneurs look to expand human civilization to the Moon, Mars, and beyond, few stop to examine the geopolitical risks of space colonization or the opportunity costs of not fixing problems on Earth. While most Faster, Please! guests advocate further expansion into space, Daniel Deudney offers a different perspective. Deudney is a professor of political science, international relations, and political theory at Johns Hopkins University. He’s the author of several books, includingDark Skies: Space Expansionism, Planetary Geopolitics, and the Ends of Humanity, released in March of 2020.This interview was first released in June 2021 for my AEI podcast, Political Economy, and now I’m sharing it with subscribers to Faster, Please! (Unfortunately, our chat preceded my viewing and reading of The Expanse, which does a great job suggesting Deudney’s concerns.)In This Episode* Space expansionism and its dangers (1:24)* Space infrastructure (13:57)* Hedging existential risk (18:13)* Principles for space policy (30:40)Below is an edited transcript of our conversation.Space expansionism and its dangersJames Pethokoukis: My listeners love when I read during these podcasts. I’m going to start by reading two quotes. The first quote is from Elon Musk:“You want to wake up in the morning and think the future is going to be great – and that’s what being a spacefaring civilization is all about. It’s about believing in the future and thinking that the future will be better than the past. And I can’t think of anything more exciting than going out there and being among the stars.”Quote two is from the Blue Origin website:“Blue Origin was founded by Jeff Bezos with the vision of enabling a future where millions of people are living and working in space to benefit Earth. In order to preserve Earth, Blue Origin believes that humanity will need to expand, explore, find new energy and material resources, and move industries that stress Earth into space.”Now, I think you would probably call both those visions “space expansionist”. But that is not your vision, right? So what don’t you like about those visions?Daniel Deudney: Well, Musk and Bezos articulate a vision of space expansionism that was first articulated early in the 20th century and has been subsequently developed. Bezos was actually a student of Gerard O’Neill, who was one of the main visionaries of space colonization in the United States during the 1970s. So they’re articulating a central set of ideas that is held by a large number of people, both in the United States and globally. And my book, Dark Skies, is really a systematic evaluation of the actual impact of space activities to date and a critical assessment of the likely impacts of many of these yet unrealized projects.So to start with the historical record, this is not a simple task because space is just a place. And so there’s a heterogeneity of activities that have gone on there. So it’s like summing up apples, light bulbs, and grenades. But the standard narrative of space activities to date, I argue, is woefully inaccurate. It leaves out one of our major space programs — and, depending on how you count, perhaps our major space program and arguably our most consequential space program — which is the use of ballistic missiles to deliver thermonuclear weapons at global distances in very short periods of time.The standard definition of space weapons is that they are weapons used against objects in orbit or placed in orbit. That’s completely insufficient because it leaves out the use of the frictionless environment of space as a corridor for rapid bombardment at distance. And so I say that we have this major space program that we don’t acknowledge as a space program. It’s what would be called an “unknown known.” Everyone knows that these exist, but they get misplaced or miscategorized. And if we put ballistic missiles back into the ledger sheet for an assessment of space activities to date, I have to conclude that the impact has been to increase the probability of nuclear war, which would obviously be a civilizational, perhaps existential, catastrophe for humanity. Take the Cuban Missile Crisis. The fact that these weapons move so rapidly — are so difficult to intercept — has created this unprecedented situation of vulnerability.And this really points to a more general fallacy of this very optimistic thinking about space, which is to simply neglect the violence potential and the tendencies for this violence potential to be harnessed. It’s like they think that space is good, and if something is not good, then it can’t be involved in space. The reality is that this major space program (that we don’t acknowledge as such) has been a major negative in terms of the survival of our civilization. And so the first step for the space expansionist, I think, is really to be a bit more realistic and accurate about what they’ve actually done and the inherently enormous violence potential involved in this domain.Is that your primary critique then? I mean, those are two very attractive visions. And is your main critique that they are just utterly ignoring how it could all go wrong? That they’re only viewing this as creating a space economy, creating space hotels, creating lunar or Mars colonies, or deflecting asteroids — but they’re ignoring how all these technologies could be used for ill?Yeah, that’s a general summation. The first key point is the ballistic missiles and space weapons. And then, looking at the larger future set of agendas that they advocate, colonization sits really at the center of it — millions, billions, or trillions of people living in space to make humanity a multi-planetary species. And their seemingly ace-in-the-hole argument is that the Earth is fragile — it’s vulnerable, it’s subject to all sorts of disasters. And therefore, we need to get all of our eggs out of this one frail basket.Seems like a good argument.At its surface, it does. And as they say, the reason the dinosaurs went extinct is because they didn’t have a space program.So let’s look at what would be entailed in humanity becoming a multi-planetary species: colonization of Mars, colonization of asteroids, and so forth. This would almost certainly produce an interstate anarchy. The assumption that the advocates make, and I think it’s well-founded, is that any colony which is big enough to provide existential risk insurance will be big enough to become politically independent. And once it becomes politically independent, we have to expect the same types of dynamics that have been characteristic of Earth history and interstate anarchy.Then we read the terrain, and we see immediately that it’s got this inherently enormous violence potential. And that’s because these objects — asteroids, even space debris — are moving so rapidly. The reason these asteroids are so destructive when they strike the Earth is not because of their mass, but because of their mass combined with their velocity. And so this is an environment that is inherently far more violent than any environment that we have dealt with on the Earth.So I asked the question: What is going to be the likelihood that we’ll have — as we have on Earth — wars and violent rivalries in what I call the Solar Archipelago? One factor, of course, would be the issues of mutual vulnerability, which I argue would be extremely high. The ratio of destructive capacity, like on Earth with nuclear weapons, is going to greatly exceed the territorial, habited locations. So saturation of violence capacity will mark solar-orbital space. Even though, of course, there will be a recovery of distance — it won’t all be quick because Mars is tens of millions of miles away, at least.Then you asked the question about rivalries over frontier resources. The historical record on Earth is that frontiers are very violent places. Rivalries for making claims will be very likely. So we have a war-prone argument there.Another factor: To what degree are the units like one another? On Earth, we think that units that are like one another — particularly if they are democracies — are less war-prone towards one another, and I think that colonies in space are likely to become very different than places on Earth. The advocates all say this. It seems intuitively obvious. And the most important difference that will invariably emerge will be a very fundamental one: biological species radiation. This is to say that the human species will start branching. This will occur inevitably, slowly, through processes of Darwinian evolution. But many of the advocates insist that we will do this more quickly with genetic engineering.And so it’s not only that we’re going to have multiple bodies in the solar system inhabited, they will be inhabited over time, almost inevitably, by intelligent species — at least as intelligent as us, with at least our levels of technology. But they will be radically different in their biological character than humans on the Earth.Look at all of the violence which has been sparked and justified by minor cosmetic skin-color differences on Earth, and think about what would happen if we have really different species. Let your imagination go here. The biological potentials for variation are enormous. It might well be that insectoid body forms will prove more appealing in space environments.And so we will have eventually a solar system that will be inhabited by aliens, but they will be descendants of Earthlings. And that to me is a very unappealing future. And I think that it’s almost an inevitable one once we cross over that crucial threshold to have a colony that is politically independent.Would that be your worst-case scenario? Look, I’d like a space economy. I would like there to be some space hotels. Maybe we do some manufacturing, see what happens.Space infrastructureSo I’m assuming that was your worst-case scenario. Do you have a positive space story? One that concerns you far less, at least?Tourism, within the larger scheme of things, is really kind of a trivial pursuit.In terms of space resources, we’re talking here primarily about the extraction of valuable metals from asteroids. That’s a civil technology that would require the ability to alter the orbits of masses of asteroidal material and asteroids in the solar system. Presumably, you’re going to insert these bodies into Earth orbit. So you’ll have to have highly precise capabilities to alter their orbits. And of course, we would also want to develop technologies to alter their orbits so that we can avoid them colliding with the Earth (although that’s not really a short-term problem).And so I look at this as a civil technology and I say, “How distinctive is this from the military technology?” And the answer is, it’s almost none. It’s a question of the trajectory. Once you have the technologies to alter the trajectories of asteroid-size bodies in the solar system, you’re going to have to tap into a violence capacity that will be millions of times greater than all nuclear weapons combined. So I say that allowing private enterprise to develop asteroidal mining, as seems to be the preferred American scenario, is kind of like allowing private enterprise to develop and have hydrogen bombs. It’s just not a good idea because of the enormous destructive potential.Many of the scenarios for near-Earth envision giant infrastructures in orbit. A favorite is collecting solar energy from orbit — we have this problem of immense importance with regard to the carbon loading of the atmosphere, and there’s lots of energy that can be collected in space and beamed down to the Earth.But thinking about that as an economic proposition, or even an ecological proposition, is insufficient. We have to also think about it as a political and military proposition. My view is that it’s not going to be possible to develop infrastructures in near-Earth space until we have overcome interstate rivalry. Think about the Chunnel between France and Britain. It’s unthinkable in a situation of interstate rivalry.So it could be that the creation of this apparatus — I call this Orbita — would require the pacification of interstate relations. That’s potentially good news. But the potentially bad news is that whoever controls Orbita would be able to control the Earth because these enormous quantities of energy could be readily weaponized to shoot down anything coming up from the Earth. So it’s like we have a village and we’re going to build a big castle next to it. We’re going to have to expect that the village will get dominated by the castle.Hedging existential riskRegarding inter-solar system conflicts, why would you be more worried about war with evolved insectoid humans than about an asteroid hitting the Earth? How do you begin to figure out which is riskier?I’m worried about the asteroid-hitting-the-Earth scenario. I’m not sure how to figure out which of those scenarios is more likely. But I know the one has happened before, and they keep telling us that it’s only a matter of time before it’ll happen again.That’s right, it is just a matter of time. It might be a long time before a significantly large one strikes. But you make a very good point, and you’ve asked me if I have a positive vision of space. I lay out what I call an Earth-oriented space program, which does include the development of techniques to deflect asteroids. But it should only be done by a consortium of states and should not be coupled with the development of economic exploitation.And look, if we do have asteroidal mining, then I think it’s very unlikely that actors of magnitude on the Earth would support colonization. If this is the great bonanza of mineral resources, the last thing we would want to do is to create a rival — Mars, in particular — that would be in a much more proximate location to exploit these. So I think that as the prospect of Martian colonization starts to become a real possibility, these types of concerns are going to be increasingly evident to people. This is what I refer to as the second great debate about solar-orbital space: What should we do? And I think that as it becomes real, these objections will become increasingly compelling to large numbers of actors on the Earth.What you’re ideally recommending is, I suppose, you would have us wait to go into space almost completely until we have a much different geopolitical situation here on Earth. And it seems like we’re going in just the opposite direction — it seems like we’re actually having intensive competition. So I would assume you would find that worrying.Yeah. I think that the directions that we’re headed in are largely disaster-prone. And of course, one of the directions that we’re going in that never gets talked about is continuing to modernize, replace, and improve the nuclear weapon delivery system. That is, as I said earlier, this major space program that we don’t acknowledge as such. And the United States has, during the Trump era, declared the objective of dominating space. And this is something that has long been talked about by various military visionaries. But this was an important threshold that we have crossed.The SpaceX Corporation, as I’m sure everyone listening to this podcast knows, has lowered significantly the cost of accessing near-Earth orbit — by a kind of order of magnitude, perhaps. And they have these plans to build even larger rockets that they make claims about even further reducing the cost of accessing near-Earth orbit. And this is widely hailed as a great advance.I look at this, and I say, “Well, it’s going to lower the cost of doing stuff in space.” And the question then is: Which of this stuff is going to get done? And of course, immediately the military is interested. The idea that we can dominate space is going to depend upon having the capacity to put significant mass into orbital space.So I think that we have been misperceiving the overall character of this environment. We’ve been misrepresen…

    Thanks to SpaceX, it’s getting cheaper and cheaper to launch stuff into orbit. But just imagine if instead of using rockets, we could send cargo and people to space on an incredibly tall elevator. This may sound like a total sci-fi idea, but it has some grounding in real-world physics. In theory, we could build a space elevator by putting a counterweight in geostationary orbit and attaching a cable between the satellite and Earth. An elevator could then climb the cable, delivering payloads to space at a fraction of the cost of propulsive rockets. As you can imagine, it isn't quite that easy, which is why I'm joined today by Stephen Cohen.Stephen teaches physics at Vanier College in Montreal and has been working on space elevator concepts for almost 20 years. Recently, he wrote “Space Elevators Are Less Sci-Fi Than You Think” for Scientific American. Stephen also has a new book, Getting Physics: Nature's Laws as a Guide to Life, which was released earlier this year.In This Episode* Space elevators 101 (1:42)* The engineering challenges (7:14)* The economics of space elevators (11:07)* Space elevators in sci-fi (19:21)Below is an edited transcript of our conversation.Space elevators 101James Pethokoukis: In the intro, I tried to do my best at explaining what a space elevator is. But the simple version is we have something big and heavy in orbit, a cable extends down from that thing, attaches somewhere on the Earth, and we run an elevator up and down it. That's a space elevator. Am I right?Stephen Cohen: Sure.Now that we have a picture in our heads, why is it something more than just an interesting engineering thought experiment? What attracts you to it, other than sort of a technical problem that would be interesting to solve on paper?Well, it's space infrastructure, which is something we don't currently have and never have had. Right now, and for all time we've accessed space, going to space is like a one-off each time. Sometimes you have some reusable parts, but basically what a space elevator is, is a bridge instead of just a bunch of boats.And the advantage of a bridge over boats is what?Access. Right now, each time you want to plan a mission, to simply put something into orbit requires a lot of planning. The weather has to be right. And then you want to plan another mission, you sort of have to begin again. With a space elevator, you can just days in advance say, “Okay, we're going to send something up to a desired orbit.” And just hours later after that one would be sent, you could send something else. And you basically have a housing — that's what the climber is, effectively — that you put the payload inside and up it goes. That's the transformative part. But we haven't talked about really the cost savings, the energy savings, and that's just basic physics.The way you get around in general is by applying forces. And that's something you do without thinking. When you walk, you push on the ground. When you fly through the air, you're basically pushing on air molecules and they push back. But in space, you have none of that. And so what rockets do is they literally are the medium. The fuel you bring is the medium you're pushing against — rather, you're throwing it out the back. It's a hugely wasteful, inefficient way to get around. It's preposterous when you think about it. But it's the only way we can get things to the speeds we need to get them to. Just as a mode of getting things into this is extremely practical. You can't compare the efficiencies. It’s orders of magnitude of difference.It really strikes people. When they hear the general concept, they really think it's something big and it sounds like it's amazing. It's something that is science fictional, but maybe we could turn into science fact. There's something else about it, I think, that just grabs people's attention.Yeah, for sure, because it's a physical connection to space. It's like, if you could just touch the cord at the Earth port, then you're in contact with something that's reaching out all the way into space, which is wild. But I think there's an element missing. People don't realize tethers in space are not a new thing. We've had missions since the ‘70s that are effectively two bodies orbiting earth connected by a long tether, sometimes kilometers long. Now, that's not in the ballpark of 100,000 kilometers long, which is a common number thrown out there for what the eventual space elevator might be. But a lot of the same technologies are involved. The biggest difference is of course, instead of two bodies connected by a tether, like a big spacecraft to a small spacecraft, say, this is a big structure connected all the way to Earth. The amount of tension is tremendous. That's the big difference. That's what effectively becomes the big engineering challenge about it all.To be clear, the cable would be connected to something large in orbit, and that could be something we build, but I've also heard maybe it could be a small asteroid? Am I confusing two different things there?It doesn't have to be something we build, but likely it won't be an asteroid. The way at least the first space elevator will likely be constructed would be you send the cable up in a spacecraft and you drop it, you sort of spool down the cable over time. And it would be a lengthy unspooling. The dynamics of that are super interesting. But the point is, at the end of it you can now connect that cable to the ground. It's good to have something functional at the other end, not just some mass. Of course, the mass you're going to have at the far end, the particular value of that mass, that depends on how long the cable will be. So to achieve an equilibrium, you can't just choose any random mass. It would have to be planned.The engineering challengesLet's get to some of the challenges. And as you answer those questions, we may also find out why you think this is something that can be done. You mentioned that cable. That seems to be the chief engineering issue, as you mentioned: finding an ultra-strong lightweight material to make up that cable. Is that something that needs to be invented? Are we talking an innovation? Do we need radical new science, or can you see how that cable could be manufactured in a decade if we got serious about funding that kind of research?The key property is called specific strength. It's not just strength, but it's the strength-to-density ratio. And that property in the material existed since the mid-‘90s. But it's very costly to produce. Time consuming as well. Now, on both fronts, there have been big improvements since then.Are these carbon nanotubes? I always hear about carbon nanotubes. Is that what you're talking about?The two candidates that are talked about these days are carbon nanotubes and just graphene. These options, there are some issues with repeatability. So the process, you think you're doing it the same twice, but you don't get exactly the same properties each time. It still needs to mature, but the basic science is there. It's become a materials engineering kind of problem.Is it an engineering problem that we just sort of have to work the problem, and it'd be great if we had funding, but it doesn't require a radical breakthrough? We think we know how to get there. It's just sort of resources and effort and time.Yeah. Yeah. There are probably solutions to every problem that stand in its way. I would say as the material problem is getting solved and as time is going on, a new problem is entering that is on the same level as the material problem. And that's our very, very crowded space environment. That is only becoming a bigger issue. That problem is only going to get worse with time. And the equator is a fairly busy area. It's very likely that the space elevator will be situated slightly off-equator, and the mechanics of that are sound. That's not a big issue.On land or in the ocean?Probably in the ocean, is the proposals I've seen. Those are sort of the details, I would say. And it will come down to economics, won't it? We're still at the stages of design, but there's really no company that is clearly in charge and no administration, institution is pulling all the strings. What we have right now is a big project with a bunch of academics scattered around the world that are, I would say, dabbling in it. A lot of work has taken place. I would say low-intensity work. That is, you get 10 very useful studies done in the course of a year. That's peanuts for something on this scale. There needs to be probably a champion or several on the business side, I guess. But also governments need to get involved for this to really take off.The economics of space elevatorsIt must be annoying that you can't find a super billionaire — they seem to be very interested in rockets. You need to find one who's interested in a space elevator. That would seem to be an important piece to the puzzle when you look at how things are going in space and rocketry.Yeah, on the economic side of things, if you want return on investment, you probably need to work on steps to get there. So partial space elevator, that's something which is basically a larger space tether. Space tether on the order of thousands of kilometers. So it's an easier challenge, but the payoff isn't nearly as high. There need to be small aspects that are worked on that have return on investment that get you there. There are several that could be listed. If I could speak about the big investor of which you just mentioned, there's another project that really reminds me of the space elevator: something called Breakthrough Starshot that you haven't heard of it. It's an attempt to send something interstellar. To send to another star system a very small payload, on the order of grams, that we could then once we get there take a picture of, say, an exoplanet and send it back. And we’d get something way cooler than what our best satellites can do. That project also has a few major engineering challenges, but I wouldn't say science challenges. We're now at the point where there's a road to it. It's also probably decades away. It has spinoff technologies. They're really very similar. And the interesting thing is, there seem to be investors putting more money into that one than space elevators. That's my impression. Not boat loads of money.Isn't that a Mark Zuckerberg thing? Hasn't he put money in that?I don't think he's the only one.Yeah.I'm not fully aware of all the happening surrounding Breakthrough Starshot, but it's worth mentioning that the space elevator is completely transformative for life in our solar system, really. We talk about colonizing the Moon and Mars, and that would be really neat. But it's sort of a pipe dream if you can't support it. Sending a single person or several to Mars, that's a big, big undertaking. But now for them to live there in a supported way? The amount of mass you have to get there is tremendous. And you can't do this in a sustainable way without infrastructure. The point I'm making is, a space elevator [is] really transformative for the solar system. And I don't want to speak down on Breakthrough Starshot. I don't want to speak ill of that project. Totally cool. I'm on board. But that one, I would say, is transformative in the sense that you can actually send something to another star. We've never done that before. But it wouldn't change life as we know it, unless our picture happens to show something living on an exoplanet.Someone else's space elevator, perhaps!.It's really the economics and efficiency of getting something off the ground, into orbit. Has that economic potential calculus been changed, or would it be changed, by reusable rockets? I mean, when you first got interested it was probably either pre-SpaceX or maybe SpaceX’s early days, and those costs have come down and are expected to continue come down. At some point, does that make a space elevator irrelevant?Before we get to the cheaper chemical rockets, there are other changes that have taken place. For example, nuclear rocketry. There's also the idea of solar sails and things like that. But of course, none of those can address the primary reason why a space elevator is useful, and that's to get out of the Earth's gravity well. That's where you need chemical rockets or, well, nothing else. Nothing else will do it, because you need a tremendous amount of power in order to reach those speeds, unless you can just climb along a cable. Of course, those chemical rockets get cheaper. It doesn't mean they necessarily become routine, in the sense that weather will always be an issue, safety always a concern. They're not green, and if you intend to get really serious about space in the way people are talking about it, we are talking about such wasteful practices there. It's just unconscionable in a way. That's not the economic side, I realize. But an economic study needs to probably be repeated regularly to see whether this is the best way forward, purely based on economics. Access, environmental considerations: Those are other elements that also need consideration. But the economic story, I'd say, is evolving. Chemical rockets will always have a certain ceiling that you just can't beat, and we're maybe getting close to it.If I got into a space elevator capsule on Earth, how long would it actually take to get up to a space station?In all likelihood, there will be a station at geosynchronous that's 36,000 kilometers high — so about three Earths away — and it will probably take a week to get there if you could go in the area of the high-speed trains we've become accustomed to on Earth. That would be beautiful views for a week. What's cool is as you go up, the weight you feel goes down gradually until you reach this geo place. And then you are indeed weightless, just floating there like they do in the ISS. However, you'll have passed the ISS a long, long time ago, because that's only 300 kilometers off the surface of Earth. You couldn't put a station there on the space elevator. Physically that just wouldn't work. Geostationary is the ideal place for a space station because it imposes no new tension on the cable. In any case, it would take a week, is the short answer to that question.But that week would be a far more relaxing experience than taking a rocket.And let's be clear, this would be way cheaper once you've got it. Operating one of these, you wouldn't pay millions of dollars a person. Not even close. I can't know exactly what the number would be, but it could be 100 times less for one person once this thing's really up and running. Plus you don't have to spend a week going to geo and a week coming back. If we're trying to recreate the experience of going up to 300 kilometers, it could be an hour up and down and you've achieved a nice view of Earth.Space elevators in sci-fiIt's an interesting concept, but one which is probably used more in scientific literature than in movies and TV shows. I think the first time I ever saw one on a screen was in the recent TV series based on Foundation by Isaac Asimov where they had a space elevator. Now, of course, the space elevator — spoilers — the space elevator in that show, there's a terrorist attack and it falls down and just kills…Is there a portrayal of this technology in science fiction that you're aware of or that you think is interesting?There's som…

    "You can see the computer age everywhere but in the productivity statistics," said Nobel laureate economic Robert Solow in 1987. A decade later, the '90s productivity boom was in full swing. Likewise, it took decades for electrification to have an impact on productivity growth in the early 20th century. Today, artificial intelligence can write a coherent paragraph or generate an image from a simple prompt. But when will AI show up in the statistics, boosting productivity and then economic growth? Avi Goldfarb joins Faster, Please! — The Podcast to discuss that question and more.Avi holds the Rotman Chair in Artificial Intelligence and Healthcare at the University of Toronto's Rotman School Of Management. He's also co-author, along with Ajay Agrawal and Joshua Gans, of 2022's Power and Prediction: The Disruptive Economics of Artificial Intelligence.In This Episode* Prediction at scale (1:34)* How AI has transformed ride hailing and marketing (5:37)* The potential for “system-level” changes (11:26)* When will AI show up in the statistics? (16:12)* The impact of ChatGPT and DALL-E (19:46)Below is an edited transcript of our conversation.Prediction at scaleJames Pethokoukis: What this book is about—and then you can tell me if I've gotten it horribly wrong—this is a book about machines making predictions using advanced statistical techniques. 1) Is that more or less right? And 2) why is that an important capability?Avi Goldfarb: That's more or less right. The only place where I [would offer] a little correction there is, the reason we're talking about artificial intelligence today is almost entirely due to advances in computational statistics. Yes, it is just stats and that sounds kind of unexciting. But once we have prediction at scale, it can be really transformative to all aspects of business in the economy. There's a reason why we're calling computational stats “artificial intelligence” and we didn't use to.Prediction at scale. That's a great three-word description. Probably why you used it. To what extent is that now happening? The name of the book is Power and Prediction: The Disruptive Economics of Artificial Intelligence. Is this prediction at scale already disruptive to some degree or is it, will be disruptive?The technology, for the most part, is pretty close to there, in the sense that we can do prediction at scale because we have the data and we have computational power to do all sorts of amazing things. For the most part, it hasn't been disruptive yet. And it hasn't been disruptive yet, just because we have the technology doesn't mean we know how to use it well and we know how to use it productively in our processes and systems in order to get the most out of it.Are there sectors currently doing this, but they're not doing it well yet? It’s in a variety of sectors, but not enough companies doing it? Lots of companies are already using these machine learning tools, but they tend to be using them for things they were already doing before. If you had some prediction process to predict, if you're a bank, whether somebody's going to pay back a loan. In the very old days you'd have some human, the loan officer, look the customer up and down and go with their gut. And then, starting in the 1960s and especially in the ‘90s and beyond, we started to use scoring rules, partly your credit score and partly other things, to get a sense of whether people are going to pay them back. And so we were already doing a prediction task done by a machine. And now increasingly we're using these machine learning tools. We're using what we're calling AI, over the past five to 10 years, to predict whether people are going to pay back a loan. We're seeing those kinds of things all over the place, which is: You had some prediction, maybe you’ve used even a machine prediction before, and now we're using machine learning. We're using AI to make those predictions a little bit better. Lots of companies are using that.That sounds incremental. That sounds like an incremental advance.It's absolutely an incremental advance. We call these point solutions, which is, you look at your workflow, you identify something that a human is doing. You take out that human; you drop in a machine. You don't mess with a workflow because it's always easier to do things when you don't mess with a workflow. The problem is, when you don't mess with a workflow, there's only so much gain you can get. We've seen AI-based point solutions, prediction point solutions, all over the place. We haven't seen real transformation in very many industries. We've seen it in a couple. We haven't seen it in very many industries because real transformation requires doing things differently.How AI has transformed ride hailing and marketingDo you think that it has happened in one or two industries that you think would actually meet that bar of transformational? Can you give me an example?Absolutely. If you wanted to be a cab driver in the city of London 20 years ago, or even today, it takes three years of schooling. Learning to navigate those streets is really, really hard. And especially learning to navigate and predict where the traffic is going to be is really, really hard. And so there is a really rigorous process to screen people to be taxi drivers. In the US 30 years ago, there was something like 200 or 300 taxi drivers in the whole country. About 15 years ago, two technologies came about. The first one being digital dispatch, which is essentially tools for drivers to find riders, sometimes through prediction and sometimes through other tools. And then the second part was what's been disruptive with respect to that three years of schooling in the city of London, which is prediction tools for navigating a city. This is your GPS system.In the early days, many people selling digital dispatch and navigational predictions were selling them into professional driving companies, into taxi companies. “Hey, your taxi drivers can be 15 percent more efficient if they know the best route at this time.” That's what we call a point solution. You’re already doing this, you take out some part of the human process, you drop in a machine, and you do it a little bit better. A couple of companies realized that digital dispatch combined with navigational prediction could create an entirely new type of industry. And this is the ride-hailing industry led by Uber and Lyft and others. That's a totally new kind of way to do personal transportation that made millions of amateur drivers as good as professional because they could navigate the city and find riders.Example number one is the taxi industry. Personal ride-hailing, for lack of a better word, has been transformed partly through digital and really those maps are important—and a big part of those maps is machine learning tools and figuring out where the traffic is, etc. So industry number one.Industry number two is advertising. I don't know if you've seen the TV show Mad Men. That was really how the advertising industry operated well into the ‘90s. Maybe not the soap opera aspect of it. Maybe, maybe not. I don't know. But the idea that there's a lot of wining and dining and charming people to convince them to spend millions of dollars on an ad campaign. And whether a campaign worked or not was largely based on gut feel. And which kinds of customers you targeted and which TV show and which magazine, all of that was priced based on intuition and not much else.Digital advertising came along in the late 1990s, and the first ways we thought about digital advertising was that it was like the magazine industry. So instead of advertising in People magazine, you're going to advertise on Yahoo using the exact same processes you did in People magazine. There was a rate card and it was going to be so many dollars per thousand users. And if you were doing general search, it might be $10, and if you're looking for real estate, it might be $50. And that's exactly how the magazine industry was priced. Some magazines were more than others based on readership and topic. And it was all based on personal selling, intuition, deals, etc.Then people realize that digital advertising created an opportunity to predict who the user was, who might see your ad. A user arrives at a publisher and an ad needs to be served, and you can predict who that user is and what they might want and when they might want it. Based on those predictions, rather than just do the magazine industry old way of doing things, you can now serve the right ad to the right person at the right time. Starting around 2000, there were all these innovations in online advertising that led to an industry that today looks almost nothing like the industry that you saw in Mad Men. Every time a user goes to a website, there is a real-time auction, in fractions of a second, between, in effect, thousands of advertisers for that user's attention. And there are all these intermediary steps, lots and lots of intermediaries—largely led by Google, but some other players that complement Google in that process—to create an entirely new kind of ad industry. The ad industry has had a system-level change because we can now predict, for a given impression or given user who's looking at a page, what they might want and when they might want it. Predictions changed the industry.The potential for “system-level” changesHow confident are you that this technology is powerful enough that we'll see system-level changes across the economy? That this is a general-purpose technology that will be significant? And do we have any idea what those changes will be, or is it, “They'll be big, but we don't know exactly what they are.”The technology itself is pretty extraordinary. And so in lots and lots of contexts, I'm pretty confident the technology's going to get there. There are some constraints on it, which is that you need data on the thing you're trying to predict in order for the predictions to work. But there are lots and lots of industries where we have great data. The technology barriers, I think, are being overcome. In some industries faster than others, but they're being overcome in lots and lots of places.That's not the only barrier. The technology is barrier number one. Think of an industry that I'm particularly excited about the potential of the technology, which is healthcare. Why is it so exciting for healthcare? Because diagnosis is at the center of how healthcare operates. If you know what's wrong with somebody, it's much easier to treat them, it's much less costly to treat them, and you can deliver the right treatment to the right person at the right time. Diagnosis, by the way, is prediction. It wasn't obvious, the way we thought about that in the past. But really, what it is, it can be solved [with] statistical prediction by using the information you have, the data on your symptoms, to fill in the information you don't have, which is what's actually causing your symptoms. If you do a Google Scholar search for something like “artificial intelligence healthcare,” you'll get a few million hits. There are lots of people who've done research producing AI for diagnosis. The technology, in many cases, is there. And in lots of other cases, it's pretty close.That doesn't mean it's going to transform healthcare. Why not? What's an AI doing diagnosis? They're doing a thing that makes doctors special. Yes, a good doctor in their workflow does all sorts of other things — they help patients navigate the stress of the healthcare system, they provide some treatments, etc. — but the thing that they went to school for all those years for, and for many of them the thing that they have that nurses and pharmacists and other medical professionals don't, is the ability to diagnose. When you bring in machine diagnosis into the healthcare system, that's going to be very disruptive to doctors. There are lots of reasons why, then, doctors might resist. First, they might be worried about their own jobs. Second, they might just not trust the machines and believe they're good enough. Because [in] the medical system doctors are a core source of power—they help determine how things work—they're going to resist many of the biggest system-level changes from AI-based diagnosis.And so you may have regulatory barriers, you may have organizational incentive barriers, and you may have barriers from the individual people on the ground who sabotage the machines that are trying to replace them. All of these are reasons — even if the technology is good enough — that AI in healthcare may be a long way away, even though we can see what that vision looks like. In other industries, it might be closer. In lots of retail contexts, you’re trying to figure out who wants what and when — Amazon's pretty good at that in lots of ways — and in-store retailers can do that too. And so there are reasons to think that disruption in many retail industries will come faster.I just want to be a little careful here. I see the technology is there. There are some barriers on the technology side. If the payoff is big enough, I think most of the technology-related barriers can be overcome. To give you a sense of this: We hear a lot something like, “We don't want to do AI in our company because it's just so difficult to get the data organized and get the right data to build those predictions.” Well, yeah, it's difficult. But if the payoff is going to be transformative to the company and make the company millions or billions of dollars, then they'll spend thousands or millions in order to make it happen. And so a lot of the challenges aren't tech specific. They're incentives and organization based.When will AI show up in the statistics?I think of the classic Paul David paper about the dynamo. It took a while before factories used electricity, and they actually had to redo how the factory was designed to get full productivity value. And you say that we are sort of in the “between times.” And that makes me think of a classic Solow paradox: We see computers everywhere but in the statistics. He said that in ’87. Are we, like, in the 1987 period with this technology? Or are we now in the late ‘90s where it's starting to happen and the boom is about to begin?I think we're in the early ‘80s.Not even the late ‘80s?He said that in 1987. By 1990 it was showing up in the data. So he just missed it.[We’re in the early 1980s] in the sense that we don't quite know what the organization of the future looks like. There are reasons to think for many industries it might take a long time, like many years or decades, for it to show up in the productivity stats. While I do say we're in the early ‘80s because we haven't figured it out yet, I'm a little more optimistic that maybe it won't be 30 years to really have the impact. Mostly because we just have the lessons of history. We know from past technologies, and business leaders know from past technologies, electricity and the internet and the steam engine and others, that it requires some system-level change. And we now have the toolkits to think through, how do you build system-level change without destroying your company?When electricity was diffusing in the 1890s, there wasn't really any idea that this might take 40 years to figure out what the factory of the future looks like. It just wasn't on anybody's mind. The management challenges of redesign were unstudied, and there was no easily accessible knowledge to figure that out. Jump forward to the ‘80s and computing: Again, we hadn't even…

    It was only three decades ago that astronomers first discovered planets outside our solar system. Since then, astrophysicists have found more of these "exoplanets" — including some Earth-like worlds that exist in their star's habitable zone. Today, astronomy has moved far beyond pointing a lens at the night sky, so I've brought on Gioia Rau to describe her work on exoplanets, as well as how AI and recent declines in launch costs will change astronomy.Gioia is an astrophysicist and program scientist at Schmidt Futures. Previous to joining Schmidt Futures, Gioia was a research scientist at NASA’s Goddard Space Flight Center.In This Episode* NASA’s exoplanet discoveries (1:19)* Innovation in telescopes and astronomy (5:57)* The near future for astronomy (16:02)* Americans’ enthusiasm for space (22:04)Below is an edited transcript of our conversation.NASA’s exoplanet discoveriesJames Pethokoukis: When I hear that there's been a discovery, that NASA has discovered an Earth-sized world inside the habitable zone of its star, I think, are there people there? Is there intelligent life there? When you hear that, what do you think? What strikes you? What are the implications you draw? What do you want know more of?Gioia Rau: That's a great question. As a scientist, I have many questions after this discovery. I would like to … discover which other molecules are in there. I would like to understand better what the size of this planet [is], what is its atmosphere and its surroundings. But as a human, as a person, and also as a scientist, it completely blows my mind. I'm so excited by the multiple discoveries. The James Webb Space Telescope is great to understand the atmosphere of these exoplanets, but what really kept us going from zero to 5,300—where we are now in terms of how many exoplanets have been confirmed—is first Kepler and then TESS.What is TESS?TESS is another telescope of NASA. It has discovered many, many exoplanets. It has scanned both atmospheres of the sky. And actually, at NASA, my group has used TESS with light curves … [and a] neural network, and so through artificial intelligence we were able to discover 181 new planet candidates. Those are incredible machines. Let's say TESS is our searcher, but then to really understand what is in there, what's the composition of this planet, we need …How many Earth-like, in a very broad sense, worlds have we found that are in habitable zones?That’s a very good question, and I don't have the number on the top of my head, but those are just a bunch.At some point we had discovered none. And it wasn't that long ago that we probably had not discovered any of these?Right. The difficulty is in defining what is Earth-like. There are multiple meanings of this. One is the distance from the parent star that is similar to the distance between the Earth and our own sun. So this is called a “habitable zone.” But another measure of Earth-like is the size of the planet, or the fact that it's rocky versus gaseous. Definitely, TESS is the telescope that has helped us a lot with such discoveries.And even before we had found any of these, I imagine there was considerable speculation that obviously they had to exist, there had to be all kinds of planets outside our solar system. But we had not discovered them. And yet, I imagine it's been a pretty wonderful run we've had from going from pure speculation to beginning to analyze what these planets, whether they're Earth-sized or not, what other worlds are like.Absolutely, and it's just about 30 years, 33 years, that we’ve known that, actually, other planets, exoplanets—which by definition are planets outside our own solar system­­­­­­—exist. Before it was, as you mentioned, just a speculation. But the first ever planet was discovered around 33 years ago. And so since then, really our revolution began. And, actually, these two scientists that co-authored and discovered the first exoplanet have just recently been awarded the Nobel Prize.Innovation in telescopes and astronomyIt might seem to some people that NASA hasn't really done much since the Apollo program. But there's a lot more to space science than crewed missions. It seems to me like NASA’s doing a whole lot of things right now.Absolutely. The time we are living now is a time of revolution for so many aspects in space exploration. Not only human exploration, which of course during the Apollo time peaked, and now hopefully also with the Artemis mission, named after the sister of Apollo in Greek mythology, is coming. But the James Webb Space Telescope, which is really a marvel of engineering. We never before have thought that we could put a telescope inside the rocket like an origami and then deploy it in the atmosphere. And we are discovering with Webb so many different things about the universe. Our early universe: Webb is basically a machine to look back in time. With its infrared vision, we will be able to look back over 13.5 billion years. But also with Webb we can discover galaxies over time, again, with the infrared sensitivity. So to discover even the earliest and faintest galaxies. We can discover the life cycle of the stars, as in the infrared, Webb which is able to look through the dust clouds which are otherwise opaque to the visible light. But also we are, as we mentioned before, able to see the atmosphere of these exoplanets, and so understand if in there there are building blocks of life elsewhere in the universe, but also understand how our own solar system was formed.Currently, we're learning about exoplanets through astronomy. We aren't sending probes. Are we nearing the point where there isn't much we can learn without getting closer to these worlds? Or can you imagine further innovations which would allow us to learn a lot more about an exoplanet without sending something there?This is a great question. We had Hubble in the past, the Hubble Space Telescope, through Kepler and TESS, now with James Webb and in the future with the Nancy Grace Roman Space Telescope, we will be able to understand so many different aspects of the “zoology” of this planet, so to say, but also on the composition of the atmosphere and so on. And so basically up to now, [there are] five principle methods to discover exoplanets. For example, one of those is transit, the method that Kepler and TESS use; but another one is gravitational microlensing, which the Nancy Grace Roman Space Telescope will use.Now, what is that?Gravitational microlensing is basically an observational effect that was predicted in 1936 by Einstein using the theory of general relativity. But this effect was never actually proved up to now in space. Basically when one star in the sky passes near or in front of another, then the light rays of the background star become basically bent due to the gravitational force, the gravitational attraction of the foreground star. And so this star then is actually acting as a virtual magnifying glass or a lens, and so it amplifies the brightness of the background source star. And so we refer to the foreground star as a lens star, and if the lens star harbors a planetary system, so an exoplanetary system, then those planets can actually also act as lenses, and so each of these planets will be producing a sharp division in the brightness of the source. And so we discovered the presence of each of the planets in this way, and we are able to measure also its mass and separation from the star. And this technique also tells us how common Earth-like planets are. This is a great method for Earth-like planets and has guided also the design of this future space mission, the Nancy Grace Roman Space Telescope.What would you like to be able to find out about an exoplanet, that you currently can't, but you think you might be able to 10 years from now or 20 years from now?There are several aspects that are currently unknown, probably what we need the most, that the Roman space telescope will also help us understand—Roman will be launched in May, 2027, according to the forecast, and it'll be operational a few months after—but basically Roman will have a wide field instrument that will bring us a panoramic view, a wide field of view, that is 200 times larger than Hubble Space Telescope in the infrared. It will also combine the power of imaging and spectroscopy, and so in this way, we will uncover thousands of exoplanets beyond our own solar system. We will have basically a sense of the “zoology” of the exoplanets, but also, we will have in the future, hopefully, much higher resolution of spectroscopy which will really [help us] understand what molecules are there beyond what JWST is able to tell us. And also if there is water, if we can go there, considering that many of these planets are not that far away, I mean in an astronomical point of view, right? They are just a dozen or hundreds of light years away, which is not that far away.How did you get involved in this to begin with? As a kid were you a space nut, you loved reading about it or watching documentaries? What got you interested in the field?Since I was a little kid, I was literally dreaming about space. I was very curious about everything about science in general. But something about space was extremely fascinating for me. This feeling of looking at the universe and feeling small in comparison of the immensity of the cosmos, dreaming of exploration while watching the space shuttle launches in the ‘90s. And also, you know, this question that we are still trying to uncover: What is out there? How does the universe work? How did we get here? Those were all fascinating to me as a kid. And yes, since I [was] very little kid, I wanted to work for NASA. I even wrote NASA a letter when I was about age eight. I wanted to attend their summer camp—obviously from my accent, I was not born in the US, so unfortunately at the time, it was precluded for foreigners to attend their summer camps. But they wrote me back. They were like, “Study and one day you'll come back here.” And so I didn't give up.And just explain a little bit about the thrust of your work now at Schmidt Futures.At Schmidt Futures we do several things for astronomy in general and for space. Fascination of space, of course, drove me to do research. Like very hands-on research. And then of course, I evolved and I started to lead research groups and to have my own students and interns and so on, which I love. I love to mentor young students and get them inspired to do science. But then also I like this more managerial or programmatic aspect, at Schmidt Futures we are really forging what the future of astronomy and astrophysics will be in the next five­­, 10 years and beyond. And so this has been extremely thrilling to me.The near future for astronomyYou were talking about how this is kind of a revolutionary period in space science. How important in this period, and let's say over the next decade, are two things? (1) Artificial intelligence to help process all this data, and (2) the fact that it's getting cheaper to put probes in space and put telescopes in space. I imagine those costs are going to continue to come down.Absolutely. I believe that the future of astronomy and astrophysics in general will be about an accelerated timeline and about cutting, drastically, costs. And so this is where also I really want to focus, especially for future of astrophysics. Concerning artificial intelligence and its use in astronomy, this is truly revolutionizing how we do astronomy. NASA is doing a lot in this sense. As I mentioned earlier, through AI we discovered a bunch of new planet candidates. But AI in general is revolutionizing astronomy in many ways from understanding cosmology to understanding the shape of galaxies and how they form. And I'm noticing more and more AI-based applications to the exploration of astronomical data. And so this is definitely, I believe, the future of astronomy. In a decade or so there will be more AI-based applications to analyze astronomical data than manual ones.I know there's ideas about putting a variety of telescopes on the Moon. And there's all this concern lately about our sky being cluttered with satellites, and a lot of astronomers are complaining about the Elon Musk Starlink, that it's obscuring views. But I would imagine that putting some kind of telescope—and radio telescopes, I imagine a variety of them—that would be helpful, right? Putting them on the Moon as opposed to having them on Earth?Oh yeah, absolutely. Actually, I believe that the future of [ground]-based astronomy, as we call it, versus space-based—“space-based” are all the telescopes that [orbit] around earth or in space …, versus [ground]-based are the telescope that we build on Earth—but the future of space-based astronomy is actually from the Moon and also beyond the Moon. In particular, for the radio wavelength domain, our radio telescope on the far side of the Moon will have tremendous advantages compared to Earth-based and also Earth-orbiting telescopes. For example, such a telescope could observe the universe at wavelengths greater than 10 meters, which are reflected actually by Earth’s ionosphere and so are up to now completely, largely unexplored by humans. But also the Moon acts as a physical shield that isolates the lunar surface telescope from any radio interferences or noises from the Earth-based sources, from the ionosphere and from Earth-orbiting satellites, and also from the sun's radio noise, during the lunar night. And so, such a radio lunar-based telescope will enable tremendous scientific discoveries, for example, in the field of cosmology, by observing the early universe in this range of 10- to 50-meter wavelength span, which has been unexplored completely by humans to date.Is there any film that you think portrays what you do at all realistically? If the answer is no, what space, science-fiction movies do you find inspirational? I'm guessing maybe Contact, but maybe there are some others?Exactly. Contact inspired me when I was growing up for several reasons. I started during the holiday—but I didn't have the time to finish it—to watch Don't Look Up. But I watched the first half an hour, and I have to say that Leonardo DiCaprio was very much into the professor type. And so all the dynamics that happened had a scientific but also a bureaucratic level, so to say. But since we are talking about movies, a movie that I love, and it's really inspirational for very many points of view, is Interstellar. Many scientists will say that it’s a movie that is completely wrong and so forth. When I watch a movie, I like to watch a movie as a person detached from my scientific point of view, just because it's a movie and it's fiction. Many movies are completely untrue for several aspects, so why are we going to investigate how physically true it is? It’s a movie, right? We need to enjoy it.Americans’ enthusiasm for spaceWhen you're traveling and you tell people what you do, I imagine people are pretty enthusiastic, because my theory is that people are super interested if we popularize and we let people know what actually is happening. There's been a lot happening other than Moon landings over the past half century, and maybe a lot more happening over the next 10 or 20 years.Absolutely, yeah. I completely agree with you. When I travel and I get to speak with people and “What do you do?” I say I'm an astrophysicist. It blows their mind just because people don't have any idea about actually what we do. They think that we look through a telescope. That’s part of what we do in the free time, maybe. But the reality is way beyond that. I believe space is such a source of huge inspiration for mankind, for all of us. And so it's definitely on us, the scientists, astrophysicis…

    On previous episodes of Faster, Please! — The Podcastand in my newsletter essays, I've argued for the importance of optimistic science fiction. But what exactly qualifies as future-optimistic fiction, and how is it different from utopian literature? To discuss one of my favorite science-fiction book and TV series, The Expanse, and to consider the importance of what fiction tells us about the future, I've brought on Peter Suderman.Peter is features editor at Reason magazine. He has written a number of fantastic pieces on science fiction including "The Fractal, Fractious Politics of The Expanse" in the December 2022 issue of Reason.In This Episode* Does The Expanse count as optimistic science fiction? (1:15)* Optimistic—not utopian—visions of the future (9:10)* The evolution of science fiction (19:30)* The importance of the future sci-fi shows us (27:09)Below is an edited transcript of our conversation.Does The Expanse count as optimistic science fiction?French film director François Truffautfamously claimed it was impossible to make an anti-war film. He said, “I find that violence is very ambiguous in movies. For example, some films claim to be antiwar, but I don't think I've really seen an antiwar film. Every film about war ends up being pro-war.” And that quote, which has always stuck in my head, reemerged in my brain when I came across a somewhat similar observation from Jurassic Park author Michael Crichton, who said, “Futuristic science fiction tends to be pessimistic. If you imagine a future that’s wonderful, you don’t have a story.” I think some people may interpret that as meaning you cannot write optimistic science fiction.And I think of a show that you have written a long essay about, and I've written about—not as intelligently, but I've written about it from time to time: the TV show The Expanse. And I find The Expanse to be optimistic sci-fi. It takes place in the future, a couple hundred years in the future. Humanity has spread out to Mars and the asteroid belts. There's certainly conflict. As an Expanse fan, someone just wrote an essay on it, would you agree that it’s optimistic science fiction?I think it is, with some caveats. The first one is that it's optimistic but it's not utopian. And I think a lot of the argument against optimistic science fiction is actually not really arguing against optimism. It's arguing against utopianism and this idea that you sometimes see—there are hints of it sometimes in Star Trek, especially in Star Trek: The Next Generation—of, in the future humanity will have all of its problems solved, we won't have money, there will be no poverty. If you think about the Earth of Star Trek: The Next Generation's future, it's actually kind of boring, right? There isn't a lot of conflict. Writers eventually found ways to drive conflict out of conflicts between the Federation and other planets and even within the Federation. Because of course, they realized the utopian surface is just a surface. And if you dig down at all beneath it, of course humans would have conflict.But I think a lot of the opposition to the idea of optimistic science fiction just comes from this idea of, “Well, wouldn't it be utopian?” And what The Expanse does is it tells a story that is, I think, inherently optimistic but really deeply not utopian, because it recognizes that progress is not an easy, straight linear line in which everybody comes together and holds hands, and there's a rainbow and My Little Ponies, and everybody just sort of sings, and it's wonderful. That's not how it works. In fact, the way that progress happens is that people have things they want in their lives, and then they seek, either on their own or in coalitions, factions, organizations—whether that's governments, whether that's the private sector, whether that's unions, whatever it is—they organize somehow or another to get the thing that they want. And sometimes they build things. Sometimes they build habitats.And so this is something you see a lot of in The Expanse. Humans have colonized the solar system, as the story begins, and there are just all of these fascinating habitats that humans have built. Some of those habitats actually have problems with them. There are air filtration issues, where you have to constantly be supplying ice from asteroid mining. That sort of thing. Some of the main characters, when we first meet them, are working as ice haulers. Because of course, you would have to have some sort of trade of important resources in space in order to make these habitats work. And you could call this, “That’s not optimistic. In fact, a lot of these lives are sort of grubby and unpleasant, and people don't get everything they want.” But I think that misunderstands the idea of progress, because the idea of progress isn't that suddenly everything will be happy and My Little Pony-ish. It's not My Little Pony. It's actually conflict and it's clashing desires and it's clashing ideals about how humans should live. And then it's people kind of working that stuff out amongst themselves, day by day, hour by hour, through coalitions, through organizations, through institutions, through technology, through politics sometimes. And all of those sort of tools and all of those organizational forms have a role. Sometimes they also have drawbacks. All of them have drawbacks to some extent. And then it's just a matter of how are people going work out the problems they have at the moment in order to get to the next place, in order to build the thing they want to build, in order to start the society they want to have.It's a six-season TV show based on a nine-novel series. The six-season TV show adapts the first six books, and then there are three additional books, plus there's a bunch of short stories, novellas, interstitial material. There's this moment that happens in both the TV show and in the books that's really important. And it's about it when humanity finds a way to other solar systems. There are 1300 gates that open up and they can sort of go out and colonize the rest of space. All of these colonies are settled, and each one of them takes on an idea and a culture and often technological capability. There's one of them that's really funny that you meet called Freehold. Frankly, it's a bunch of anarchist libertarian gun nuts who decide to basically ignore all the rules that the trade union that is managing a lot of the trade between the gates has put in place. And they are managing that trade for a good reason. Because if you mess with the gates, if you go through them the wrong way, it kills people, it kills ships, it destroys them. And so you have to go through in order, and you have to go through slowly, and it's this whole sort of process. In Freehold, they‘re a bunch of difficult, crazy anarchist-like libertarian gun nuts who don't want to play by the rules. And at first they're a problem. You can see why that would be a problem for the social organizational form that has come up in these books from managing the gates and making sure that they don't kill people. But later, when basically a super powerful high-tech imperial planet that has designs on controlling all of humanity and putting all of humanity under the thumb of basically one emperor who has plans to live forever—it's sort of this, become a kind of a god who is ruling over all of humanity and then basically turn all of humans into like a hive mind but for the good of humanity so that we'll survive—when you have that all-encompassing, super powerful collectivist impulse that is threatening human civilization, it turns out that the libertarian anarchist gun nuts at Freehold are actually pretty good friends to have. This series does a bunch of interesting work of noting that, yes, of course those people can be difficult at times, and they can present problems to social cohesion. At the same time, it's not bad to have them as allies when you are threatened by an authoritarian.Optimistic—not utopian—visions of the futureYou've nailed it. Well done. I view it as optimistic but not utopian—I think that's a key point—particularly compared to how the future is often portrayed. I think it's pretty optimistic because no zombies. We're still around. And the world looks like it's doing okay. Was there climate change? Sure. But New York is surrounded by barriers. Clearly there's been disruption, but we kept moving forward. Now we're this multi-planetary civilization, so it doesn't look like we're going to get killed by an asteroid anytime soon.I think a big mistake that a lot of the pessimists about the future in politics and our culture generally, but in science fiction as well—a big mistake that they make is that they think only in terms of grand plans. They think in terms of mass systems of social control and social organization. And so when you see an apocalypse, it's “all the governments have failed and so has capitalism.” When you see an apocalypse, it's “the oceans swallowed us because we used too much energy or the wrong kind of energy.” And that's it. The grand plan didn't work. And then we're in a hellscape after that. And what you see in The Expanse, what makes it so smart, is grand plans actually do fail.Almost any time somebody has a big sweeping theory of how we're going to reorganize human social organization, of how humanity is going to be totally different from now on—almost anytime that someone has that sort of theory in The Expanse series, it doesn't work out. And often that person is revealed to be a bad guy, or at least somebody who has a bad way of thinking about the world. Instead, progress comes in fits and starts, and it's made on a much smaller scale by these ad hoc coalitions of people who are constantly changing their coalitions. Sometimes you want something that requires building something, that requires a new technology. And so you ally with people who are engineer types, and you work with them to build something. At the end of it, you've got the thing that they've built, and your life is a little bit better, or at least you've accomplished one of your goals. And then maybe after that, those people, the engineers, actually it turns out that they have a culture that is not cooperative with yours. And so you're going to ally with a different political faction and the engineers are going to be on the other side of it, but they've still built the little thing that you needed them to build. And it's just this idea that big systems and big plans that assume that everything falls in line, those plans don't work, and they do fail. And if that's your idea of how we're going to make progress, that's a bad idea. The way we make progress is…In a Hayekian sense, all our individual wants and needs cannot be incorporated in this grand system or grand plan. Our wants and needs today, much less how those will evolve over time. Our future wants and needs don't fit into the plan either.Yeah, this is right. This is one of the issues I have with a lot of zombie fiction, is that it just sort of assumes that after the zombie apocalypse—the zombie apocalypse is not all that realistic, but you can imagine a scenario in which there is something environmental that really goes very bad for humanity; that's not out of the realm of possibility—but what a lot of the zombie apocalypse fiction assumes, then, is that in the decades or years afterwards no one will really find ways to work with other people towards shared goals. Or at best, they'll do so in a really ugly and simplistic way where somebody sets up a society that's walled off but it's ruled by some evil authoritarian and you're living under this person's thumb.I grew up in Florida, and so we had hurricanes. One of the things you see when you have hurricanes is that, yes, there is a government response and they send out trucks and power company officials and all of that sort of thing. But people drive around the neighborhood with chainsaws and cut up the trees that have fallen across your driveway. And other people who may not have chainsaws go and help their friends move the stuff out of their bedroom where the tree fell into the bedroom through the ceiling and there's been some leakages. It's just sort of people working together in these informal coalitions, these little neighborhood local groups, to help each other out and to try to fix things that have broken and gone wrong. It’s not fun. It’s not like, “Oh man, hurricanes, they're wonderful. We shouldn't worry about them at all!” We should, and we should try to build resilience against them and that sort of thing.At the same time, when disaster strikes, often what you see—not always, but often what you see—is that people come back together and they survey the problems and they work to fix them minute by minute, hour by hour in little ways. And sometimes the first thing you do is, “Well, I got a hole in my roof. I'm going to stretch garbage bags across it so that the next time it rains…” And then you got a hole in your roof with garbage bags across it for a couple of weeks. But that's a solution for the time. It's better than a hole in your roof. On the other hand, you got a hole in your roof. It sucks. But that's progress relative to the hole that's there. That’s a way that a lot of people who don't think about engineering, who don't think in a Hayekian manner, it's something that they miss. Because they only think about big systems and big plans. And big systems and big plans do have big risks, and they do often fail. But that's not how humans figure out how to move forward and how to make their life better.An interesting aspect is that, you mentioned how at some point these gates open so we're no longer stuck in the solar system. We can go to any of these other planetary systems. And what's interesting is the devastating effect this has on the planet Mars, which is its own world, its own government, it has its own military, it's independent of Earth. But it's a society that was built around one big idea, which is terraforming Mars and creating a sustainable civilization. And when that goal didn't look important anymore, that was it. It fell apart. People left. There was no resilience, there was no ability to adapt. To me, that's one of the most interesting twists I've seen in science fiction. When the grand plan fails, the whole thing falls apart because they never assumed the grand plan wouldn't work.The Mars example is great because it shows what I think is one of the biggest problems in political thinking and in kind of bad science-fiction storytelling. It's a great demonstration of steady state thinking, where people think that the current arrangement of power and resources is going to persist forever. And so Mars in The Expanse story was basically a competitor with Earth, which in The Expanse universe was the sort of political home of humanity as well as the bread basket. It's where of all the food was produced. And then the asteroid belt, which is sort of the rough and tumble outer world—the outer world were the resource extractors. They provided for the inner systems. They kind of had a blue-collar vibe to them. There was some terrorist activity that came out of this because they were resentful. There's sort of some interesting cultural and subcultural effects there. And then Mars was heavily military and high tech, and they thought that would be their competitive advantage.Almost a quasi-fascist state, in a way. It was very militari…

    If humanity is to become a multi-planetary species, we can't forever remain dependent on Earth's resources. That's where space resource extraction comes in. So how would space mining work, what problems would it solve, and how long will we have to wait? To answer those questions, I'm joined in this episode by Kevin Cannon. Kevin is a professor of space resources and geology and geological engineering at Colorado School of Mines in Golden, Colorado. He's also author of the Planetary Intelligence newsletter on Substack.In This Episode* How mining in space could benefit Earth (1:13)* The basic economics of space mining (3:56)* Space resources and multi-planetary civilization (9:32)* Public and private sector space exploitation (14:00)* The next steps for space resource extraction (17:56)* The criticisms and hurdles facing space mining (26:15)Below is an edited transcript of our conversation.How mining in space could benefit EarthJames Pethokoukis: You've written that building a space-based civilization is all about raw materials. Given your academic specialty, these are raw materials out there, not down here. But if I am not interested in building a space-based civilization, do I care what's out there, what materials, what elements I can find out there?Kevin Cannon: Let me give you two examples of how this could kind of come back to Earth. One is something that's being talked about increasingly lately, and that's this idea of space-based solar power. We want to undergo this energy transition, switch to renewables. Solar power, the issue there is the scaling and the land that's available. You only have so much land that you can put up more solar panels on. So if we wanted to have a truly energy-abundant future, one way to do that is to actually put up structures, satellites, in orbit that collect solar power and beam it back to the Earth via microwaves. And it turns out the only way to really make this economic is to actually make those structures out of raw materials that are found in space, either from the Moon or from asteroids. If you try to launch everything that you need, it's just too expensive. It's too difficult. So that's one example.A second example related to that, there's obviously a lot of talk about climate in general, and there's still this idea out there that we can get through this climate issue by just reducing emissions. I think at a higher level, the discussions out there are that that's not going to be enough, that we're not drawing down those emissions fast enough, and that we may need to use different geoengineering techniques. There are different ways to do that. You can inject stuff into the atmosphere. You can put stuff into the ocean. Those are a little bit problematic politically. One alternative is to actually just block out a small fraction of the sun's radiation with something called a planetary sun shade. You put up a structure in space at the L-1, the Lagrangian point between the sun and the Earth, and that structure blocks out, say, 1 to 2 percent of the sunlight and cools the planet and helps as a mitigation effort. And again, that structure is so large that we could not possibly launch that into the space. We would have to build that out of materials that we find. So even if you don't want to leave the Earth, you're happy here, you still have problems on Earth. And there are solutions to those that could potentially be found by using raw material on the Moon or on asteroids.The basic economics of space miningYou're saying that even with the decline we've seen in launch costs in recent years, and even assuming some continued progress, it would be more affordable to build these two examples with the regolith — or the surface dirt from the Moon or Mars or from some other place, some asteroid — than just getting it out into space with a rocket, even if it's a rocket that goes up pretty cheaply compared to the rockets of the past.The thing you have to understand is that as those launch costs come down, it also becomes cheaper to put the factory on the Moon that makes the components, that assembles the structure in space. And it's also the case that we wouldn't build 100 percent of the structure. You would still be launching the intricate parts, the dopants for your solar panels, the wiring, things like that. It's kind of the bulk structure that we would make, what we call the “dumb mass” as opposed to the “smart mass.” But yes, as the launch costs come down, it's easier to put things in orbit, but it's also easier to put construction material and assembly material to do this kind of space-based construction effort.That’s always the big concern: trying to make the economics work. I find that people aren't fully aware of what possibilities have been opened up because it's gotten a lot cheaper to launch rockets into space. And hopefully it will get a bit cheaper still.We're anticipating right now in the months ahead, the first orbital launch of the SpaceX Starship. SpaceX has brought the launch costs down dramatically just with the Falcon 9, through reuse, through the Falcon Heavy. But the possibility for Starship is really a step function. It's not just a continuation of that smooth decline, but really a potential leap in our ability to put massive amounts of stuff into space. If that design is proved out, then hopefully other competitors will start to copy that and improve on it and we'll see an even more dramatic reduction.People have a hard time understanding the economics of going and mining an asteroid to bring back to build things on Earth. Would that be economical versus using that material to build things out in space?There's only a very narrow case you could make for a certain class of materials. And specifically, that would be things like the platinum-group metals. Those meet a number of criteria: They're very expensive — for example, the metal rhodium sells for about $400,000 per kilogram — and we only mine a very small amount of those per year. It's measured in single-digit or double-digit tons: 20 or 30 tons of these materials per year. Possibly, you could make an economic case to bring back some of those platinum-group metals. But for something like copper, we mine millions of tons per year, and that's never going to make sense. That's kind of the big misnomer about space resources that's out there in the public perception: that what we're talking about is going out into space and bringing stuff back and selling it into existing commodity markets. And that's really not what the main focus is. The main focus is using local materials that we find to help expand civilization into space rather than bringing everything with us. But maybe, just maybe, you could make a case for something like some of these platinum-group metals.What you're doing is not speculative. This is something that you think will have practical application and you're graduating students who are getting hired to begin to think and do this, right?It's still in the early stages, but it's not science fiction and it's not theoretical. Let me give you a couple examples of what's been happening in the last few years. Last year on Mars, there's a small instrument on board the Mars Perseverance rover, the NASA rover, called MOXIE. And this is a demonstration that sucks up a little bit of the CO2 atmosphere of Mars and converts it into breathable oxygen. This is the first time in history we've taken a raw material on another planetary body and actually turned it into a valuable product. It's the first creation of a resource in space.Second example: A couple months ago, we had the launch of a private lander from the company ispace. This is going to be the first attempt at a commercial landing on the Moon. And as part of that mission, they're going to try to scoop up a small amount of the regolith. And NASA has already signed a contract to purchase that material. It's a very small dollar amount. The real point of that is to set a precedent that if you go out and mine material in space, that it is yours to then sell to someone else. So if that's successful, around April that will be the first sale of a resource in outer space. There are a wide variety of companies working on this. We have the Space Resources Program at Colorado School of Mines. And just an example there, Blue Origin — not a lot of people know about this — in the past year or so they've hired about 30 full-time employees working just on space resources [in situ resource utilization].Space resources and multi-planetary civilizationAs you've been talking, I've been trying to quickly dig up a quote from one of my favorite books and TV shows, The Expanse, which touches on this issue of the resources out there. Let me just quickly read it to you: “Platinum, iron, and titanium from the Belt. Water from Saturn, vegetables and beef from the big mirror-fed greenhouses on Ganymede and Europa, organics from Earth and Mars. Power cells from Io, Helium-3 from the refineries on Rhea and Iapetus. A river of wealth and power unrivaled in human history came through Ceres.” That’s the big sci-fi dream, that there is this vast field of resources out there that we can tap into. And if we can tap into it, it will be primarily for creating this space civilization.Yeah, that's exactly right. The atoms are out there. We know all of the atoms in the periodic table are found on every planetary body. It's a matter of concentration, and it's a matter of having the energy to separate those out and turn them into useful products. As long as we can figure out how to do that, then we have the resources available, just in the solar system, to support a massive population of people to live at a very high level of well-being. The long-term promise is that we can expand into space and have a thriving civilization that is built on top of those resources.I love how you put it in one of your tweets. You wrote, “Space resources are optional to gain a foothold in space, but necessary to gain a stronghold.”If you look back at what we've done so far in human space exploration, we've landed 12 people on the Moon, they walked around for a few days, and then they came back. Since then, we've sent people up to low-Earth orbit to the International Space Station or the Chinese equivalent. They stay up there for a few months, and they come back. In those cases, it makes sense to bring everything that you need with you: all the food, all the water, all the oxygen. If we have greater ambitions than that, though — if we want to not just walk around on the Moon, but have a permanent installation, we want to start growing a city on Mars that becomes self-sufficient, we want to have these O'Neill cylinders — you simply just can't launch that material with you. And that's because we live in this deep gravity well. We can just barely get these small payloads off the surface with chemical rockets. It just economically, physically does not make sense to try to bring everything with you if you have these larger ambitions. The only way to enable that kind of future is to make use of the material that you find when you get to your destination.The question I always get is, why bother doing any of this? Is that a question you spend a lot of time trying to answer? Or are you convinced it's going to happen and you've just moved beyond the question?I think enough people have made the case for why we need to do this. You can look at it from different perspectives, from one of scientific discovery to one of existential risk to the planet that, if we stay here on Earth, eventually something is going to come along that presents an existential risk to civilization. What I'm trying to do is work with the people, with the companies who are actually trying to do this and help them using my perspective, this kind of unique perspective that's based around the science and the composition of these planetary bodies and how to make use of these resources. I don't concern myself too much with the question of why we should do that. I'll kind of leave that to more of the philosophers, the other people who have worked on that. I agree that I'm kind of past that and I am really deep in the nitty-gritty details of how to actually do this: how to turn the regolith into metals and ceramics; how to get rocket propellant out of ice at the pools of the Moon. That's what I spend my time focused on.Public and private sector space exploitationThere was a boom in some planetary resource startups a few years ago which didn't last. What has changed between now and back then? Is it just the drop in launch costs? The technology has gotten better? Up until very recently, we had very low interest rates, it was easy to finance things? We're in like a second wave of this. What is making this second wave possible?I think the launch costs and technology do make a difference. I think the other thing is the way that some of these newer companies are going about it. That first wave that started back around 2012, you had these two main companies, Planetary Resources and Deep Space Industries, and they tried to do this as kind of a typical venture capital–funded endeavor where they went through their seed round, their series A, series B. And that's pretty difficult to do if you want a return on your investment in five to seven years. So what we're seeing lately are companies coming into this space who have already amassed a lot of capital. They might have founders or backers who have the money to actually put up missions without first raising capital.I think that's what's going to start to make more of a difference and make this second wave last and have longer legs. Some of the companies that are coming into this: I mentioned one, of course, Blue Origin with Jeff Bezos, who is pumping in about a billion dollars a year, very active in this space, not talking about it a lot publicly. But there are some newcomers that have also shown up in the last couple of years. One that we're working with is called KarmanPlus. They are a new asteroid mining company who are going to be setting up shop here in Colorado. They have the money upfront to be able to make a splash without having to go through the typical kind of VC funding route at the very beginning.How supportive is NASA of this general concept of seeing space as a resource to be extracted or exploited, whether it's to do things here on Earth or build a space civilization? Are they all on board? Do they view this as, “This is a private sector thing; we're going to focus on exploration and doing science, and this is a different thing and we really don't care”?NASA historically has always put a little bit of money into this field and the field of space resources. They have kept it going even as interest has waxed and waned. What they've never done, though, is made it a critical part of their missions. For example, right now they're working towards the Artemis program: landing people back on the surface of the Moon. They're exploring ideas of prospecting for ice at the poles of the Moon. They have this upcoming VIPER mission. They're funding technology to extract oxygen from the lunar regolith. But what they're not doing is saying the Artemis astronauts are going to breathe that oxygen and that's going to be a critical part of the Artemis program. So they're funding it; they're bringing it along. They are supporting it to some extent, but they're not making it a key part of their missions. I think what we're going to see is continued activity i…
