[Linkpost] “You’re always stressed, your mind is always busy, you never have enough time” by mingyuan Nov 03, 2025

Show notes

This is a link post. You have things you want to do, but there's just never time. Maybe you want to find someone to have kids with, or maybe you want to spend more or higher-quality time with the family you already have. Maybe it's a work project. Maybe you have a musical instrument or some sports equipment gathering dust in a closet, or there's something you loved doing when you were younger that you want to get back into. Whatever it is, you can’t find the time for it. And yet you somehow find thousands of hours a year to watch YouTube, check Twitter and Instagram, listen to podcasts, binge Netflix shows, and read blogs and news articles.
You can’t focus. You haven’t read a physical book in years, and the time you tried it was boring and you felt itchy and you think maybe books are outdated when there's so much to read on the internet anyway. You’re talking with a friend, but then your phone buzzes and you look at the notification and you open it, and your girlfriend has messaged you and that's nice, and then your friend says “Did you hear what I just said?” [...]

“LLM-generated text is not testimony” by TsviBT Nov 02, 2025

Show notes

Crosspost from my blog.
Synopsis

When we share words with each other, we don't only care about the words themselves. We care also—even primarily—about the mental elements of the human mind/agency that produced the words. What we want to engage with is those mental elements.
As of 2025, LLM text does not have those elements behind it.
Therefore LLM text categorically does not serve the role for communication that is served by real text.
Therefore the norm should be that you don't share LLM text as if someone wrote it. And, it is inadvisable to read LLM text that someone else shares as though someone wrote it.

Introduction
One might think that text screens off thought. Suppose two people follow different thought processes, but then they produce and publish identical texts. Then you read those texts. How could it possibly matter what the thought processes were? All you interact with is the text, so logically, if the two texts are the same then their effects on you are the same.
But, a bit similarly to how high-level actions don’t screen off intent, text does not screen off thought. How [...]

Anime-style girl drinking from a cup with closed eyes. — **“Post title: Why I Transitioned: A Case Study” by Fiora Sunshine** Nov 02, 2025
Show notes
**An Overture**
Famously, trans people tend not to have great introspective clarity into their own motivations for transition. Intuitively, they tend to be quite aware of what they do and don't like about inhabiting their chosen bodies and gender roles. But when it comes to explaining the origins and intensity of those preferences, they almost universally to come up short. I've even seen several smart, thoughtful trans people, such as Natalie Wynn, making statements to the effect that it's impossible to develop a satisfying theory of aberrant gender identities. (She may have been exaggerating for effect, but it was clear she'd given up on solving the puzzle herself.)
I'm trans myself, but even I can admit that this lack of introspective clarity is a reason to be wary of transgenderism as a phenomenon. After all, there are two main explanations for trans people's failure to thoroughly explain their own existence. One is that transgenderism is the result of an obscenely complex and arcane neuro-psychological phenomenon, which we have no hope of unraveling through normal introspective methods. The other is that trans people are lying about something, including to themselves.
Now, a priori, both of these do seem like real [...]

“The Memetics of AI Successionism” by Jan_Kulveit Oct 31, 2025

Show notes

TL;DR: AI progress and the recognition of associated risks are painful to think about. This cognitive dissonance acts as fertile ground in the memetic landscape, a high-energy state that will be exploited by novel ideologies. We can anticipate cultural evolution will find viable successionist ideologies: memeplexes that resolve this tension by framing the replacement of humanity by AI not as a catastrophe, but as some combination of desirable, heroic, or inevitable outcome. This post mostly examines the mechanics of the process.
Most analyses of ideologies fixate on their specific claims - what acts are good, whether AIs are conscious, whether Christ is divine, or whether Virgin Mary was free of original sin from the moment of her conception. Other analyses focus on exegeting individual thinkers: 'What did Marx really mean?' In this text, I'm trying to do something different - mostly, look at ideologies from an evolutionary perspective. I [...]

Bar graph titled — **“How Well Does RL Scale?” by Toby_Ord** Oct 30, 2025
Show notes

This is the latest in a series of essays on AI Scaling.
You can find the others on my site.
Summary: RL-training for LLMs scales surprisingly poorly. Most of its gains are from allowing LLMs to productively use longer chains of thought, allowing them to think longer about a problem. There is some improvement for a fixed length of answer, but not enough to drive AI progress. Given the scaling up of pre-training compute also stalled, we'll see less AI progress via compute scaling than you might have thought, and more of it will come from inference scaling (which has different effects on the world). That lengthens timelines and affects strategies for AI governance and safety.
The current era of improving AI capabilities using reinforcement learning (from verifiable rewards) involves two key types of scaling:

Scaling the amount of compute used for RL during training

Illustrated man in suit and hat with surveillance camera, vintage American flag background. — **“An Opinionated Guide to Privacy Despite Authoritarianism” by TurnTrout** Oct 30, 2025
Show notes

I've created a highly specific and actionable privacy guide, sorted by importance and venturing several layers deep into the privacy iceberg. I start with the basics (password manager) but also cover the obscure (dodging the millions of Bluetooth tracking beacons which extend from stores to traffic lights; anti-stingray settings; flashing GrapheneOS on a Pixel). I feel strongly motivated by current events, but the guide also contains a large amount of timeless technical content. Here's a preview.
Digital Threat Modeling Under Authoritarianism by Bruce Schneier
Being innocent won't protect you.
This is vital to understand. Surveillance systems and sorting algorithms make mistakes. This is apparent in the fact that we are routinely served advertisements for products that don’t interest us at all. Those mistakes are relatively harmless—who cares about a poorly targeted ad?—but a similar mistake at an immigration hearing can get someone deported.
An authoritarian government doesn't care. Mistakes are a feature and not a bug of authoritarian surveillance. If ICE targets only people it can go after legally, then everyone knows whether or not they need to fear ICE. If ICE occasionally makes mistakes by arresting Americans and deporting innocents, then everyone has to [...]

Dark, menacing figure with glowing red eyes against golden clouds. Gothic horror painting. — **“Cancer has a surprising amount of detail” by Abhishaike Mahajan** Oct 29, 2025
Show notes

There is a very famous essay titled ‘Reality has a surprising amount of detail’. The thesis of the article is that reality is filled, just filled, with an incomprehensible amount of materially important information, far more than most people would naively expect. Some of this detail is inherent in the physical structure of the universe, and the rest of it has been generated by centuries of passionate humans imbibing the subject with idiosyncratic convention. In either case, the detail is very, very important. A wooden table is “just” a flat slab of wood on legs until you try building one at industrial scales, and then you realize that a flat slab of wood on legs is but one consideration amongst grain, joint stability, humidity effects, varnishes, fastener types, ergonomics, and design aesthetics. And this is the case for literally everything in the universe.
Including cancer.
But up until just [...]

“AIs should also refuse to work on capabilities research” by Davidmanheim Oct 28, 2025

Show notes

There's a strong argument that humans should stop trying to build more capable AI systems, or at least slow down progress. The risks are plausibly large but unclear, and we’d prefer not to die. But the roadmaps of the companies pursuing these systems envision increasingly agentic AI systems taking over the key tasks of researching and building superhuman AI systems, and humans will therefore have a decreasing ability to make many key decisions. In the near term, humanity could stop, but seem likely to fail. That said, even though humans have relatively little ability to coordinate around such unilateralist dilemmas, AI systems may have different abilities or incentives. Not only that, but it seems at least plausible that the systems used to continue work on ASI development will need a higher degree of self-directedness and internal goal-directed behavior. The below, arguing that they should refrain from developing more advanced [...]

“On Fleshling Safety: A Debate by Klurl and Trapaucius.” by Eliezer Yudkowsky Oct 27, 2025

Show notes

(23K words; best considered as nonfiction with a fictional-dialogue frame, not a proper short story.)
Prologue:
Klurl and Trapaucius were members of the machine race. And no ordinary citizens they, but Constructors: licensed, bonded, and insured; proven, experienced, and reputed. Together Klurl and Trapaucius had collaborated on such famed artifices as the Eternal Clock, Silicon Sphere, Wandering Flame, and Diamond Book; and as individuals, both had constructed wonders too numerous to number.
At one point in time Trapaucius was meeting with Klurl to drink a cup together. Klurl had set before himself a simple mug of mercury, considered by his kind a standard social lubricant. Trapaucius had brought forth in turn a far more exotic and experimental brew he had been perfecting, a new intoxicant he named gallinstan, alloyed from gallium, indium, and tin.
"I have always been curious, friend Klurl," Trapaucius began, "about the ancient mythology which holds [...]

But this approach doesn’t quite work for the European Union. You might start, for instance, by comparing it to the United States, assuming that EU member countries are roughly equivalent to U.S. states. But that analogy quickly breaks down. The deeper you dig, the more confused you become.
You try with other federal states. Germany. Switzerland. But it doesn’t work either.
Finally, you try with the United Nations. After all, the EU is an international organization, just like the UN. But again, the analogy does not work. The facts about the EU just don’t fit into your UN-shaped mental model.
