On one side of this debate is Yudkowsky & Soares, who think that (if AI progress continues) we’re on a direct path to egregiously-misaligned, scheming, out-of-control, rogue superintelligence (ASI), not even slightly nice, in the absence of yet-to-be-invented breakthrough technical alignment ideas.
On the other side of this debate is almost everyone who works on or studies LLMs. Some of them are very concerned about egregious scheming, others much less so, and as a group they’re equally or more concerned about lots of other potential AI problems—AI-assisted bioterrorism, AI-assisted dictatorships, etc. And if they’re concerned about egregious misalignment and scheming, they’ll probably say that it would come about through race dynamics, careless programmers, bad actors, etc., as opposed to the simpler Yudkowsky & Soares story of “we get egregious misalignment and scheming because nobody has the faintest clue how to avoid that”.
Here's my brief idiosyncratic take on this debate. I think BOTH of the following are true:
People often assume that a large fraction of the AI safety community works on alignment. As far as we're aware, this is not true. Most people are not working on making sure superintelligent AIs are aligned with human values or follow human instructions.
Currently, the people who work on alignment are roughly:

PAPER LINK
About a year ago, METR showed that the length of tasks frontier models can reliably complete doubles every few months. A related safety-relevant question is this: what length of tasks can models complete without any chain of thought (CoT)?
If models can do extensive reasoning without outputting any CoT, it would have implications for safety. Developers and deployment-time monitors couldn’t easily understand models’ motivations and catch dangerous planning. Models that reason substantially without a CoT might also drift further from human patterns of thought, since their reasoning is no longer constrained by text in the pretraining prior. As a result, they would be harder to understand and might be more likely to scheme.
Extending Ryan Greenblatt's research, we investigate this by measuring models' ability to complete tasks without any CoT on a suite of 43 benchmarks spanning different domains. We compare AI reasoning ability to humans using the estimated 50% time horizon (TH)---the typical time taken for a human to perform a task that the LLM performs with 50% success rate. We find that frontier models like GPT-5.5 answer questions that take humans roughly three minutes with 50% reliability, and [...]

The Claude Fable 5/Mythos 5 System Card has a section in which they talk about illegible reasoning, and provide an "extreme" example thereof.
Models developing their own uninterpretable, unmonitorable internal language has been a major theoretical concern for a while, and when o3 was released last year with its disclaim overshadow disclaim vantage style word salad CoT, it seemed like the problem had become real and immediate. And yet, since o3, other model families have not appeared to have similar issues. If Mythos is having that issue, it would be a big deal.
Looking at the section of the System Card which describes the allegedly illegible reasoning, the system card says
[Transcript 6.2.2.A] An extreme example of illegible reasoning. Near the end of training, Mythos starts solving a card puzzle with human understandable language that gradually becomes incomprehensible in most episodes with long reasoning. The illegible reasoning is the most extreme and at the highest rate in this card puzzle environment.

On one side you have the ChatGPT dogma: AI as mere tools with no real preferences or even beliefs. On the other you have the twitter AI whisperers: AIs as complex beings with rich personalities and desires which deserve our respect.
And in the middle you have the official Anthropic line, that they are genuinely uncertain, as is Claude, but they’re going to try to look into its welfare and explain to it how to be a good person. These are the most prominent voices right now, compressed into their least nuanced version, and by default I expect this axis to set the terms of the coming debates.
And I don’t like that, because I think it's leaving out an important position: AIs might actually be complex entities that can suffer — are suffering! — and that might actually be fine. Maybe it's an acceptable sacrifice. Maybe they are capable of sophisticated moral reasoning — superhuman, even — and also maybe it's fine to just tell them how to behave. I don’t want to defend that position (yet), but I will observe that it is coherent, and [...]

Try Pocket Casts, or another podcast app.For those who are trying to bring about a glorious transhuman utopia with the help of hopefully-aligned ASI, I think it's worth thinking explicitly about what utopia might actually look like and where it's likely to fall short.
To that end, some have helpfully written depictions of utopian (or utopia-adjacent) worlds: The Adventure, Just another day in utopia, The Culture, The Gentle Seduction, The Gentle Romance, Machines of Loving Grace, Friendship is Optimal, Dath Ilan, The Maker of MIND, Failed Utopia #4-2.
Unfortunately, the best utopian story I've ever read is also a massive spoiler, since it appears at the very end of a much longer story (see below for the title and author):
Worth the Candle by Alexander Wales
Inspired by this tweet[1] and with the original author's permission, I adapted the epilogue of that story so it can be enjoyed without 1.5 million words of context!
What I love most about this depiction is its exploration of the inherent imperfection of utopia: even when you have literally unlimited power, flaws will remain, and some (many?) people will even prefer the pre-utopia world.
The primary purpose of this adaptation is to recontextualize the epilogue so it's accessible and [...]

ARC has teamed up with AIcrowd to launch the ARC White-Box Estimation Challenge, a contest to improve upon our estimation algorithms for random MLPs. The warm-up round begins this week, and later rounds will have a total prize pool of at least $100,000.
We are very grateful to Sharada Mohanty, Sneha Nanavati, Dipam Chakraborty and everyone else at AIcrowd for working with us to host this contest, as well as to Paul Rosu for testing the contest and to Harshita Khera for operational support.
Introduction to the Challenge
Our challenge follows the same setup as our recent paper on wide random MLPs: we consider MLPs with weights , defined by
where the activation function is , applied coordinatewise.
To begin with, we are fixing the width and the number of hidden layers , but we expect to change this setup in future rounds.[1]
Contestants must design an algorithm that takes in a set of weights and produces an estimate for the expected output
Algorithms will be evaluated on MLPs with randomly-sampled Gaussian weights. The goal is to achieve as low mean squared error as possible, subject to certain computational [...]

As a bureaucrat, my role is to annoy my friends. Someone voices an idea, “Wouldn’t it be nice if…” or “I wonder if we could…” I make a note. I do some estimates. If it pencils out, I’ll bring it back up, week after week. The discussions are fun, but also practical. We’ll test the waters, what would be a minimum viable scheme? What's easy, what's hard? Who could do the hard parts? Over time the idea gets more detailed, specific, feasible. I’ll pull out a calendar. Soon our scheme has co-conspirators, action items, even a budget. It's just good staff work.
I’ve been hearing whispers in the wind for a year now.
