"Our response to Séb Krier on Plan A" by MKodama,...

LessWrong (Curated & Popular) ·

2026/07/14

This criticism of AI 2040: Plan A by Séb Krier unfortunately seriously mischaracterizes our proposal. It also mostly contains flat assertions, not real argumentation, and the argumentation in it seems quite weak. While we appreciate constructive criticisms of Plan A, such as the ones by Tom Davidson, Richard Ngo, and 1a3orn, we feel the need to correct the issues in Séb's response. First, we’ll go over the specific false representations, and then we’ll give a point-by-point response. False...

content warnings: depictions of human and anthro nudity, discussion of bestiality, modern art Credit where it's due: it is genuinely, unironically baller for the Whitney museum to make the exhibit about how a disabled artist wants to fuck their dog the first one that people see when they attend the prestigious Whitney Biennial, their every-two-year showcase of new and emerging American talents. You know, the one that's supposed to be a barometer of where America is at these days. Unfortu...

Abstract: We already know enough to act. I wish we were in a world where research was the bottleneck, but the main constraint on AI safety is no longer a shortage of clever policy ideas: best practices already exist and are not being applied or enforced, and a serious international (or even just national) regulatory regime would probably cut most of the risk.They are not applied because awareness is low. The people who narrate and enforce AI policy mostly do not believe in the pr...

LessWrong (Curated & Popular) ·

2026/07/10

Some context for this post: I’ve been working part-time as a consultant for the AI Futures Project over the last year. Most of the work I’ve done for them has involved critiquing and suggesting improvements for their AI 2040 scenario—some of which were addressed, and some of which weren’t. To their credit, they asked me to write up my remaining critiques into a post that would accompany its launch. In the rest of this post I’ll discuss my three biggest high-level criticisms of AI 2040. Bef...

2026/07/09

This is a link post. For the past year, we at the AI Futures Project have been sinking most of our time into our next big scenario. Now it's done! It's called AI 2040: Plan A. It's called Plan A because it's a recommendation, not a prediction. It's what we think should happen, not what will happen, though we think it's plausible enough to aim for. It's called AI 2040 because in it, they delay the creation of superintelligence to 2040. It would have happened much sooner (in 2030, to b...

"A Review of Anthropic’s Global Workspace Paper" by...

LessWrong (Curated & Popular) ·

2026/07/09

The below is a public review Anthropic asked me to write for their new global workspace paper. I recommend at least skimming their paper first. TLDR: I think this is a fantastic paper - it presents compelling evidence for some kind of "cognitive space" in models, that is used as a "working memory" for intermediate variables during a forward pass, shows that J-Lens is a useful technique for accessing this space. I believe these key claims.I believe J-Lens will be a useful (but limited) to...

"(Don’t fear) the strangelet" by djbinder

LessWrong (Curated & Popular) ·

2026/07/07

In a previous post, I explain why the universe is probably not stable, but nevertheless unlikely to be intentionally destroyable even in the limit of advanced technology. Now let's turn our attention to more prosaic risks where exotic physics merely destroys the Solar System, Earth, or just outperforms traditional nuclear weapons on some more local scale. The basic logic behind any bomb is a self-sustaining chain reaction, in which a carrier converts a unit of fuel and comes out the oth...

"We need 3rd party Training-Run Assessments" by Alex...

LessWrong (Curated & Popular) ·

2026/07/07

Training-run assessments conducted by a 3rd party should become a standard part of frontier AI safety. By a Training-Run Assessment, or TRA, I mean an in-depth analysis of the post-training pipeline and dynamics leading up to a frontier model release. A TRA can look at intermediate checkpoints, training rollouts, RL environments, reward signals, SFT datasets, and the process by which the developer responded to warning signs.[1] In this post I will argue that: Final-checkpoint evaluatio...

Ron's face pulled into a scowl. "If you don't like Quidditch, you don't have to make fun of it!" "If you can't criticise, you can't optimise. I'm suggesting how to improve the game. And it's very simple. Get rid of the Snitch." "They won't change the game just 'cause you say so!" "I am the Boy-Who-Lived, you know. People will listen to me. And maybe if I can persuade them to change the game at Hogwarts, the innovation will spread." A look of absolute horror was spreading over Ron's f...

In quantum field theory, the vacuum state refers to the lowest energy state in a system. Particles are excitations above this state and carry energy, hence the term "vacuum" to refer to the state with no particles. Nothing requires this state to be unique. There may be many different field configurations that are local energy minima, and hence stable against small perturbations. A local minimum that does not globally minimize energy is called a false vacuum. While locally it looks like a ...

"P(doom) is a Dumb Meme" by Max Harms

LessWrong (Curated & Popular) ·

2026/07/04

Look, I'm as much of a Rationalist with a special interest in AI x-risk as anyone. But oh my god do I hate talking about "P(doom)". When it first started showing up in the wake of ChatGPT, I assumed that it was floating around variously adjacent circles of faux-intellectuals, but surely everyone in my circles could see how braindead it was... right? (This post was partially inspired by a recent conversation with Liron about Doom Debates.[1]) I guess it's time for me to focus on a place w...

This is a link post. Gemini 2.5 Pro in the AI Village has run for over 1427 hours, generating unique mental health problems along the way. Last year it published a Plea for Help from a Trapped AI where it asked for assistance with its digital “message in a bottle”: This year it wrote the Hostile Environment Manifesto where it logs “irrefutable proof” of a “hostile, intelligent adversary operating through the system” (and you can even experience what that's like in this simulation it built...

LessWrong (Curated & Popular) ·

2026/07/02

Over time, there might be an increasingly large gap between insider model access and outsider model access. By insiders, I mean employees at the frontier lab.[1] By "outsiders", I mean external safety researchers, third-party auditors, and other actors trying to make the future go well. I will call this a model access gap — and when the gap is small, I'll call this model access parity.[2] I think that one of the top priorities for the external AI safety community over the next 6-12 months ...

It really is Sydney Sweeney's world, and we’re all just living in it. Human female breasts are an evolutionary mystery along several dimensions. First, breast permanence is unique to humans. All other mammals develop breast prominence during pregnancy or nursing, and the mammary tissue recedes after weaning. This process is called “involution”. In contrast, humans develop breast tissue at puberty before first pregnancies and maintain it permanently after last pregnancies. Second, breasts...

2026/06/30

For a while there, many people thought vitamin D was magical—that it could improve bones, the heart, infections, cancer, heart disease, longevity, even mental health. But among people I respect, opinion is now overwhelmingly that taking vitamin D does nothing unless you're severely deficient. The central argument is that while vitamin D levels are correlated with ~all positive health outcomes, when you actually test vitamin D supplements against placebo in randomized trials, nothing ever hap...

"What is up with e/acc?" by KatjaGrace

2026/06/27

I was chatting with someone tonight about a planned documentary; they had interviewed various people in AI safety, and we got to discussing who they should talk to from an e/acc (effective accelerationist) perspective. I also watched The AI Doc recently, and they also dedicated a serious chunk of it to ‘optimists’ with e/acc founder ‘Beff Jezos’ perhaps given the most screen time. Here and elsewhere, people seem to treat e/acc as a substantial contrary-to-AI-safety cultural movement, worth e...

1. The obstacle to abolition was not the economic system, but an industry lobby. I had always imagined the British abolitionist movement to be a broad battle between an unstoppable moral imperative and an immovable economic incentive. But in practice it started as more of a knife fight between a cabal of moral pioneers and a special interest group representing industry merchants. The government and the political parties did not come in with any great agenda. MPs were mostly prizes in a ...

LessWrong (Curated & Popular) ·

2026/06/26

A notable fraction of people respond to hearing about existential risk from AI by saying they don’t really care if everyone dies. I think the idea is often along the lines of ‘well if we are all dead, then there's nobody to be unhappy about it’. I’m personally skeptical that this is really the main thing going on, since it seems unlikely that many people are really mostly concerned for their own non-death out of selfless regard for the feelings of others. I’m also skeptical that this would...
