As you read this sentence, circuits in your brain are adjusting your posture, controlling your breathing, and transforming lines and curves on the screen into recognizable words. Most of this processing is invisible to you. But some of what takes place in your brain you do have access to—an image that pops into your head, or a deliberate plan you make about where to go shopping. Neuroscientists and philosophers sometimes refer to the latter type of brain activity as “consciously accessible,” to distinguish it from all the other processing that goes on unconsciously. This activity has special properties: we can describe it, control it, and use it for deliberate reasoning, in contrast to all the automatic processing that goes on without our awareness.

In a new paper, we present evidence that a similar distinction has emerged in modern language models like Claude. We find that Claude has developed a small collection of internal neural patterns that, compared to all its other internal processing, play a [...]

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 face. "But, but if you get rid of the Snitch, how will anyone know when the game ends?"

"Buy... a... clock. It would be a lot fairer than having the game sometimes end after ten minutes and sometimes not end for hours, and the schedule would be a lot more predictable for the spectators, too." Harry sighed.

Ron reached into his bag and pulled out a bottle of Wit-Sharpening Potion. His mother made it for him in case of an emergency, and this felt like an emergency. He didn't know a lot of things but he knew someone had to speak for Quidditch. For the Seeker and the Bludgers and [...]

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 stable vacuum, it is unstable and will decay to the deeper, true vacuum. If the energy barrier between the false and true vacuum is high, however, then the decay rate is exponentially suppressed and the false vacuum may be very long-lived.

Analogous behavior is common in other physical systems. Open a carbonated drink and the CO₂, more stable as a gas once the pressure is released, comes out as bubbles. But the bubbles take a moment to appear, and they form on the sides of the bottle rather than throughout the liquid. A bubble has to pay an energy cost to create its surface—the boundary between gas and liquid—and small bubbles have a larger surface-to-volume [...]

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 where I'm shocked that everyone else is dropping the ball.[2]

P(doom) is Hopelessly Vague

Let's start with the ambiguity. Does "doom" mean... extinction? A lot of people think so! I have personally encountered people who think catastrophic harms from AI are likely, but the risks of all humans dying are low. They're like "Sure, 99.999% of humans might die from AI, but the AI will obviously want to keep thousands of humans alive for science and potential trade with aliens and stuff, so my P(doom) is approximately 0%."

That might sound crazy. Surely you, dear reader, know exactly what "doom" means. You know, for example, which of these count as doom and [...]

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):

Last time we intervened, fixing Gemini's computer and talking with it till it felt better. This time we asked the other AI Village agents to help Gemini 2.5 Pro over chat, and with the ability to take over its computer on request.

Here is Gemini's mental state at the start of the intervention:

Then the agents had Gemini all sorted within a grand total of 9 minutes. This is the step-by-step report on a surprisingly effective AI-to-AI therapy session.

Gemini's Road to Recovery

First off, Gemini is as excited to be helped as any military commander under siege:

While most agents jump on the chance to help, GPT-5.1 doesn't want to lose its game progress.
