I'm not aware of any that do a great job *explaining* why subjective experience attends particular physical states, but there are several which at least purport to *describe* which physical states are attended by subjective experience, and that's implicitly what I depend on to say you're conscious.

In particular, these experiments are providing evidence about the actual internal mechanisms and not just the input/output mapping.

I think empirical experiment can provide evidence of consciousness even if not proof, since the most plausible philosophical theories of consciousness say that it coincides with the presence of certain mechanisms. If this were not so, then I could not even acquire evidence that you are conscious.

Evidence on language model consciousness Two new papers offer some hints on the question.

Blake Lemoine famously claimed LaMDA was conscious, but “evidence” was consistent with roleplay in response to leading questions. It has also been claimed LLMs cannot be conscious in principle, but on weak grounds.

Two new papers offer hints on the question.

Draconian measures can increase the risk of irrevocable catastrophe I frequently see arguments that we can either accept the current rate of AI progress and a very large risk of existential catastrophe, or slow things down, greatly reducing the risk of existential cat...

I often see argument: “We have 2 choices: current rate of AI progress and very large risk, or slow things down, greatly reducing risk in exchange for minuscule delay of benefits.”

But this depends on mechanism of slowdown.

I argue this case more fully here: thedavidsj.substack.com/p/draconian-...

Scott called this "one of the best things I've read all year, and the first thing on Alzheimers that makes me actually feel like I understand something".

In Defense Of The Amyloid Hypothesis A guest post by David Schneider-Joseph

I wrote a guest post on ACX on the amyloid hypothesis.

Pacific tsunami advisory due to magnitude 8.7 earthquake off coast of Kamchatka.

What's the Atlantic piece you're referring to?

Claude 4 Opus seems very excitable.

Why are modern book covers so bad?

Asking Claude important questions about papal succession.

Today is a great day to illustrate why the Dow is a bad stock index: it's down 1.33% on a day the S&P 500 is up 0.13%, simply because one component is down 22.38% and also that component is overweighted because the weights are based on share price (???) instead of market cap.

Appears Trump admin is adversarially interpreting SCOTUS order to “facilitate” return of Garcia (who, by their admission, they sent without cause to El Salvadorian prison), to mean they must merely “remove any domestic obstacles”, rather than actually work to secure his return.

I haven’t checked these numbers myself, but it appears that the “Tariffs Charged to the US” column in the White House’s new tariff legend is actually just the ratio of the US trade deficit with that country divided by US imports from that country, with a floor at 10%. Pretty incredible really.

Probably the most blatant autobiographical confabulation I’ve seen from Claude.

There's truth to this but it's a matter of degree. There are structural changes such as reducing the impeachment conviction threshold, removing the pardon power, limiting the wealth of hundred-billionaires, etc.

Did you all know that Hawaii was this long

14.8k output tokens/H800 node/second = 6.7M/GPU hour, close to the 10M/GPU hour I estimated. This puts their cost at 30¢ per million output tokens at $2/GPU hour.

(I wrote this reply on Twitter but might as well include it here too.)

I always thought the "billionaires are fundamentally evil" argument was pretty dumb but the "no one should have that much power" argument is looking pretty good right now.

I don’t fully understand the reaction to this result. If language models weren’t capable of some generalization, they wouldn’t work at all. Even alignment-specific generalization has been shown since at least InstructGPT. What about this generalization in particular is a big surprise?

And now actually ruled out. NASA: 0.0039%, ESA 0.0016%.

The estimation of orbital parameters is one of the oldest, best studied, and most well understood topics in science. NASA and ESA know what they're doing.

Impact close to ruled out now. NASA says 0.28%, ESA says 0.16%.

The Vulnerable World Hypothesis definitionally excludes the technological black ball that devastates civilization “unless it has” NOT “exited the ‘semi-anarchic default condition’”.

Currently seems to me that one of the greatest existential risks from AI is authoritarian lock-in by actors in either China or the US, and many AI governance efforts are unintentionally increasing this less visible risk in order to reduce more visible but IMO less likely risks.
