Entropy from first principles

I really appreciate this comment!

And yeah, that's why I said only "Note that...", and not something like "don't trust this guy". I think the content of the article is probably true, and maybe it's Metz who wrote it just because AI is his beat. But I do also hold tiny models that say "maybe he dislikes us" and also something about the "questionable understanding" etc that habryka mentions below. AFAICT I'm not internally seething or anything, I just have a yellow-flag attached to this name.

Note that the NYT article is by Cade Metz.

I think the biggest thing I like about it is that it exists! Someone tried to make a fully formalized agent model, and it worked. As mentioned above it's got some big problems, but it helps enormously to have some ground to stand on to try to build on further.

I love this idea!

Some other books this could work for:

  • The Ancestor's Tale
  • The Art of Game Design
  • The Anthropocene Reviewed
  • The LessWrong review books 😉

Many textbooks have a few initial "core" chapters, and then otherwise a bunch of independent chapters on applications or assorted advanced topics.

You can "bookmark" a post, is that equivalent to your desired "read later"?

Welcome kjsisco! One good place to start interacting with others here is on the current open thread.

Hm... so anything that measures degree of agent structure should register a policy with a sub-agent as having some agent structure. But yeah, I haven't thought much about the scenarios where there are multiple agents inside the policy. The agent structure problem is trying to use performance to find a minimum measure of agent structure. So if there was an agent hiding in there that didn't impact the performance during the measured time interval, then it wouldn't be detected (although it would detect it "in the limit").

That said, we're not actually talking about how to measure degree of agent structure yet. It seems plausible to me that whatever method one uses to do that could be adapted to find multiple agents.

This will make more sense if you have a basic grasp on quantum mechanics, but if you're willing to accept "energy comes in discrete units" as a premise then you should be mostly fine.

My current understanding is that QM is not-at-all needed to make sense of stat mech. Instead, the thing where energy is equally likely to be in any of the degrees of freedom just comes from using a measure over your phase space such that the dynamical law of your system preservers that measure!

Maybe it could be FLCI to avoid collision with the existing FLI.
