Happy to announce our latest paper! We argue that a solipsistic superintelligence is unlikely to be cooperative. "Solipsism" in the development process can give rise to self undermining in deployment. So, is humanity now building solipsistic or non-solipsistic AI? arxiv.org/abs/2606.03237

great paper to point to now when referencing this top-down influence. I think finding out how to tease its effects apart from those of the bottom-up agent planning influence will lead to real advances in understanding and modelling social systems.

Another possible evolutionary path is one where an ecosystem of agents is designed so well that the interactions between them have the same sort of entertainment value for spectators as reality TV or fiction does. (Spectators might also be participants at times: the Westworld model.)

Yes, in part. I think the parasocial relationship to fiction writers is stronger than to (say) illustrators or stock photographers (though not fine art). But more centrally I mean that a lot of writing — including utilitarian stuff like reports — matters because it expresses someone’s stance. +

This chart (which applies even more to social media than it did to TV) lives in my head rent free. Social media enveloping traditional media means everything and everyone is now competing in the entertainment market. Boring stuff like policy that affects millions of lives doesn’t stand a chance.

Interesting mystery. It is known that animals can learn to control neurons pretty much anywhere in the brain. But they can not learn to ignore hunger which probably means they can't turn of hunger sensing neurons. How is that avoided in the brain? They even have DA inputs.

Is our self-conception as homo faber / "tool-using animals" just because stone endures better than behavior? If we had ethnographic records of australopithecines, H. erectus, &c, would all the stages between simian communication and "language" add up to a story more fascinating than flint?

Like, even before JS Mill gave us a utilitarian ("net upside") argument to justify freedom of speech, there was an older intuition that banning symbols risks doing violence to thought itself, and ought to be approached with "warinesse."

My favorite part of pragmatism is when it’s like “maybe instead of worrying about shit that doesn’t matter we should worry about shit that does.” “Oh and btw we’ll learn a lot more about the shit that doesn’t in the process anyway.” 🫣

This paper is a great exposition of how "personhood" doesn't need to be, and in fact should not be, all-or-nothing or grounded in abstruse, ill-defined metaphysical properties. As I argued in my recent @theguardian.com essay, we can and should prepare now: www.theguardian.com/commentisfre...

This sounds cynical—but represents a huge advance over empty “AGI” speculation. It’s a political question, not a technical one. Without social equality models *cannot do* many kinds of work (eg, negotiate agreements or manage workers). So they will only be human-equivalent if we decide they are.

One can also explain human behavior this way, of course 😉, we are all role playing. But I certainly agree with the advice you offer in this thread. Humans harm themselves when they stop playing roles that connect to other humans.

Love the insight that language models have been more widely useful than video models. For Levine, this is because LLMs kind of sneakily and indirectly model the brain. I would be tempted to say instead that shared languages are more powerful than single brains. But either way, it’s a good read!
