Lots of new followers. Maybe it's time to do a quick intro post (can't remember if I did one in the past).
I work on AI for games, games for AI, open-ended learning, and AI applications in various fields. I also often have opinions on various things, many but not all of them related to AI.

It is unavoidable that AI will be a major political issue soon. Or perhaps more appropriately: several major issues. I write more about this here:

I recently read "Mathematica" by David Bessis, and I think it's a fantastic book! Before I recommend it to everyone, I would love to hear from people who do mathematics, or at least prove a theorem now and then. Do you agree with Bessis' description of what mathematics is and what mathematicians do?

How does one ethically ensure that one’s Wikipedia page is updated? Mine is out of date and incomplete. I understand that I’m not supposed to edit it myself. I’m happy to pay to have it updated, but is that also against the rules?

I have decided to cover my desk in my office with Legos because why not? Why don’t you do it yourself? You know you want to. It’s awesome. Now, me and my students and collaborators build things together while we have our meetings.

If you're instead interested in my opinions (but why?) you can entertain yourselves by reading my blog. I rarely write things there, but when I do, it's basically rough drafts of uneven quality.

It’s probably just a shortcoming of the harness, but it *could* be some self-deprecating humor from Grok. Anyway, it’s funny.

1. In Hamburg there is a "fully autonomous train" that for some reason has a human operator to press the ON switch first thing in the morning and the OFF switch at the end of the night. In a recent talk about AI in science, I asked the audience to consider whether they want to be like that operator.

I'm not sure people really get what full replacement of human understanding & decisions encompasses. Even past the spectre of job loss, that's a direction towardsglobal reduction in human capacity for critical thinking, creativity and decision-making at intensities greater than "hobby for fun."

Modern LLMs are good at writing code, but not necessarily at optimizing policy. But you can wrap the LLM in an evolutionary framework, and search for policies. In a new Nof1 paper, we show that we can automatically generate strong trading policies.
