Old man yells at cloud

Obligatory sample of AI takes
  1. The main current impact of LLMs on math is the privatisation of previously public research, whether that happens by virtue of mathematicians leaving universities and founding startups, or most universities having comparatively little access to computational power.
  2. The universities that do actually have access to such computational resources are, of course, disproportionally located in the richest areas. A future of AI-assisted mathematics where universities try to provide mathematicians with tokens just exacerbates already existing inequalities.
  3. I do not see the endless generation of theorems as the goal of mathematics, nor do I believe in a single correct foundational system or a hierarchy of importance of mathematical fields. I am highly suspicious of claims of "grand unifying theories" and "universal correctness". In that way, I think mathematicians are actually in a great position to reject LLM-based research solely based on the reason that it does not help the community. However, I do not yet know how one does this without losing all their funding.
  4. Formal mathematics has as much (or even more) to do with organisation, generalisation, simplification, and dissemination as with verification. Verification also works best when the process of working in a proof assistant helps you find your mistake yourself.
  5. On environmental aspects: the usual pro-LLM counterargument is that other industries are more wasteful, so, to be clear, I also don't think that {most domestic flights, most personal vehicles, golf courses, space travel} should exist either.
  6. I do not have major end-of-the-world anxieties. I do, however, believe that as with many other instances of not so great new technology being widely adopted, this is just further deterioration of workers' rights.
  7. I would be less extreme on my points if these companies were not ran by the worst people on the planet. I, however, also believe that having such an industry not be ran by the worst people on the planet is impossible, especially since the two best use cases for AI right now are weapons design and surveillance.

I also like the blog posts of Tasmin Chu, and the perspectives of the developers of the 1Lab and TypeTopology when it comes to formal mathematics.

Fonts

This website uses IBM Plex Mono: it probably has the most distinct italics among popular mono typefaces, and I wanted that. It also looks quite good. For my own computer stuff, I like Atkinson hyperlegible mono (very readable for small font sizes) and I would like to try Iosevka and Recursive. I have very strong and ill-formed opinions about LaTeX typesetting. Please ask me about them.

Music

I used to be genuinely interested in making music before I realised I'm much better at arguing about music theory for no reason.

Diary of assorted music opinions

Some music people I like, in alphabetical order.

Black Country, New road / black midi / Blur / Brian Eno / Cardiacs / Death / Gang of Four / Gentle Giant / Gorguts / Henry Cow / Kate Bush / King Crimson / King Gizzard and the Lizard Wizard / KNOWER / Pinback / Robert Wyatt / Sleepytime Gorilla Museum / Slint / Talking Heads / The Pop Group / Thinking Plague / This Heat / XTC

I list my favourite "classical" composers separately, because they were all probably horrible people.

Louis Andriessen / Alban Berg / Pierre Boulez / Luciano Berio / Alberto Ginastera / Sofia Gubaidulina / Paul Hindemith / Olivier Messiaen / György Ligeti / Edgard Varèse

some chords I think people should use.
