cryptography and pretty proofs | PL-curious | everything is MPC | assistant professor @ VU Amsterdam

- Paper 488 claims to prove P = NP. Paper 872 claims to prove P != NP. At least one is wrong! (My wager: both) - 339 submissions have only one author, 286 different authors have at least one solo-author paper. About half these authors have never published in STOC/FOCS/SODA before

We should also keep track of the number of AI-generated results desk-rejected from conferences and journals due to being of subpar quality, to help keep things in perspective. "OpenAI announces 722 desk-rejections from leading scientific venues!" would not have the same ring, I know.

"The apparent complete lack of care to do undergraduate-level code clean-up is striking, even if the code compiles ok. One can then perhaps extrapolate to the quality of the English writing that the system has put out."

I felt like I had come to a place to actually say something worth saying about last week's dump of AI-generated claimed results. https://thehighergeometer.wordpress.com/2026/10/12/what-even-is-mathematical-output/

“Now Lean, particularly in Navier-Stokes papers, is being used as a time-stamp, a way to claim your theorem before having to write it up properly in an explainable way.” A sentence that would’ve been seen as the ravings of a madman just ~1 year ago. blog.computationalcomplexity.org/2026/09/navi...

Fantastic thread on math’s over-indexing on problem solving but applies to theoretical CS and crypto as well (in fact I think TCS and crypto are worse than math in this regard). Took me a few years after my PhD to converge to this viewpoint as well but I always thought I was just odd

Let me expand upon this 🔽 and say something about AIs, mathematics, proofs, conjectures, problem-solving, goalposts, paperclips, genii and, more importantly, Campbell/Goodhart's law. 🧵⤵️ •1/38

I kinda consider this a soft confession to what I was theorising 1) He admits they only care about maths in so far as it brings good PR 2) they're only interested in announcing results that make it sound like they're gonna replace mathematicians ∴) they're optimising for impressive-soundingness

Today I was asked why we haven’t announced more math results from Astra since these problems.

At 
@OpenAI
 we aim to devote time to finding and announcing math results from internal models only when they would meaningfully change people’s understanding of the pace of AI progress. Our main focus is shipping great models so everyone can use them to make discoveries of their own.

The post is a quote retweet of a post from August 1st sharing 10 major open problems in mathematics, saying

An internal version of Astra, @OpenAI’s next major model family, solved 10 major open problems in mathematics, quantum complexity, and theoretical computer science.

We believe it will be a major step for scientific reasoning....

I think if I were an AI company trying to create a perception that AIs were going to replace mathematicians, what I would do is grab a large set of high-profile open problems and just start grinding counterexamples until I've found one, and then only report what went into finding that specific one

Anyway, your problem isn‘t finding the time to take notes. The problem is that taking notes is thinking and thinking has to be done by someone. women have been doing a lot of metacognition that looks like a task when it’s really thinking.
