Fields Medalists' Open Letter on AI Draws Backlash from Mathematicians and Economists
25 Fields Medalists co-signed an open letter, "A Severe Misalignment of AI in Mathematics," claiming a serious misalignment between the goals of AI companies and the mathematics community, following OpenAI's claim to have solved the existence and smoothness of solutions to the Navier-Stokes equations, a Millennium Prize Problem. The letter has drawn responses from multiple quarters and the controversy keeps escalating.
Confirmed
- Computational biologist Lior Pachter wrote on September 13 explaining why he considered but ultimately declined to sign the letter, with his core argument being that the mathematics community itself is also at fault—the community "isn't clean either."
- Former Stability AI CEO Emad Mostaque published a long essay, "Let a billion mathematicians bloom," pushing back against the medalists' concerns about AI harming mathematical research, arguing that AI won't destroy mathematics but will instead open the field to millions.
- Economist Joshua Gans published "The Mathematicians are struggling" on his Substack, responding to the open letter about AI's impact on mathematics.
- Stanford professor Anshul Kundaje shared and endorsed user nomad421's view that the signatories' stance amounts to "21st-century Luddism"; that view stresses the signatories are not opposed to developing and using AI in mathematics—they say so themselves.
Why it matters
- The debate isn't really a binary "pro- or anti-AI" standoff: critics object to how AI companies rush to announce major mathematical results, while rebuttals point out that the mathematics community's own institutional problems also deserve scrutiny.
- Voices from industry and economics like Mostaque and Gans show the controversy has spread beyond mathematics into a cross-disciplinary public issue.
- Pachter's refusal to sign shows that even within the mathematics community there is clear disagreement over the letter's demands and wording.
