Fields Medalists' Open Letter on AI Sparks Cross-Disciplinary Debate

Twenty-five Fields Medalists published an open letter, "A Severe Misalignment of AI in Mathematics," accusing AI companies of being severely misaligned with the goals of the mathematical community, after OpenAI claimed to have resolved the existence and smoothness of Navier-Stokes solutions, a Millennium Prize problem. The letter drew wide cross-disciplinary pushback and the debate continues.

Confirmed

• Computational biologist Lior Pachter explained on Sept 13 that he considered but ultimately declined to sign the letter, arguing the mathematical community itself is at fault and "not clean."
• Former Stability AI CEO Emad Mostaque published "Let a billion mathematicians bloom" on Sept 12, arguing AI will not destroy mathematics but instead bring millions of people into the field.
• Economist Joshua Gans responded on his Substack with "The Mathematicians are struggling."
• Stanford professor Anshul Kundaje amplified user nomad421's view calling the signatories' stance "21st-century Luddism," while noting the signatories themselves stated they are not opposed to developing or using AI in mathematics.
• Mathematician @meanfieldzane argued that mathematicians are falling into a trap set by the AI community—the scare tactic of "you will be replaced"—and that reflecting on how research paradigms will change reveals AI could enable more discoveries than ever.

Why it matters

• The dispute is not a binary pro/anti-AI clash: critics target how AI companies rushed to announce major mathematical results, while counter-voices argue the mathematical community's own institutional problems deserve scrutiny.
• Voices from industry (Mostaque) and economics (Gans) show the controversy has spread beyond mathematics into a cross-disciplinary public debate.
• Pachter's refusal to sign reveals real disagreement within mathematics itself over the letter's aims and framing.
• Some mathematicians advocate proactively rethinking research paradigms in the AI era rather than succumbing to displacement narratives.
