John Pardon won the 2026 Fields Medal. The Fields Medal is math's top global prize. It goes to a handful of mathematicians every four years.
Pardon studies symplectic geometry and knot theory. He gave a new answer about AI this month.
He spoke to the newsletter Future Class on Oct. 12. Pardon said he only started using AI a month earlier. He uses it mainly to check his own math proofs.
"The AI understands. 100%," he said. He explained how it catches small errors. He once wrote "all colimits" when he meant "all finite colimits." The AI caught the missing word right away.
A year ago, Pardon held a different view. Two or three years ago, his view was further still. Now he calls the shift world-changing for math.
A Reddit user named 141_1337 shared the quote Monday night. The post went on r/singularity. It gathered 22 comments fast.
Other Fields Medalists worry more than Pardon does. Some signed an open letter on AI and math this month. The letter warns that AI could erode real math understanding. Jacob Tsimerman, another Fields Medal winner, disagrees with Pardon's calm view. Tsimerman expects AI to write far more top-quality math papers soon.
Why did this story catch fire? A top mathematician rarely changes his mind in public. Pardon did, and he named the exact month it happened.
What does the reach say about the people building AI? Many mathematicians still doubt AI's grasp of hard proofs. A Fields Medalist now says the doubt missed something real. He frames AI as a careful reader, apart from any rival thinker. Wikipedia pageviews for John Pardon reached 143 on Oct. 19. The page for symplectic geometry drew 90 views the same day. Pardon still runs every proof by hand before he trusts it.
