Fields Medalist John Pardon: AI now truly understands my messiest proofs, 100%

2026 Fields Medalist John Pardon says AI now understands even his tersest, messily written proofs, catches subtle errors, and proves nontrivial results — "The AI understands. 100%." A year ago, he would have said the opposite.

In the quoted interview, he explains that AI proofreading used to be like spell-check, but now it grasps global context — catching that "all colimits" should have been "all finite colimits," which is only possible if it truly understands. Where he once reread proofs five times to be sure, he now has that certainty, and calls the progress world-changing for mathematics.
