UC Berkeley mathematics professor and Fields medalist Richard Borcherds says he now grades homework for completion rather than correctness as students increasingly obtain answers with AI. He acknowledges that the approach is unsatisfactory but says he lacks a better alternative. The university leaves course-level AI policies to faculty and asks them to state expectations in syllabi; tested AI-detection tools have not been adopted as a campus standard. One professor’s change should not be mistaken for an institution-wide end to homework or evidence that mathematics education is pointless.
