Tao on AI math repo at ~42% formalized: AI less helpful for fuzzy math tasks than hoped

danintheory's team updated their GitHub math repo with 6 new Lean formalizations, 19 modifications, and 3 withdrawals; roughly 42% of top-line results are now formalized, with ongoing updates and errata.

Terence Tao commented that one withdrawn manuscript, Algebraicity of Kuga–Satake Correspondences for K3 Surfaces, was a question he likes with seemingly exciting ideas. He notes that wrong human-authored arguments often still contain salvageable intuitions, but it's unclear whether that's possible here — and his experience is that AI is less helpful for this kind of fuzzy task than one might hope.
