Thomas Hales on Lean prover reliability and AI

Mathematician Thomas Hales guest-posted on Terence Tao's blog about the reliability of proof assistants like Lean and AI-related concerns. He cites formalization projects including the four-color theorem, Feit-Thompson theorem, Kepler conjecture, and this year's sphere packing, Navier-Stokes blowup and Fermat's Last Theorem work as driving wider awareness of formal verification.
