2-billion-line Lean proofs: mathematicians debate proof without understanding
Singularitarian · x · 2026-09-09
Aram Pell asks what we actually learn from a 2-billion-line Lean proof of the Riemann Hypothesis, contrasting FLT's 13M-line formalization that still has a human-readable spine. Mathematician Alex Kontorovich pushes back: he'd iterate with AI on Lean proofs to compress and understand them, arguing formalization opens new paths to human understanding.
