The 500-Page Proof Nobody Can Read Is About to Be Checked by a Computer. The Result Won’t Matter.
Project Lana aims to formalize Mochizuki’s notoriously opaque 500-page proof of the ABC conjecture in Lean. But even if the computer says the formalization is consistent, the real debate—whether the formalization faithfully represents the original proof—will remain unresolved. The machine can’t end a controversy about meaning.
