Fei-Fei Li's World Labs raised $1B from A16Z, Nvidia to advance its world models
Summary
This post explores learning the Lean theorem prover to formalize mathematics, arguing that formalization helps separate human intuition from mechanical proofs and can aid AI systems in understanding mathematical thought. It describes a three-layer object model in Lean, discusses dependent types, type classes, and historic foundations, and envisions a two-tier collaboration between humans and AI for future mathematical writing and proof development.
