AI Safety Fact vs. Fiction | YC Paper Club

This episode of Paper Club addresses AI safety from a scientific perspective, contrasting it with recent media sensationalism. Stanford professors Clark Barrett and Mykel Kochenderfer discuss how automated reasoning can mathematically prove code security, how aircraft stress-testing methods are being adapted for language models, and the potential need for an NTSB-like agency for AI, highlighting the real-world engineering challenges and solutions for AI safety.

Your Code Has Bugs. Lean4 Has Proofs: Formal Verification for Engineers — Varun Pant, AWS

Varun Pant introduces formal verification as the solution to reliably validate AI-generated code, proposing a division where humans define specifications and machines handle code and proof. He details Lean's role as a unified language for code and proof, exemplified by an AI rewriting zlib with 32,000 lines of proof, and AWS's Cedar using Lean specs with Rust production code reconciled by 100 million nightly tests. The talk also covers deductive verification with solvers and future cross-language verification with Strata, aiming for "provably correct" software.
