Cheap code means formal verification is reasonable now — Antfly Blog

kept by eddie may 22

The Antfly team shows how coding agents using TLA+ can formally model distributed systems to cheaply find and verify race conditions and other bugs.

Coding Agents Meet Distributed Reality
AI-generated distributed code should target frameworks like Hydro that make common concurrency bugs compile-time errors rather than runtime failures.

Don't Vibe — Prove
Dependent types in Lean 4 unify specification and implementation, letting AI generate provably correct code while the compiler verifies correctness automatically.

On the success of 'natural language programming' - Marc's Blog
Natural language programming succeeds because software has always been built through conversational specification loops, and LLMs now include computers in those loops.
