Vibe coding is great. You describe what you want, the agent writes it, the tests pass, you ship. It keeps working right up to the moment it does not: the job gets killed by the OOM reaper in production, or it opens ten thousand file descriptors and falls over, or it runs fine on the sample and melts on the real dataset.

100%, I’ve been writting: Rust, Haskell and Lean 4 with great success with AI. E.g. https://github.com/typednotes/hale

Yes the user has to be cooperative somehow. You could emulate linear/affine types like features with indexed monads though.

You are right, what I wrote is more of a PoC. It's valid for blocking sockets on the happy path.

Fair point! Updated. I’m definitely coming at this more from a Lean 4/formal methods perspective than a POSIX one.

Yes, I'm doing it without AI to learn the language, nonetheless I do think that Lean 4 + AI is a super-powerful combination.

Yes, this year I'm going for Lean 4: https://github.com/ngrislain/lean-adventofcode-2025

It's a great language. It's dependent-types / theorem-proving-oriented type-system combined with AI assistants makes it the language of the future IMO.
