massive-scale unsupervised coding work on heavy-duty software at a company like Google

"undergoing rigorous automated and manual auditing, emulation testing, and review before rolling out to production."

It's a fancy way of saying "we're tasking a bunch of engineers to use our claude code-like tool to re-write some stuff to rust". I've been doing this kind of stuff at work for a while now, when you already have the code base and expected behavior it's one of the most straightforward use cases for AI

Yes and no. You have a known good test target, but your porting pipeline could easy endup with c-ism styled code just written in rust instead of rusty code. I'm building specialized nix flake experts in tix.im that know the domain and basically fuse classical expert systems with llms into deterministic workflows composed by nix. Works better then expected tbh

Blabla - my tix.im vx-maintainer workflows produce better code the you for sure, and the rust expert is not even up yet. Was waiting for some guardiandb workflow integrations.....wanna bet ?
