I can't tell if you're trolling.
Nothing precludes you from doing that with AI-gen code vs human-gen code. What you just described is downstream.
If you have a human authoring code, you re-roll every time they release a new version. AI just releases versions faster, and in response to different, faster-moving inputs.
No I don't. I build predictable and deterministic pipelines. If I rebuild from a specific git sha, I expect the same output. If I get something different, I need to fix what's causing that.
