30 odd years ago this post would have been titled "Cleaning up after compiler generated assembly" ...

Hmm, ~30 years ago the compilers that I was using were generating generally fine assembly/machine code. Some of the other tooling was more troublesome: cross platform high performance numerically stable code and C++ static template deduplication paid for a lot of beers around then, and I needed them.

Compilers are deterministic and they actually possess domain knowledge of what they are trying to do. AI models are non-deterministic, have no real domain knowledge due to lack of an underlying world model, and their way of "writing" software is to spew out something that looks like something that they have been trained on, then iterate on it long enough until it has reached the level of being barely runnable.
