Yeah, people get upset when you spew out total bullshit.

I work as a performance specialist and "AI writes code like that" is utter nonsense. AI writes the same terrible performing code that was the mediocre developer standard on Stackexchange and other codebases it ate.

You still need a lot of vigilance and time to make well performing software and most software engineers just don't give a damn if we don't outright block their PRs/feature launches before passing performance tests.
