The people who are using AI to improve what they were already doing anyway, aren't going around expounding "I made this with AI!"
Like one of my personal projects is a sort of "middleware" for Godot, and it needs to be lean, precise and match certain rules, because it's meant to be used by many games, so I can't blindly trust AI to generate code for it, it'd be too sloppy,
BUT Codex reviews have been a great help in finding bugs that would have taken me ages to even notice on my own. Some of those AI findings helped me overhaul entire subsystems, still manually coded.
