As a matter of fact, I can't even remember the last time it happened when programming.
AI can only generate the world's most average quality code. That's what it does. It repeats what it has seen enough times.
Anyone who is really never correcting the AI is producing below average code. (Edit: Or expertly guiding it, as you pointed out elsewhere in the thread.)
I mean, I get paid either way. But mixing all of the worlds code into a thoughtless AI slurry isn't actually making any progress. In the long term, a code base with enough uncorrected AI input will become unmaintainable.
