I did a code review for a really, let's just say "challenging", co-worker a few years ago. There was one block of code that was really obtuse and I couldn't figure out why it was there and what it did. So I asked him.

He sighed like he was taking responsibility for a grave sin and I should admire him for it, and said, "I don't know. I copied that from StackOverflow."

I've felt that AI is just an amplification of what we've all done and been through with SO answers.
