But more importantly banning AI generated content from Stack Overflow doesn’t solve the “problem” you’re describing.
Its an absurd equivalence. A human can never "dominate" no matter how much they learn.
Training for free a closed, for-profit private enterprize infrastructure that will eventually make your preferred free collaboration platform obsolete is like the ultimate of naivete (or vested interest).
Somewhere an autocratic leader is laughing at you.
Put more succinctly I'm making two points: 1) The free work is already being done. 2) StackOverflow has been crawl-able since forever.
You'd have to address both of those problems before the concern that you're raising becomes relevant. Banning the posting of new generated content doesn't address either of those things.
The baseline you mention is already an issue that is being debated hotly.
My comment was that humans reviewing and fixing new AI content is exactly not what should be done in the current circumstances.
