I doubt it. They've had problems with cheap automated answers for years where bots would essentially search for the question on SO and then copy an answer from another question verbatim. The answers were rarely useful because questions happen to be different even though they use the same keywords. Not only did they never bother to block that, they also didn't mind it and wanted to rely on the community down-voting those answers instead of at least blocking the bot -- and that's with a trivial check (identical answer already in DB). With something that's AI-generated, there's no chance. And with the general quality of many of the answers, there's no way to tell apart wrong answers from AI or humans.
