I worry about a sort of idiocracy thing where we train the AIs on stackoverflow, stop using stack overflow and then find ourselves in a position where there's no stack overflow to train the AIs off haha.
This. StackOverflow was great in the early days, when answers were fresh. Now? It's like so much of the Internet: outdated. Add to that all the students posting their homework problems, and wrong answers by wannabes, well...
