Not terribly surprising, Google would often direct me to StackOverflow threads as I was googling for an answer to a question. And as often as not, either the question was closed; or, instead of anyone providing an answer, the commenters would spiral off into questioning everything about the original question asker's life choices. While I do get the whole XY Problem, this sort of thing seemed to be over-used on SO.
Granted, I don't know if AI answers are any better. Sure, they can answer a lot of the simple questions, but I've not seen them be useful on hard, more obscure questions. Probably because those questions don't have ready answers on SO.
