Maybe. But, it's been over a year since I used StackOverflow, primarily because of LLMs. Sure, I could use an LLM to formulate a question that passes SO's muster. But why bother, when the LLM can almost certainly answer the question as well; SO will be slower; and there's a decent chance that my question will be marked as a duplicate (because it pattern matches to a similar but distinct question).

>hen the LLM can almost certainly answer the question as well;

You say this in a thread specifically talking about how LLM's fall apart when digging deeper into the surface of questions.

Do people really want to learn and understand, or just feel like they are learning and understanding?

I would say that LLM might give a correct answer, in a good enough question there is more than one answer.

Furthermore the LLM might give an answer but probably not explain with the best skills available why the answer is the way it is. This is of course something that varies with StackOverflow but there it is at least possible that somebody with deep technical knowledge decides a question is worth answering deeply.
