This hasn't been my experience. Yes, chatgpt gets stuff wrong, and fairly regularly. But I can ask it my question directly, and can include sample code, and I get an answer immediately. Anyone going on stack overflow has to either google around and sift through answers for relevance, or has to post the question and wait for someone to respond.

With either chatgpt or stack you have to check the answer to make sure it works - that's how coding goes. But one I know if it works or not pretty much immediately with fairly low investment of time and effort. And if it doesn't, I just rephrase the question, or literally say "that doesn't seem to work, now I'm getting this error: $error"
