Uncharted is quite subjective. I used SO most when I was starting out in SE. Looking back through the questions I posted, most of them were very much beginner questions that I would just know nowadays or know where to look for. That was what I used SO for. Beginners asking veterans for help. The least of them were due to bad documentation or exploring uncharted territory. As I grew more confident in the field, I stopped using SO more and more. The latest only for best practices on simple problems I don’t want to reinvent. And exactly those cases GPT now solves faster and I’d be surprised if not even better than SO posts.
