I still would like to get other humans' experiences and perspectives when it comes to solving some problems, I hope SO doesn't go away entirely.

With LLMs, at least in my experience, they'll answer your question best they can, just as you asked it. But they won't go the extra step to make assumptions based on what they think you're trying to do and make recommendations. Humans do that, and sometimes it isn't constructive at all like "just use a different OS", but other times it could be "I don't know how to solve that, but I've had better lack with this other library/tool".
