SO was invented as a Q&A site, where human experts might answer specific technical questions, in a precise, preferably provable way. This is what machines now do well enough.

But there's a need to talk to human experts, learn their opinions, personal experience, non-obvious bits. E.g. I enjoyed asking certain questions at Software Engineering and Emacs SE sites. Sometimes I just ended up talking with a maintainer of a specific package I had questions about. This is something Claude and ChatGPT cannot easily replace, and maybe something that may keep certain SO communities alive. (Unless Reddit eats the remnants of their lunch.)
