The thing is, a lot of questions user have aren’t unique, maybe just with a slightly different context and LLMs are good at adapting answers to other contexts.

But it only works for stuff that is already consolidated. For example, something like a new version of a language will certainly spark new questions that can only be discussed with other programmers.

I'm not sure this is true? Most languages have fairly open development processes, so discussions about the changes are likely indexed in the web search tools LLMs use, if not in the training data itself. And LLMs are very good at extrapolating.
