> If I Google "What's the capitol of Illinois", I might get the Wikipedia page on Illinois
Ten years ago, maybe. If you did it during the last decade, your search was probably served by a natural language parser which would serve up the answer from a facts database before searching the web. Just checked, and for me it says "Illinois / Capital: Springfield" with big bold betters, and below that are suggestions for picture searches for Illinois, and even further below that is the web search results of which Wikipedia is indeed the first.
This used to be incredibly frustrating for me, as someone who actually uses Google for searching documents, not as a facts database. But I've had a couple of years to accept that a) others are not like me, and b) to check Tools / Results / Verbatim.
This ChatGPT-will-kill-Google talk seems like a lot of nonsense. Google has natural language search. Not only is it what that their Assistant does, they've long ago pushed it on everyone via Search. That won't die in the hands of a language generator. ChatGPT is both excellent and fun, but not a search killer.
