From what I see of my own use and friends use of "AI" - it is a glorified search aggragator with nice pretty print output which has replaced Google search because all involved are tired of wasting time with the cesspool that vanilla search has become.

this is def. the #1 use case, and it's why we can't have nice things. I use the internet to go to places I already know most of the time; when I use a search engine to try and find something it's a complete failure - often because of all the LLM generated astroturfing.
