What model(s) are you using?
I don’t know if it’s important but it seems like it’s important to stress that it’s not a search engine at all. Maybe there are times when they are useful as a search engine, but mostly it’s a thinking engine.
And when i use it as a search engine, I think of it as almost the opposite of robust - I think it behaves more like one person‘s opinion, rather than a summary of what humanity is saying about a topic.
Totally agree that the future is speculation, but also projecting that past trends in capability improvements will continue (especially as it gets exponentially more funding and attention) doesn’t seem too crazy.
One thing search engines can’t do is think with you about something that’s never been asked before. These can.
