I think what people mean by everyone varies a lot, which is why I wanted to draw attention to more specific numbers. For example, in the Datos data cited[1], on desktop 86% were using traditional search engines >10 visits/month vs. only 21% for AI chat tools. That is indeed a very significant percentage, but more than 4x less than search and (at least I) wouldn't say that ~1/5 is "everyone."

Kinda like how quickly cellphones popped up and changed everything.

yeah exactly my thoughts. everyone didn't mean literally everyone.

and for the ones that are using it (especially the paid subs). the lure is undeniable.
