I can't say for others, but this is what I do since Google integrated AI to the search results. For 80% of the time, I'd just type a question and read the AI summary and stop going further. For the other 20% or so when I believe deep diving is important, I'd scroll through results in the first page and click on a few of them to find out the "facts" myself.

The latter is what I used to do before AI summary was a thing, so I would logically assume that it should reduce the clicks to individual sites?
