When I have a good idea that I can hit what I want in a single query, I still use search engines directly a lot. But I have found AI is pretty decent at automating the process of making a vague search, picking up from the search better search terms, then making a couple of other wrong searches, then refining down to what I really want and potentially pulling together an answer from multiple sources. I know how to do all that, but the AI can do in a minute what may take me 15 minutes.

I'd say I also know I can still do it, but... as the search engines deteriorate it is getting somewhat harder to do this by hand than it used to be. I still do this by hand sometimes for cases where I want the exploration of a topic for myself, rather than a focused answer where I don't really care about what I learn along the way, and it's getting harder. I don't know that it'll converge at "zero value" but the search result pages seem like they're just... harder to use for this than they used to be, though it's hard to put my finger on how.
