I think a lot depends on where "on the curve" you are working, too. If you're out past the bleeding edge doing new stuff, ChatGPT is (obviously) going to be pretty useless. But, if you just want a particular method or tool that has been done (and published) many times before, yeah, it can help you find that pretty quickly.
I remember doing my Masters' thesis in 1989, it took me months of research and journals delivered via inter-library loan before I found mention of other projects doing essentially what I was doing. With today's research landscape that multi-month delay should be compressed to a couple of hours, frequently less.
If you haven't read Melancholy Elephants, it's a great reference point for what we're getting into with modern access to everything:
I'm about 50/50 between helpful results and "nope, that's not it, either" out of the various AI tools I have used.
I think it very much depends on what you're trying to do with it. As a student, or fresh-grad employee in a typical field, it's probably much more helpful because you are working well trod ground.
As a PhD or other leading edge researcher, possibly in a field without a lot of publications, you're screwed as far as the really inventive stuff goes, but... if you've read "Surely you're joking, Mr. Feynman!" there's a bit in there where the Manhattan project researchers (definitely breaking new ground at the time) needed basic stuff, like gears, for what they were doing. The gear catalogs of the day told them a lot about what they needed to know - per the text: if you're making something that needs gears, pick your gears from the catalog but just avoid the largest and smallest of each family/table - they are there because the next size up or down is getting into some kind of problems engineering wise, so just stay away from the edges and you should have much more reliable results. That's an engineer's shortcut for how to use thousands, maybe millions, of man-years of prior gear research, development and engineering and get the desired results just by referencing a catalog.
