I don't mean writing a literature review. I mean reviewing the literature to find what I need. My point is that this was not practical with "fancy search" three years ago by which I mean Google-like search engines.

My example: I wanted to get a sense for the feasibility of doing a project that blends Gaussian Processes, active learning, and pairwise comparisons. So I want to dig into the literature to find out what is out there. This was around 5 minutes with Claude. In this case, I don't think I could have found what I wanted in 10 hours of searching and reading. This is the kind of thing that great LLMs unlock.
