Agree, but only partially.

When I said "provide services previously not possible," it was just due to the fact that finding and allocating the talent to do analysis on Topic X, would have previously made many products too expensive and non-tech complex to provide.

Even if you just consider LLMs + harnesses to be an improved search tool, there is a lot you can make with a better search tool.
