What I mean by "deep" is that I can ask a simple question and it gives thorough and relevant answer. Then I pick a point to drill down on and it's happy to expound, ad nauseam. That's deep. I totally realize that it's not going to be coming up with anything that hasn't already been written about, but that's more than good enough to satisfy my needs and it's a hell of a lot more knowledgeable than any person. Can it be wrong? Of course, but usually not as wrong as a human would be.
