I asked it how to derive some mutlivariate calculus equations, and it did it so well. An explanation so well refined, I was shocked. It explained it so well with each word chosen carefully with the best explanation that I have ever seen. No modern textbook, video, or professor I have had or seen did it this well. I was really blown away. It was like Lt. Cmdr. Data explaining it to me. What would take me hours to search and figure out from textbooks to see what the textbook is saying, it put it out simple and straight to the point within seconds. Fours hours of explaining something, down to 40 seconds. I don't think it is a fad, it is damn good at getting information. AI is like the jump from encyclopedia/libraries to search engines. It finds all the information for you and saves you hours of searching.
