And in fact has been since this day in 1992. I wont do an Issac Asimov tribute, I don’t feel that I could possibly do it any justice.
BUT, I would suggest the following video, its an interview form 1986 and its wonderful. Even if you don’t like Asimov, you should check out the video and note the hair on the female interviewer, its pretty awesome! :)
Update: Her name is Marilyn Mach Vos Savant, in 1986 she was rated the most intelligent person alive, apparently her IQ was something like infinity plus one (167-230).
