In my computer science undergrad program, we watched and discussed a movie about Joseph Weizenbaum and Ray Kurzweil. I still vividly remember that discussion.

At the time, it seemed obvious to me that Kurzweil got it right and Weizenbaum got it wrong; that clearly, ELIZA was a red herring; that people wouldn't be fooled that easily; that the first AI to truly pass the Turing test would be the real thing (and we'd definitely see one, and with that the Singularity, in my lifetime).

I think about Weizenbaum a lot these days.
