Yep, definitely wrong train. Now I remember. Hey, but I didn't cheat...LOL Yep, you are dead on about "I, Robot". A few movies have touched on it recently, too. In a similar but different sort of way. "AI" and the Robin Williams movie (I forget title). Heinlein's "Stranger" is a good read. The follow-ons got a bit deeper into religion that I liked. The same thing happened with the "Dune" trilogy. But, I guess, it is to be expected. But, you summarize authors so darn well !
