About a month ago was the final episode of ENTERPRISE. I just saw it last week. I assume that NONE of the readers are saying "Gee, how did he do that!"
At one time many computer scientists were also science fiction fans.
At one time both were small communities (with enrollment dropping computer scientists may return to being a small community).
At one time you couldn't time-shift how you watched TV so people would talk about the same show the next day.
At one time there was not so much Science Fiction out there so all the fans graviated towards the same materials.
So in the past there was much more cohesivness to the CS/Sci-Fi community.
There is no longer.
Is this good or bad?
I thing its good to NOT be so homogenous. New ideas come from all kinds of places. And you don't want people who are not Sci-Fi fans to NOT major in Comp Sci since they think they have to be.
