I was watching 2001: A Space Odyssey again the other day. Clarke and Kubrick got a lot of it right. They made that stuff up in 65-68. What impressed me, as it always does, was how much cooler the real stuff is when it finally gets here, than it is imagined it will be in science fiction.
I remember being really amazed by the Discovery crew's rubber map style news pads when I saw the movie back in '68. I read in Popular Science back then that those news pads were really going to be around in the future. A flat, portable, TV screen that has news and TV shows transmitted directly to it! Clarke and Kubrick were off by about 10 years on that one (iPad).
And the name of their ship, Discovery; another Discovery just finished its final voyage today.
