2010: Odyssey Two was a novel by Arthur C. Clarke that was written in 1982. It was made into a movie called 2010: The Year We Make Contact two years later whose subplots differ from that of the novel.
http://en.wikipedia.org/wiki/2010:_Odyssey_TwoLet's discuss some of the technologies and technological milestones achieved between the time of the novel's first edition and now in the real world, and the fictional worlds of the book and film.
Technological hypotheses that didn't come to pass:
It was implied that at least one lunar base exisred in the late 90s. The film 2001: A Space Odyssey implies that there were at least an American one as well as a Soviet one.
The spaceships travelling to Jupiter are eqipped with nuclear fusion drives.
There is a manned spacecraft travelling to Jupiter with a crew of 10+ and rotating sections to generate artificial gravity.
People can be hybernated to be awakened when they arrive at their destination.
There are highly intelligent computers.
Technologies that now exist but weren't predicted:
Computer keyboards still look like they did in the early 80s in the film.
Flatscreens are only used for laptops. which are extremely bulky. All other television and computer displays, even on the Discovery One set are still CRTs. However, in 2001: A Space Odyssey back-projection screens were used, also on the sets of the Discovery One possibly to mimic flat screens!
