And the predictions about computers were pretty indequate. E.M. Forester had it in "The Machine Stops" (1909) that people would use computers for chatter--but the field completely forgot that insight.
No one guessed what would be easy and what would be difficult--grand master chess has turned out to be a more solvable problem than vision and walking. Once upon a time, science fiction writers seemed to think that your first problem with a computer was keeping it from trying to take over the world rather than getting it to to work at all.
And no one had the foggiest that there would be whole sections of books for the general public on dealing with computers, nor that computers would make it reasonably easy for people to have a combined printing press and post office at home and this would be problematic.
Afaik, no one in science fiction has taken a real crack at just how complicated nanotech is going to be.
