Those of us who love science fiction are used to this. It's fun to go back and read what some of the authors in the 1950's thought the future would look like. My personal favorite is that no thought it given to miniaturization; everything still uses tubes. Exotic tubes with magical abilities (like the power tubes in the Venus Equilateral series), but still vacuum tubes with filaments.
When it comes to computers, it's just as hit and miss. The way some authors handle artificial intelligence is by insisting that it won't happen. (David Weber, to name one -- in his books, the idea is that any true AI would quickly go insane.)
(But then, poor David has other concerns: in the Honor Harrington series, one key to Manticore's military superiority is the fact that they've harnessed "gravity waves" for faster-than-light communications
Likewise when I see anyone in a story "pressing a button" (even if it's a virtual button). We're already on the brink of direct neural interfaces. You think it, things happen. That's the future. But to be fair to these authors, it's hard to see what's coming in 10 years.
