What are some ideas/innovations you first encountered in a sci-fi movie or book that, lo and behold, actually came to be afterward? what are some innovations they missed that seem more probable than those they hit?

Many years after watching it for the first time, I viewed 2001 a space odyssey and I noticed a couple of interesting things.

First, the movie predicts velcro. It also predicts visual teleconferencing. However, in the scene just before lift off to the moon, the main character jumps into a telephone booth to make a call – the idea of a cell phone was too far fetched at the time, but when you think about it…

Of course, the movie had more misses than hits as human interplanetary travel seems more unlikely today than when the classic was produced.

What are some examples of sci-fi ideas/innovations, hits and misses, that you can come up with? What are some as yet unrealized ideas/innovations that you expect will be realized in your lifetime?
