When I was young there was all sorts of crazy ideas in science fiction. Take, for example, Star Trek. They had tiny flip-open communicators and tricorders that could tell what's happening inside someone by just pointing it at them. Everybody knew those things were impossible but as the years went by we were proven wrong. Those writer's imaginations became real with cell phones, computers, space telescopes and all sorts of other inventions. Eventually science fiction became science fact.
I guess we didn't learn. When "Terminator" came out we thought it was full of impossible ideas too.
