But I do really grasp it, although that might be hard to prove on an internet forum.Saying it and really grasping it are two different things. Maybe, if so many people are asking this question (and I seem to recall several people making the same observation recently) it's something you should think about.
But that doesn't mean stuff in fiction can't become real. Flying machines and pocket super computers at one time were pure fiction, now they're both real and in common use.
