Oh, I know we won't have our flying cars by then. Remember the one story that Issac Asimov wrote? I think the name was 'life in the year 2000' - or something like that. He predicted that not only would we have flying cars, but we'd have colonies on the moon, as well as mars. Not only that, but all major diseases will be cured, and the threat of pollution was to be non existent and robots would carry out all of our household chores. By the way, the book was written in the sixties and he was off by quite a long shot. That's what we get when we expect one of the greatest science fiction writers to make realistic predictions of the future. Bah.
There's nothing on the moon or mars - so why can't we just focus our efforts on some damn flying cars!
