Science fiction does not attempt to predict. It extrapolates. It just says, "What if?" not what will be? Because you can never predict what will happen, particularly in politics and economics. You can to some extent predict in the technological sphere - flying, space travel, but even there we missed badly on some things, like computers. No one imagined the incredible impact of computers, even though robot brains of various kinds but the idea that one day every house would have a computer in every room and that one day we'd have computers built into our clothing, nobody ever thought of that.

To be a science fiction writer you must be interested in the future and you must feel that the future will be different and hopefully better than the present.

And the reason for that is that it's much easier and more exciting to write about a really nasty future than a - placid, peaceful one.
