““People think--wrongly--that speculative fiction is about predicting the future, but it isn’t; or if it is, it tends to do a rotten job of it. Futures are huge things that come with many elements and a billion variables, and the human race has a habit of listening to predictions for what the future will bring and then doing something quite different. What speculative fiction is really good at is not the future, but the present--taking an aspect of it that troubles or is dangerous, and extending and extrapolating that aspect into something that allows the people of that time to see what they are doing from a different angle and from a different place. It's cautionary.””
