American society prefers having supergizmos dropped on its head out of nowhere, with no time to prepare and no real thought of the consequences. We love it that way. It's livelier, funnier, freer and just more American. If science fiction outlived the OTA, it also gets more girls, gold and glory than its other big rival, professional corporate futurology. Corporate trend spotting, after all, is limited to gizmos that might conceivably make someone money.
Science fiction is a fun-house mirror for a society warped by raging technological advance.
Science fiction doesn't want or need to make much sense. It seeks astonishment, terror, wonder, ecstasy and dread. It is spectacular and mythic, an oxygen tent for society's daydreams. Science fiction cordially ignores many vital technologies, such as, say, garbage recycling. Recycling is hugely important, but it has zero science-fictional thrill.
