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.
SF's saga of the techno-sublime is about power, speed and transcendence of human limits. When science fiction gets over its trite romance with the parts catalog, it can achieve unnerving power. Late in life Huxley became a psychedelics guru, seduced by the potent allure of brain chemistry. Orwell holds the world record for scaring us away from a future that seemed perfectly plausible. Granted, political correctness and language theory haven't become Newspeak just yet.
