Re: Sci-fi 'tech'
Actually there is at least one technological revolution in full flood right now: biotech (and GM). It's (surprisingly? ) far under most people's radar, because the main applications so far are
- pharmaceuticals, which we don't think about until we're ill, and then either the medics can cure us, or they can't and we accept our fate. No change since the middle ages, really, except the pills work somewhat more often these days.
- food, which we eat the same way whether it's GM or not, and most of us don't really know or care.
- raw materials (made by bacteria, GM or just selectively bred) which then go into the same old manufacturing chains. Once upon a time, citric acid was extracted from citrus fruit.
But one day soon, that might change dramatically. For example, on the optimistic side, what if instead of having a house built, you could just plant some seeds, and occasionally spray the developing house-treees with hormones to control the shapes of the walls and windows? Or grow GM seaweed that concentrates your element of need (Gold? Uranium? Europium?) out of the seawater, courtesy of a precisely engineered molecular sieve? Or solve global warming with a crop plant engineered to grow its roots far deeper than nature says it needs to, thereby burying lots of carbon for a long time?
And on the pessimistic side, it could all go horribly wrong (the cliche being zombie-horror fiction).
Some SF authors do get it, but a lot of those I've read illustrate that people who know their bioscience often don't know their physics.
