well they always get the time scale wrong, and frequently the manor of exicution. what people miss is that fiction about science isn't about prediction, its just story telling, but its story telling that inspires and motivates, and because it does, sometimes in retrospect it appears to have been predictive, without having fully or usually even at all intending to be. the other thing often overlooked of course is economics and economic incentives. we've been, throughout history, cappable of many good things that we haven't done, not for lack of technical capacity, but because it turned out, that economics, and sometime just plain people, didn't want them. we have robotic workers, so to speak. not anthropomorpic ones, simply because there's no good reason for them to look like anything other then the industrial material handling systems that they are. likewise we haven't gone further in space or gotten there as fast as predicted because of cost vs interest and strength of incentives. nothing to do with lack of at lest potential capability. and there are a lot of political differences all over the place between what different people want and how bad they want or don't want it. and there's nothing to stop forgotten ideas from being re-examinied and re-approached from new and different angles. again its that time scale though that is always a very irratically and difficult to predict moving target.
the emergence of new technological capabilities and potentials, is always easier to predict then what people will and won't do with them. we make the part of the world we live in how it is, by how we live in it. sometimes this works out better then others.
Asimov was awesome for predicting what people would do with new technological capabilities and potentials.
