The great Golden Age of science fiction in the 1940s and 50s was perhaps the last time where there was a noticeable gap between science fiction and science fact. Since then, the pace of innovation has accelerated to the point today when we hardly have the time to think of a new invention before it is launched and discounted on Amazon.
In the 1950s, science fiction was used to explore mankind's reaction to the impact of technology, rather than the technology itself. John Wyndham was a master of this, exploring what happens when society breaks down due to genetic modification in the form of Triffids, by rising ocean levels brought on by the Kraken, or by our own prejudices in The Chyrsalids.
