The late Arthur C. Clarke was credited with so many ideas, including the geosynchronous communication satellite and even the iPad, seen in David Bowman's hands in 2001: A Space Odyssey. By 1974 it was not a stretch to imagine the home computer, as people were already playing with them, but Clarke does a pretty amazing job of imagining its uses:
The interviewer complains that the computer will take over our lives, but Clarke demurs.
He will have, in his own house, not a computer as big as this, but at least, a console through which he can talk, through his local computer and get all the information he needs, for his everyday life, like his bank statements, his theater reservations, all the information you need in the course of living in our complex modern society, this will be in a compact form in his own house ... and he will take it as much for granted as we take the telephone.
It will enrich our society, because it will make it possible to live really, anywhere we like. A businessman or executive can live anywhere on earth and still do his business on a device like this, and this is a wonderful thing, it means we won't have to be stuck in cities, we can live out in the country or wherever we please, and still carry on complete interaction with other human beings.
Interestingly, this was even before Ken Olson, President of Digital Equipment, said "There is no reason anyone would want a computer in their home." Found on Neotorama.
