Home Computer, Eh?
In my comments in the infamous sci-fi thread, I noted that the failures of most sci-fi are not purely "technological" but social, in that they can't get right the ways in which technology will be integrated into daily life. Well here's a good example of scientists not getting the future very right, precisely because they underestimated the power of their own disciplines and the speed of technological advance. It's also a good cautionary tale about extrapolating from the present to the future when we cannot even imagine the sorts of changes that will occur in the interim. Competition as a discovery process indeed.
