Predictions of the future are always,necessarily, extrapolations of the present. Back in the 1930's, when airplanes and cars were the hot techonology of the day, it was obvious to imagine a future with flying cars. Now, we're still going through the information revolution (at least in some countries) and it's easy to imagine a future with more pervasive computational technologies.
But I wonder what the next paradigm change will be. Some (Thomas Friedman among them) say it's going to be energy revolution: cheap, clean, available energy for everyone. I think that's a pretty good bet.
