I've thought about this on and off, and one day I arrived at this: The only technological progress that truly matters to me are medical ones.
If people could live and not get sick, and not die until they're 90, then I would be fine living with 1970's era tech, or whatever year's era tech. Then all we'd need would be to have less violent, more egalitarian societies, à la Scandinavia.
Flying cars, faster+cheaper computers, better internet be dammned. (or they could go on being improved, but I wouldn't care if not)<p>P.S. I never get the flying car thing, since we have helicopters.
