The low-hanging fruit of technological progress

The website Alternative Right has an interesting article on the declining pace of technological progress:

The world of 1959 is pretty much the same world we live in today technologically speaking. This is a vaguely horrifying fact which is little appreciated…Certainly, people can be forgiven for thinking we live in a time of great progress, since semiconductor lithography has improved over the years, giving us faster and more portable computers. But can we really do anything with computers now that we couldn’t have done 30 or even 50 years ago?…Some wise acre is likely to pipe up and sing the glories of “Nanotech,” a “subject” which was “invented” in K. Eric Drexler‘s Ph.D. thesis in 1989. In the 20 years since he penned his fanciful little story, we have yet to see a single example of the wondrous miniature perpetual motion machines Drexler has been promising us “real soon now.” I wonder what his timeline for delivery of this “technology” will be?

The author dismisses the idea that the rapid technological progress between 1959 and 1909 was possible because these generations focused on the “easy stuff” but I wonder if this explanation can be so easily dismissed. Even if we allow for the credible hypothesis that laissez-faire capitalism is more conducive to accelerating technological change than a mixed economy, it cannot be ignored that commercial incentives favor picking the low-hanging fruit first. The current generation is left with more complicated technological  and biomedical objectives such as molecular nanotechnology and rejuvenation of the human body.

A sober mind should never get too carried away with either optimism or pessimism. One major advantage of making cryonics arrangements is that it eliminates some of the anxiety that comes from recognizing that credible rejuvenation therapies may not become available in your lifetime. Patients in cryostasis have time, a point that is not always fully recognized by skeptics of accelerating technological progress.
