Cosa ci aspetta oltre la crisi? Come crescerà l'economia nei prossimi 50 anni ? Secondo Robert Gordon della Northwestern University economic growth is likely to slow sharply — indeed, that the age of growth that began in the 18th century may well be drawing to an end.
Mr. Gordon points out that long-term economic growth hasn’t been a steady process; it has been driven by several discrete “industrial revolutions,” each based on a particular set of technologies. The first industrial revolution, based largely on the steam engine, drove growth in the late-18th and early-19th centuries. The second, made possible, in large part, by the application of science to technologies such as electrification, internal combustion and chemical engineering, began circa 1870 and drove growth into the 1960s. The third, centered around information technology, defines our current era.
And, as Mr. Gordon correctly notes, the payoffs so far to the third industrial revolution, while real, have been far smaller than those to the second. Electrification, for example, was a much bigger deal than the Internet.
It’s an interesting thesis, and a useful counterweight to all the gee-whiz glorification of the latest tech. And while I don’t think he’s right, the way in which he’s probably wrong has implications equally destructive of conventional wisdom. For the case against Mr. Gordon’s techno-pessimism rests largely on the assertion that the big payoff to information technology, which is just getting started, will come from the rise of smart machines.
