From Paul Krugman's NY Times book review of The Rise and Fall of American Growth: The U.S. Standard of Living Since the Civil War by Robert Gordon:
"First, he points out that genuinely major innovations normally bring about big changes in business practices, in what workplaces look like and how they function. And there were some changes along those lines between the mid-1990s and the mid-2000s — but not much since, which is evidence for Gordon’s claim that the main impact of the I.T. revolution has already happened.
Second, one of the major arguments of techno-optimists is that official measures of economic growth understate the real extent of progress, because they don’t fully account for the benefits of truly new goods. Gordon concedes this point, but notes that it was always thus — and that the understatement of progress was probably bigger during the great prewar transformation than it is today.
So what does this say about the future? Gordon suggests that the future is all too likely to be marked by stagnant living standards for most Americans, because the effects of slowing technological progress will be reinforced by a set of “headwinds”: rising inequality, a plateau in education levels, an aging population and more.
It’s a shocking prediction for a society whose self-image, arguably its very identity, is bound up with the expectation of constant progress. And you have to wonder about the social and political consequences of another generation of stagnation or decline in working-class incomes.
Of course, Gordon could be wrong: Maybe we’re on the cusp of truly transformative change, say from artificial intelligence or radical progress in biology (which would bring their own risks). But he makes a powerful case. Perhaps the future isn’t what it used to be."
