In an op-ed column called Degrees and Dollars published in The New York Times Nobel Prize winning economist Paul Krugman of Princeton wrote concerning the impact of artificial intelligence and automation on jobs:
"The fact is that since 1990 or so the U.S. job market has been characterized not by a general rise in the demand for skill, but by “hollowing out”: both high-wage and low-wage employment have grown rapidly, but medium-wage jobs — the kinds of jobs we count on to support a strong middle class — have lagged behind. And the hole in the middle has been getting wider: many of the high-wage occupations that grew rapidly in the 1990s have seen much slower growth recently, even as growth in low-wage employment has accelerated."
"Some years ago, however, the economists David Autor, Frank Levy and Richard Murnane argued that this was the wrong way to think about it. Computers, they pointed out, excel at routine tasks, “cognitive and manual tasks that can be accomplished by following explicit rules.” Therefore, any routine task — a category that includes many white-collar, nonmanual jobs — is in the firing line. Conversely, jobs that can’t be carried out by following explicit rules — a category that includes many kinds of manual labor, from truck drivers to janitors — will tend to grow even in the face of technological progress.
"And here’s the thing: Most of the manual labor still being done in our economy seems to be of the kind that’s hard to automate. Notably, with production workers in manufacturing down to about 6 percent of U.S. employment, there aren’t many assembly-line jobs left to lose. Meanwhile, quite a lot of white-collar work currently carried out by well-educated, relatively well-paid workers may soon be computerized. Roombas are cute, but robot janitors are a long way off; computerized legal research and computer-aided medical diagnosis are already here.
"And then there’s globalization. Once, only manufacturing workers needed to worry about competition from overseas, but the combination of computers and telecommunications has made it possible to provide many services at long range. And research by my Princeton colleagues Alan Blinder and Alan Krueger suggests that high-wage jobs performed by highly educated workers are, if anything, more “offshorable” than jobs done by low-paid, less-educated workers. If they’re right, growing international trade in services will further hollow out the U.S. job market."
