You've probably heard about that 2013 study by two University of Oxford researchers that found 47 percent of U.S. jobs, most of them in the service sector, to be at high risk of "computerisation" over the next decade or two. Other researchers have since argued that this overstates the risk because, while certain tasks are likely to be automated, most jobs involve multiple tasks. A study out last month from the Organization for Economic Cooperation and Development, for example, found that just 14 percent of the jobs in 32 affluent OECD-member countries studied were "highly automatable," although another 32 percent were likely to see "significant change in the way these jobs are carried out as a result of automation." For the U.S., which is already further along in automation than OECD members such as Slovakia and Greece, those percentages were 10 and 28. So that's a little bit reassuring, but it still fits along the depressing spectrum of Are the robots going to take all of our jobs,...
