Previously, if you look at the trajectory of the industrial revolution, when machines replaced humans in one type of work, the solution usually came from low-skill work in new lines of business. So you didn't need any more agricultural workers, so people moved to working in low-skill industrial jobs, and when this was taken away by more and more machines, people moved to low-skill service jobs. Now, when people say there will be new jobs in the future, that humans can do better than AI, that humans can do better than robots, they usually think about high-skill jobs, like software engineers designing virtual worlds. Now, I don't see how an unemployed cashier from Wal-Mart reinvents herself or himself at 50 as a designer of virtual worlds, and certainly I don't see how the millions of unemployed Bangladeshi textile workers will be able to do that. I mean, if they are going to do it, we need to start teaching the Bangladeshis today how to be software designers, and we are not doing it. So what will they do in 20 years?
