Just read the first chapter of The Industries of the Future by Alec Ross. It describes how robots and automatization will probably steal human jobs. For example jobs like taxi driving (or even driving for Uber, think driverless Uber cabs), waitering in a restaurant, caring for the eldery and many more. Most of these jobs have a pretty high employment rate and are even under the top 10 of the most common jobs. What happens if all or most of those people lose their jobs? In the book Alec speaks about educating and reemerging them into a new job. But will there be enough jobs left? Of course with new industries new jobs are created. But won't those jobs require more specialized knowledge? And aren't more specialized jobs even rarer?
