Robotics and artificial intelligence (AI) have fed two kinds of dreams, the first of the hopeful pleasant sort, and the other a nightmare. The first tells of great abundance, convenience and wealth. The other warns of job loss and widespread unemployment, among both workers and the managerial class. Both have some validity, but only up to a point. AI, like most technological advances before it, will offer society great advances in prosperity and productivity, though they will emerge at a slower pace than the enthusiasts predict. It will also take some jobs, but contrary to much commentary on the subject, it will not lead to mass unemployment.
