What paid work might remain for human beings to do if we approach a world where AI is able to perform all economically useful tasks more productively than human beings? In this paper, I argue that the answer is not ‘none at all.’ In fact, there are good reasons to believe that tasks will still remain for people to do, due to three limits: ‘general equilibrium limits,’ involving tasks in which labor has the comparative advantage over machines (even if it does not have the absolute advantage); ‘preference limits,’ involving tasks where human beings might have a taste or preference for an un-automated process; and ‘moral limits,’ involving tasks with a normative character, where human beings believe they require a ‘human in the loop’ to exercise their moral judgment. In closing, I consider the limits to these limits as AI gradually, but relentlessly, becomes ever-more capable.
