I have seen entire warehouses run by one person and a bunch of robot forklifts, restaurants that only have computer ordering, stores with only self checkout, customer service lines that are only computers, websites that only have chat with a computer. AI is eventually going to make it almost impossible to tell if your talking to a human or not. As a service oriented country this is going to put a lot of people out of work. What are people going to do? There are few manufacturing jobs left, self driving vehicles are gearing up to take all the transportation jobs. There isn't a whole lot left to do.
