Right, but how much support do these bots need behind the scenes. Somebody has to do maintenance on them, somebody has to be able to decide whether they're functioning properly, whether they have problems that need to be addressed, etc. Hence why I think there will still be need for workers. It's just the nature of work is going to be around making sure the robots are operating smoothly. You'd probably need a relatively small workforce, but I don't think you could eliminate it entirely by 2040.
