The other worry is that the owners of the robots will get all the money, leaving us starving in a howling wasteland. Fortunately, a rather decent economist, William Nordhaus, has looked at this. If the robots really do start doing all the jobs and the capitalists get all the money, then the capital share of the economy will asymptotically approach (jargon for get ever closer to but never reach) 100%. That’s our starving wasteland scenario right there. Except exactly the same process means that real wages will have to be rising at 200% a year at the same time. For we’ll only use the robots if they’re more productive and greater productivity in the economy means, by definition, higher wages. Which isn’t, when we come to think about it, something likely to bring us peons out into the streets in revolution nor actually something that we’d worry about very much.
