Is a robot tax, or even an AI tax, really a good idea?

Critics of such an idea have, in the past, argued that any tax on a machine, be it a robot, a car or an AI tax, would be anti-business -- but then it would be stretching credibility to suggest Bill Gates is anti-business. "You ought to be willing to raise the tax level and even slow down the speed of automation," said the co-founder of Microsoft. He warned: "You cross the threshold of job replacement of certain activities all sort of at once. If you want to do [something about] inequality… government's got a big role to play." There are multiple problems with the idea.
