'A Universal Income is Not Such a Silly Idea'

Tim Harford argues that "A universal income is not such a silly idea". His argument ends with:

... There is an alternative way to look at all this: an increasing number of economists are beginning to worry that technological change may make large numbers of people completely unemployable. In short, the robots are coming to take our jobs. These concerns have been wrong before, but perhaps this time really is different. If so, we’ll need an economic system that can cope when lots of people have no way to making a living. I wonder if everyone has a basic income in Star Trek.
