In his speech at the World Government Summit 2017 in Dubai a few days ago, Elon Musk seems to have clear ideas: a form of guaranteed universal income is absolutely necessary, or globalization and automation will seriously jeopardize all our social fabric and the sense itself that we attribute to our existence. Here is the transcript of his speech.
There will be fewer and fewer jobs in the world that robots can't do better than us. I want to be clear: these are not things I want to happen. These are things that I believe, unfortunately, will probably happen: and if my predictions are correct, and they probably are, we must think carefully about what to do. I believe that some type of universal basic income will become necessary. The production of goods and services will be very high: with automation there will come a real glut that will make many products really cheap. The question we must ask ourselves now is: how will people who today attribute it to work find the meaning of life? If there is no need to work, what will be the meaning of their life? Will they feel useless? This is a much more serious problem than those posed by automation.
The whole chat (in English) is quite interesting, and goes through many topics that are the subject of Elon Musk's activity, from space exploration to alternative transport.
