People will have to adapt to a new way of life. We are going to move into a world where full employment means 50% of people don't work, because there is nothing for them to do. Like the computer, the cost of everything will begin to decline rapidly when general purpose robots and automation take over human tasks. The UBI equation may well balance. When there are no human costs the only cost is energy. In theory, you will need far less income. Honestly, I'm excited to see what happens as it will happen in my lifetime. 30 years ago we had the first general purpose computers. Look at where we are now. Today we have the first general purpose robots. Imagine where we will be in 30 years. It's hard to imagine. Drivers, construction workers, doctors, lawyers—it's all going to be dramatically different 30 years from now. Forget the US. All those jobs making everything from iPhones to t-shirts will also be at risk. When you don't need specialized equipment and you can buy a robot that can make t-shirts for a few thousand dollars you don't need the human anymore. If not UBI, then what? What do all these people do?
