That was my first thought too. However, if you don’t have an income because you can’t provide economic value to society, how do you purchase a robot? Further, the robot technology, at least for a while, may be proprietary, closed source and expensive for some time. And even if they do become cheap, and your robot can take care of your house, kids, etc. how can you afford food, gas, electricity (physical goods) if you have no income and no land? Robots could automate lots of your tasks without being able to provide you with economic value. Just brainstorming out loud
