I remember sci fi stories where robots did all the work and people relaxed. But the reality is in a capitalist society the goal is money (and low social programs/taxes). Which means as bus drivers, taxi drivers, welders etc are replaced, there will be far fewer jobs for the average person and decades from now there will be a few very comfortable people and many many hungry peasants, even (especially) in the US. It makes me worry for people. There will need to be change. Hopefully common sense (and benign government) prevail rather than revolt and violence. This is not a tomorrow thing – it is a 22nd century thing.
