Replace "dumb" with "extremely inefficient and not ideal"

A blockchain gets created where all the profits of automation get distributed evenly as UBI. Problem solved. I'm not underestimating the amount of greed in the world. I'm fully aware of how badly automation can centralize wealth distribution.

However, at the end of the day, if the rich want the poor to keep working as slaves, the poor have to have something that the rich want in the first place (a tiny bit of money and/or the ability to work). If machines are doing everything what's the point of having poor slaves? Perhaps there are plans in the works to kill a few billion people off when they've outlived their usefulness? Who knows.

Have you seen the movie Kingsman? The logic tracks.
