One scary thought however is: once automation has progressed this far and there are enough mostly autonomous humanoid and/or military robots, what power does the suddenly jobless general population have against those who own and operate them, which will mostly be rich people - and the government, which is in many places made up of other rich people?

I'm not saying this is a likely scenario. But as far as I can tell, we will objectively be mostly at their mercy. And how merciful have they been over the last few decades?
