The reality of automation in America is that the value created by automation is captured exclusively by the large corporations that own the machines and their senior executives. So whilst the theory is you want automation, in reality it provides only risks to the person whose job you're automating.

Because from a realpolitik/game theory perspective if your existence doesn’t contribute any sort of value to others/society there’s little incentive for others/society to keep you around. And that always ends in a very ugly way.

There is a built-in self-limiting mechanism for this. As development level increases (and coincidentally the number of workers required decreases) so does human fertility. Birth rate in the US is 1.77, well below the replacement rate of 2.1; Canada is 1.5, Finland is 1.49, Japan is 1.43. The workers are disappearing peacefully already.
