I think the order of concerns is also telling.
Primary reason why it's bad: Increase risk of runaway superintellicence, XRisk, etc etc
Secondary reason: Oh, it will also make most people unable to have a living wage. We should probably do something about that, if it doesn't strain the economy too much.
The dehumanization of everyone who will still have a job? Nah, not a problem.
Though I think this dismisses the potential of people to organize, especially in jobs like those. This is why I'm skeptical that future will happen as easily as he is warning here.
