This is moving beyond the original point, but since we're here...
When increased efficiency kills jobs, the now jobless need to move onto some other form of employment. We saw this happen in migrations from farming to factory jobs, and now from factory jobs to service jobs. That area is safe for now since it's still hard to increase efficiency in services such as grooming, food preparation, entertainment, driving, and yard trimmers, compared with industrial production.
So there's still a certain stability in the current system that is not disrupted by emerging efficiencies, but that won't last forever. Eventually, even the services industry will become efficient, at which point the trend of jobs becoming scarce will accelerate to the point where it becomes impossible to employ everyone, unless you start inventing "busy work" jobs or change the work-to-live dynamic.
I'm neither calling it good nor bad; I'm just highlighting the need to come to terms with it, because it will come regardless of our preparation.
