"It seems to me that it is self-evident that most low-skill labor, at the very least, is in the process of being automated and is therefore going to be unnecessary. "

I'm not sure this is restricted to low-wage labor. There are plenty of low-wage jobs that are just complex enough to make automation more expensive than wages for the near future. Driving is a good example here (for now).

And there's plenty of high-wage jobs which are quite automatable - accounting (TurboTax), financial management (wealthfront/betterment), lots of software operations work (AWS tools), etc.
