Earlier quoted context omitted.
Manufacturing jobs are disappearing but real manufacturing output has actually been steadily increasing over the last 50 years.
Very true, but still not a great place to be. Whether the boogeymen are robots or chinese workers, not having a market for manufacturing labor is a bad position for an economy.
I understand an economy that does not produce any of its own goods is in a jam -- it's an external critical dependency that can be wielded like a club against you. But if you have adequate internal production, what does it matter if it's done by humans, robots, or hyperintelligent cyborg orangutans? It may take a generation or so, but the people who would have been manufacturing labor will be absorbed into other markets -- or should be, as I understand it.
