This is not unprecedented. 40% of people worked on farms in 1900, and that went down to 1%. Losing 10M jobs to automation, and another 3M in the energy sector over 10 years?? 9% of the labor force? So if 25% of them retire over 10 years, and 25% find new jobs, unemployment would rise from 3.7% to 8%. I don't see how this is something to get excited about. And since this is all due to increased productivity (same economic output with less labor), we could shrink the labor force by those 13M jobs and have the same economic output - perhaps people would retire early. Or, the same number of people could be employed, but work 35 hour weeks for the same pay instead of 40 hour weeks. Increased productivity is a good thing.
