There is less mobility in the work force because the computers are not simply displacing jobs, they are taking out the middle. Computers are good at routine cognitive tasks in the middling white-collar range, the desk jobs, the jobs that require keeping track of things, making arithmetic calculations. They are not so good at motor tasks, the blue collar jobs that require coordination, manual dexterity and sense-of-the-world adjustments. Computers can crunch numbers but they can’t drive a truck or make up a hotel room.
