New jobs might materialize but who knows if they will be good jobs. Think of all the towns around the US set up around resource extraction or manufacturing that went away, and in its wake you have jobs like selling geekbars in the 7/11 to the other minimum wage workers and people scrapping along on the dole in the area. People living on the poverty line today while their parents bought a home and two cars on a single income from the steel mill a generation or two previous. Most of the population up and left.

How about when offices went digital? All the file runners, calculators, switchboard operators, secretaries, transcribers, etc. Where are they now? Probably not working good jobs in IT. Maybe you will find them bagging groceries past retirement age today.
