Of course, this is the refrain of technology's cheerleaders. Jobs don't disappear. They just change. Nimble people with can-do spirit can always find a new one. And on average, the jobs pay better and better.
Life gets easier and easier.
Actually, I'm one of technology's cheerleaders. Forced to choose between hunting buffalo with a bow and arrow and microwaving a cheese-steak hoagie, I'll take the sandwich. On balance, progress does make things better, at least materially, for most people. But the costs are real. Converting someone from a teller to an ATM servicer is not easy or cheap.
