My boss's wife is a Cobol programmer. Apparently there is a niche market for people who can maintain code for businesses that want to keep using obsolete technology. That is, of course, the exception rather than the rule.

Did you think about how the truck drivers who abandoned their CBs might be the next things to become obsolete? Long haul trucks look to be the first major use for self-driving vehicle technology. I read a truckers review of the new Tesla design for a self-driving truck. The first ones will have a cockpit for an operator, but the driving will be done by the truck most of the time. The reviewer thought it looked like a rotten design because the operator seating and mirror placement were designed for aerodynamics rather than visibility. He didn't seem to get the idea that the human was only supposed to be there briefly while they proved that humans are a liability when it comes to operating machinery.
