Not looking to make this political, but last I checked, robotics repair paid way more than delivery driver. Programmer more than that, and automation engineer, even more. There'll be lots of good jobs in manufacturing, programming, and maintaining those drones.
Close a door, open a window...
I dont disagree... but my point is not about payscale... its about the number of jobs relative to the size of the population. UPS has something like 100,000 drivers out on the roads and a similar number of trucks. If we replace all the delivers with drones will you need 100,000 repairmen and engineers? probably only a fraction.
Just like when we automated factories we replaces 100k's of assembly worker jobs with 1k jobs running the automation.
