Don't be scared, the future actually looks oh so very bright. Those old school jobs will soon be replaced by "fleet managers," but more importantly, the technology sector will continue to blossom in America. Engineers, designers and tech savvy individuals will be in maximum demand to ensure our economy thrives under those conditions demanded by the modern world. With capitalism, you must evolve, or be irrelevant. Go Tesla! No fear..
Here is where I don't think people understand the danger.
First Principle 1: The purpose of a machine is to multiply the "work" (in an economic sense, not necessarily a physical mechanics sense) output of a human.
For a mechanical machine, that means multiplying what that human can do, e.g. a sewing machines allows a person to sew say 10x what a normal person can sew. For a computational machine, that means multiplying what a human can do with their mind. A "fleet manager" can manage multiple trucks/buses. If 1 fleet manager can manage 100 vehicles that used to require 1 human drive each, what do the 99 displaced human workers do? The new jobs created by leveraging technology will be far less than the number of jobs eliminated by that tech.
When routine agricultural jobs were eliminated in the 19th and early 20th centuries via mechanization, people could still find jobs in factories. When routine factory jobs became increasingly automated, there were still plenty of office jobs and jobs where human hand/eye coordination could not be replaced. Now with even routine office work and traditional hand/eye coordination jobs under threat, where will people go?
First Principle 2: Not everyone is smart enough to be an Engineer, designer, or tech worker.
First Principle 3: Idle people get into trouble.
Do we really want hordes of idle people to become "irrelevant" to society? Jailing people en masse works very poorly today, and I doubt it would work any better in the future. People without work and without purpose will resort to crime to survive.
I love new technology, but I also find that societies in general do not really consider the implications of what technology will do to the fabric of a society.
