I've always thought about this. It is coming.
In college I saw the Sony dog robots play soccer and the robotics professor putting it on said that computer scientists, engineers, and others in the robotics field hope to field a team of robots that can beat the FIFA World Champion by 2050.
We will be able to create these one day. We'll create them in mass for cheap. They'll be everywhere.
Construction workers? Plumbers? Carpenters? Trash men? Postal workers? Doctors?
Why would Walmart hire anybody that can only work so many hours when they can buy one of these robots, load Shelf Stock 2.0 into it, and get 100% productivity 24/7/365?
It's 3 am and need a plumber? Roto-Rooter will send out a robot to do it. No need to pay a human overtime that might not be able to do their job correctly due to lack of sleep.
Restaurants can stay open 24/7 with their robot servers and cooks.
Doctors and nurses will be replaced by robots with detailed medical information, records, and files.
Convenient stores can hire a robot to work full time.
The banks will no longer need to close as robot tellers can take care of things. Also there will be no worries for the bank as accurate counting and possible theft don't happen with a robot.
Uber? Taxi? Somebody will buy a car and a robot, or a self drive car, and people can party all night.
That also means robot bar tenders.
Computer technicians? IT? Who knows a computer better than a computer? Robots, unlike humans, can also plug into the system to help find the problem faster.
Airports can replace all their flight crews with robots to run flights all the time. Most new commercial airplane can take off and land themselves, if needed, so a robot by that time will be standard.
Millions of blue and white collar jobs will disappear overnight. What then?
