who makes the robots, and automated factories?
my PC doesn't even do what i tell it to alot of the time.
Let's examine that one! Three hundred years ago humans and animals did the work of farming and one person could farm a couple acres. Around the time of the American Revolution something like 85% of people worked in agriculture. Then came the Industrial Revolution and automation. Fast forward to today, circa 2019. According to my research only 2% of Americans work as farmers. The work that used to take millions of people is now done by about 790,000 people. Did all those farmers switch to making tractors? No, they did not.
New jobs did open up to replace farming. Some of them are what have been called "bulls**t jobs", just kind of make-work. Others are building houses, paving roads, etc. Increasingly though they're in 'service jobs', not building anything. America has largely switched to being a 'service economy'. Selling lattes, flipping burgers, listening to people complain about problems with their credit cards, etc. And those paving roads and building houses also suffer from increasing automation.
So who will make the robots? For now, people. But it doesn't take a lot of people to make the robots, and those that maintain the robots will need advanced skills. Tomorrow? The robots will be building the robots. Why? It will be cheaper. Americans don't so much worship God as they worship capitalism. That means a race to the bottom with little thought about the social impact. When a self driving truck hits the point where it's marginally cheaper than a driver, that driver is out on his butt. Every. Time.
At the time of the Industrial Revolution machines were simple, stupid. They could do only the simplest of jobs; digging holes, processing cotton, hammering a spike. Computers changed that ushering in the Information Age. Now computers running robots can do very advanced jobs.
Eventually they'll do more advanced jobs. Right now current diagnostic software is diagnosing illnesses more accurately than doctors. We've long since passed the point where humans had a chance against chess playing computers. No, in the future even white collar jobs will be on the chopping block. Already some finance firms are replacing some analysts with algorithms. Machine learning is creating computers that can read and 'understand' medical journals, allowing them to be more up to date than any human doctor ever could be. A computer doesn't sleep, it doesn't eat, and it can 'read' 24/7.
As computers become more advanced they'll inexorably replace many human jobs. Already computers do most of the flying. Computer-driven cars are in their infancy but already have less accidents per mile than human drivers. They never get tired, take sick days or go on strike.
I don't see any way to put the toothpaste back in the tube now, do you?
