Oh my god!!! Sorry to react like this... Other people already commented that... That is sooooo much disconnected from reality it shows you never went to a factory floor. You never seen anything being produced in mass scale. Even the poster wall robot arms doing welding work need hundreds of people taking care of their set up, maintenance and much more. And those are complex machines. Even simpler machines such as steel presses that take in steel rolls and make steal parts of all shapes and sizes (e.g. car breaks, fridge doors, anything with steel actually) take a huge amount of set up work, management and maintenance. In Germany (which I know well) you see plenty of kids (18yos) in factories learning all these detaild skills from older workers. Takes them some years to become good and they are very sought after. Companies do worry if can get good high school kids to take their aprentiships. This has ZERO to do with higher math or bachelor's degree engeneiring education.
