One of the most critical aspects of engineering is making it so advanced high tech things can be manufactured by the least skilled and least number of skilled people possible.
Don't confuse that with the workers not being skilled - many are, but just like good software, you want your designs to run well even when executed by the worst hardware.
Actually engineering often means need more skilled workers as the unskilled work was replaced. 1 person running the machine who understands more of the engineering as opposed to 100 with a saw.
