Your comment clarified exactly what is so willfully foolish about this whole enterprise. "he wants a future where everyone has vast knowledge and a wide set of skills, and everyone has his own CNC multimachines, robots, all that" It is a nice fantasy to imagine everyone everywhere being self sufficient, but unlike the movies, a single person does not have the time nor the mental capacity to become an expert at everything. Specialization begat the modern world (and vice versa). Mao had a great idea to make everyone self sufficient by forging steel in their back yards to instantly industrialize. No one knew what they were doing properly, so you got massive quantities of nearly useless scrap, fueled by wasting previously productive inputs. The parallels are striking.
