Much attention is spent on the job-loss implications of introduction of automation to improve productivity. Meanwhile, automation is also used for job-preservation of older workers in outdated yet still essential practices, and this too has some unfortunate implications for the future. Eventually the simulation of an earlier age will fail catastrophically in the fact that that age no longer exists. Alternatively, eventually we will run out of older workers who can work in that simulation.
An economy of automated engineering and automated operation presents a new burst requirement on human labor. We need a labor model that can rapidly dedicate people to solve emergency problems caused by automation and yet that automation is essential for continued operation of the economy or for avoiding some future disaster.
