You bring up a good point in that simple and repetitive tasks are necessary for many professions. But you also point out that the more we train towards these tasks, the more we expect living, breathing, dreaming human beings to behave as robots. This is neither healthy nor wise. The fact of the matter is that our current system is set up such that we put profit over human lives. A worker can drive a robot and such remotely. This is still a job that requires similar repetitive tasks but doesn’t risk the worker’s life to black lung, mine collapse, and other things. However, the cost of that worker’s life is still cheaper to the company than to replace him with an actual robot. That’s messed up in my view.
Anyway, back to education, I think workers should at least be able to fully understand why they are doing the actions they are. Why is that golden rule the safest way they can do things? People will remember safety rules better if they have context for its application and know why a rule was put in place. I think there is probably a spectrum for how critically people need to think for any given job, but currently, we need a lot more of the critical thinking to help prevent the giant ethical case studies we keep seeing pop up (Tesla, Volvo, Boeing, any HydroFracking company, BP’s many oil spills, etc)
