>Enter STEM. Instead of assembly-line workers, customer service reps, and bank tellers, we will soon all be the scientists and engineers designing and servicing the grandiose machinery that now does most of the actual work. With the problem that the "automated" infrastructure has incredibly high initial capital costs and incredibly specific skills requirements. Just think how many software frameworks are used for a typical complex product that really does something useful: call that N. Now, where do you find 100 engineers trained and experienced in all of N different things?
