Great point. This could be one of the non obvious social consequences of rapid manufacturing. At least if I think of the IT revolution, then in some sense system programmers replaced a lot different specialties, like delivery boys ( by email), accountants ( at least the half that was double checking the books fifty years ago) and type setters. And in a addition people with domain specific knowledge were enabled to use this knowledge efficiently with computers.
