This is exactly the same problem of "mechanical engineers' job is to design parts, not machine them, so we'll take training on machines out of the mech eng curriculum." Result: fresh mech eng grads do not know how to properly design parts because they have no idea how they are machined.
How do they solve this for mechanical engineering? Or is it an ongoing problem?
Vertical integration is valuable at many different scales
Surely they're made on CNC machines now? (well, since the 1970s)
Should ontogeny recapitulate phylogony in the trades? Ie, should we teach historical techniques and graduate to modernity?
