It's inevitable.
Two saving graces:
1) There's already a LOT of 'dumb' hardware out there. And firearms are durable good. Very, very durable goods.
2) We're Americans, and try as they might, information sharing is still rampant and flowing free. There's a lot of people out there with mills, lathes, 3d printers, grinders, etc. All it takes is one mechanical engineer to make one blueprint and set of G-codes per firearm model to render the whole exercise moot.
