Back in the 1990s, Savage had a program that brought gun writers into the factory and let us have a whack at running the machines (under close supervision, of course). I had a chance at it, and came out covered with oil and filled with new knowledge, to wit: It takes both skill and dedication to get good results out of a drill, or a milling machine, or a grinder, or anything else. The best machinist can't get proper work out of worn-out equipment; the best equipment will not produce good results if the guy running it is hung over, or indifferent, or is in the middle of a bad divorce. What CNC does, in theory, is remove the human element. In place of machinists, you have computer programmers, and once they punch in the numbers, the rest is automatic. However, you have to have a programmer who knows what he's doing. This work requires some pretty rigorous math, and I'm told that people who are up to the job are not in abundant supply. So if the program isn't quite right, the parts will not be quite right. They can probably be assembled, and may work some of the time or most of the time, but that will be the end of it.
