Oh, I know exactly what you were trying to say, but it's in no way analogous. Your analogy is bogus.

And sure, you don't need a master woodworker to operate a CNC machine, but the that person is still highly skilled, it's just that the set of skills is different: they need to be able to program on some level, and they also need to have an understanding of the materials they're working with. Go away for a bit and so some research on what somebody who operates a CNC machine actually does.
