Most of these makers have factory tour videos that will clue people in to a lot of the important stuff that still requires manual work by someone who is at least a decently trained machine operator. Does any manufacturer just take the neck cut out of the CNC? All the good production makers I've seen have people who manually sand them on a belter for a last pass (primary reason for neck variability). A lot of things still seemed to get shaped by an operator using machines. It's not this "put wood in, done" process it seems to be made out to be.CNC machines just do some of the heavy lifting. You can’t put a piece of wood in a CNC and have a guitar pop out the other end.
the OP’s argument sounds like a rationalization of some sort.
