I don't see anything wrong with using CNC manufactoring - it enables consistent production at a much more affordable price. Welcome to the industrial revolution where you, too, can afford lace, and people no longer go blind making it by candle-light. So there are manufacturers that will sell you "better instruments" at a price you can afford. How is that anything but a good thing? If it doesn't make any difference to the end result, what virtue is there in making the job harder for yourself than it needs to be? As a trivial analogy, I learned to touch-type in 1987, on one of those newfangled electric typewriters. One of the things we were taught was how to centre a line, by counting the number of characters in it and then calculating the offset. Some years later, I was harangued by somebody else who'd learned to do this, who was quite upset about these newfangled word-processors doing it automatically for us. There was no craftsmanship involved, and the skill we'd learned was now useless. I smiled and nodded. Our customers didn't care how much work we put into it; they just noticed when the text was off-centre. Disclaimer: I do have the scratch, and I do have a couple of boutique instruments, as well as some clearly CNC-made ones that cost a fraction of the price. I don't disdain either side. What I paid for in the boutique instruments was higher quality and attention to detail, and getting exactly what I wanted, instead of settling for "close enough" from the production-line versions. I didn't ask, and don't really care, how much of their construction was automated and how much was done by hand. At that price, I expect luthiers to use whichever approach gets the best result.
