Sometimes, sometimes not. CNC (as someone noted) is just a control mechanism. For some use cases, the cams and levers of a World War II-era Screw Machine are faster and far more cost effective than a new, or even used CNC mill/lathe. There are shops out there that will buy up old automated machine tools and dedicate each machine to a particular setup or product that they make in bulk. That 60 year-old hunk of cast iron and steel might have cost an eyewatering sum when it was new, but because CNC is all the rage now, it's available for the cost of scrap now and it may still be as precise as the day it was built.
