What is the future of CNC deep hole drilling technicians?

Deep-hole drills are generally used to process oil cylinders and other parts, and the relative application scope is relatively small. In the past few years, this kind of equipment has been used more. There is also the processing equipment for deep-hole drills, which are generally made by Texas machine tools. This kind of equipment is relatively cost-effective in some fields, but its versatility is much worse. I need to learn some other knowledge ~
