I expect if you have an inclination to do commerical work, CNC will be pretty much required to be economically competitive for lots of jobs.
For home shop use, however...who cares? After all, there are home shop types beating out ornamental metalwork with forge and anvil using techniques that haven't changed much since the Middle Ages. The main idea is to have fun. If you can have fun with your hand-cranked lathe and milling machine, what other consideration is there? You don't have to please anybody except yourself.
Even for a commercial shop, it's not absolute (yet). There's a small one-man shop a few miles from me. He doesn't even have DROs. He manages to make a living doing an assortment of jobs, doing niche work that he can still do cheaper than a CNC shop that has a greater overhead.
