Sure but then aren’t you just glued to the computer doing 3D design and letting the machine translate that to reality? Isn’t the point to build stuff with your hands?
You need to know a lot about how to use a CNC such as tooling selection, milling strategies, setup, work holding, etc. that dramatically affect the result. It's not as simple as 3d printing, but yes obviously it's more technical and less 'analog.'
