vanhees71 said:the very fact that proponents of a quantum-classical cut always agree that the cut can shifted arbitrarily shows that the cut is as unnecessary as the aether in classical electromagnetics.
No, it doesn't, it shows that quantum mechanics as currently formulated is an incomplete theory. A cut is required to extract predictions from the theory, but the theory does not tell you where to put the cut; practically speaking, physicists put it wherever it works best in making predictions for a particular problem.
