But if you amplify the micro superposition and throw in a cat, you get an absurdity. Maybe Schroedinger was *also* trying to show that the interpretation of *micro* superposition is not correct. AGYes, I think he did. But he was wrong about that. Bohr saved the theory by declaring that there was a classical world and a quantum world, which worked pretty well because everybody's intuition about the Heisenberg cut was about the same. BrentI don't see how Bohr saved the theory (of superposition?) by making that declaration. Isn't there general agreement today that everything is quantum? AG
There is now, but "Shut and calculate" produced huge advancements in understanding physics, chemistry, and biology and produced the solid-state electronics revolution - without metaphysics getting in the way.
