Thanks you for your reply. I will think more deeply about what you say, but unfortunately I have to work :) A quick reaction follows. > Materialism vs. idealism is not the same disagreement as realism vs. non-realism. True, but they are deeply related. Non-realism is only weird if you assume materialism. I'm not sure idealism is sufficiently well-defined that one can say that it preserves (or not) your definition of CFD. > The quantum interpretations that give up CFD are a fundamentally new paradigm, and a ridiculous one IMO. How do you interpret delayed-choice quantum eraser experiments? This is not a rhetorical question btw, I am 100% open to reading your take. > For instance, the mathematical universe hypothesis is a new form of idealism, but it preserves CFD and so is realist. Only with Tegmarks's later-added assumption that only objects describable by decidable computations are real.
