I'm not sure you are following me at all.

1. Have you presented any argument whatsoever that MWI is logically unfalsifiable? Where is that argument?

2. I am actually quite knowledgeable about Bayesian statistics. The mathematical formulation of quantum mechanics does NOT include any interpretation, that's why it's called interpretation in the first place. That you conflate Bayesianism with interpretations of QM is curious, as if Bayesianism supports any particular interpretation of QM, it does not do that! Bayesian vs. Frequentist debate applies to every application of probability theory. However, you seem to be, ignorantly, thinking that the epistemological interpretation in Bayesian statistics means that the probabilities in QM do not have an ontological character. This is wrong on so many levels. First, probabilities in QM are not identical to the wave function. You obtain the probability density function only after finding the square of the magnitude of the wave function right (by multiplying it with its conjugate)?. So, your statement is obviously meaningless, you are just another dualist talking about this religiously. Let me ask you: since you believe that , you also believe that there are non-physical things in the world, right? For Copenhagen and equally banal Von Neumann interpretations boil down to the claim that there are magical, inexplicable, non-physical "things" or "events" in the universe, along with what we consider to be real and physical (observations).

3. And have I said that this study supports MWI, or that MWI is my preferred interpretation? I did not. However, I do think that the notion of decoherence is much more scientifically plausible, as it does not contain vague, and unexplained pseudo-mechanisms like wave function collapse. The way I see it, "wave function collapse" is an inadequate attempt at explaining a real phenomenon, and it posits too much therefore it fails Occam's razor. It seems to be a behavioral description of a class of events actually, without revealing a consistent theory of "how", and that is quite suspicious in itself, however, yes, I anticipate that there would also be things that are incorrectly predicted by "wave function collapse". I do not find the rest of the Copenhagen interpretation problematic.

4. The issue of which interpretation is correct is the key to a GUT, therefore it has scientific significance. Good luck with starting from Copenhagen interpretation and obtaining a GUT! There are several plausible interpretations such as consistent histories, one of them could be true, but not Copenhagen or Von Neumann, which are fundamentally mysticist, it really is just medieval solipsism. Mystical stuff, especially solipsism, isn't physics. According to your celebrated Heisenberg, the particles aren't real but their appearance is real. This is just glorified stupidity, sorry.

5. I am equally suspicious about the everett interpretation of quantum computation, that quantum computers we construct harness the computational power of parallel universes. I suspect that as we build larger quantum computers we ought to be able to measure how much of this is true. Thus, perhaps this issue will be clarified during quantum computing experiments.

6. You also don't seem to understand that the reality of the wave function would not "destroy" Copenhagen interpretation, it would just change it slightly. Both observations and wave functions can be real in an interpretation. That subject is a lot more complex than you seem to think it is:

Philosophers of physics held many conferences on the subject, with apparently no real resolution, so if you just insist on this mysticist, semi-scientific interpretation go for it in your isolated space, but please stop preaching it to your students, and stick with math and experiments!
