George Musser identified himself as the latest promoter of the delusion started by John Bell, the delusion saying that the world has to be "non-local" ...Yes, and that is how the quantum mechanics textbooks have explained it since before EPR, Bohm, and Bell.
The truth is just the opposite one, of course. Locality works perfectly – at least in non-gravitational context. ...
All the differences between classical physics and quantum mechanics are consequences of the nonzero commutators in quantum mechanics i.e. the uncertainty principle. There are absolutely no other differences between classical physics and quantum mechanics. That fact also means that whenever the commutators between the relevant quantities are zero or negligible, the difference between classical physics and quantum mechanics becomes zero or negligible, too.
The uncertainty principle is the actual reason why it's inconsistent in quantum mechanics to assume that the observables have their values before they're actually observed.
Here is a new paper on retrocausality in quantum mechanics, and the authors keep talking about how they want to believe in "realism" and reality. That means that physical systems have their values before they're actually observed. Quantum mechanics shows that observables cannot have their values before observations, but realism is the hope that the state can be fully described by other variables before observation.
So realism is not a belief in the real world, but a believe in a mathematical abstraction of reality. This word usage seems peculiar to me, as I would have said that I believe in realism until I found out what they mean by the term. In quantum mechanics, realism has been a dead-end for 80 years.
