A phenomenologist myself, I am agnostic about different interpretations of what is indeed the same math, such as QBism vs Copenhagen or the Many Worlds. ...I don't know how anyone can say that Copenhagen, Many Worlds, and superdeterminism all make the same predictions.
I find superdeterminism interesting ...
The stakes are high, for if quantum mechanics is not a fundamental theory, but can be derived from an underlying deterministic theory, this opens the door to new applications. That’s why I remain perplexed that what I think is the obvious route to progress is one most physicists have never even heard of. Maybe it’s just a reality they don’t want to wake up to. ...
Really, think about this for a moment. A superdeterministic theory reproduces quantum mechanics. It therefore makes the same predictions as quantum mechanics. (Or, well, if it doesn't, it's wrong, so forget about it.) Difference is that it makes *more* predictions besides that. (Because it's not probabilistic.)
Not only is that false, but Many Worlds and superdeterminism are so absurd that there is nothing scientific about either one. They don't make any predictions. They are amusing philosophical thought experiments, but they have no "same math" as anything with any practical utility. They are like saying that we all live in a simulation, or as a figment of someone's imagination. Not really a scientifically meaningful idea.
I really wonder what Dr. Bee's conception of probability is, that she says these things. There is no way to make sense out of probability, consistent with her statements above. Maybe physics books never teach what probability is. I don't know how anyone can get it this wrong.
