If I am correct in this, then all those philosophers who try to solve the quantum riddle by trying to provide an alternative interpretation of the current theory which leaves all laws of this theory unchanged are wasting their time. Those who are not satisfied with the Copenhagen point of view must realize that only a new theory will be capable of satisfying their demands (Feyerabend 1962b, 260, fn 49).The paper notes that John von Neumann said something similar in 1932.
Feyerabend had a lot of goofy views, but he was right about this.
I mention this because there are a lot of people today who admit that quantum mechanics is quantitatively correct in the sense that it makes very accurate predictions, but argue that the Copenhagen interpretation is flawed, and we must find a better interpretation.
Dream on. It's okay if you prefer QBism or consistent histories or decoherence, as these are just minor variations on Copenhagen. Those who attack Copenhagen as untenable really have a problem with quantum mechanics, and no interpretation is going to make them happy.
This was all recognized by experts in 1932 and by informed outsiders in 1962. Today's Copenhagen deniers are going against what has been conventional wisdom for a long time.
