The thing about quantum mechanics โ and one of the reasons scientists donโt like to talk about it philosophically โ is that if itโs true, you have to non-optionally accept at the very least one of these ridiculous ideas (and in reality, two of them*):
1) That determinism cannot be true.
2) That locality cannot be true.
3) That the many-worlds interpretation is true.
Themโs your options. Seriously. There arenโt any more. Now I am sure you can see why scientists are loathe to discuss the meaning of quantum mechanics, because no matter which interpretation of it is true it leads to absurd results. And since it appears to be a solid theory that makes very exact predictions about the universe, then absurdity is baked in. You cannot get away from it.
Since determinism in most formulations of QM cannot be true itโs a mystery to me and many others of a more philosophical bent why nearly all scientists claim the world is fully deterministic when the very foundation all of science is based on absolutely is not deterministic if locality is preserved (and if locality is not preserved, whoops, then no causality!).
*Due to the fact that recent experiments show that Bellโs inequality is violated in this universe.
