Disagreement about “what quantum mechanics means” is a philosophical problem, not a physics problem.
The job of physics is to build predictive models of natural phenomena, not to settle metaphysical debates about the “true nature of reality.”
And on that front, Quantum Field Theory - which superseded old‑school quantum mechanics decades ago - does its job extraordinarily well.
QFT predicts particle interactions with absurd precision, matches experiment to many decimal places, and underpins everything from semiconductors to MRI machines.
Whether philosophers (or physicists wearing philosopher hats) can agree on an “interpretation” doesn’t change the fact that the Standard Model works.
