I am interested in interpretations because I want to see what the machinery of the universe looks like. I think it is important to discuss interpretations that show promise to advance our understanding. My motivation for my question in this thread was to understand if there was a real challenge to the non-local causal interpretation. I think the challenge that PeterDonis brought up about field operators in QFT having to commute is a good challenge to this and something I plan to learn more about.Interpretations are simply assumed for convenience, aesthetics, philosophical, or personal reasons. I am not really interested in interpretations.
[Edit: that is field operators of space like separated events commute]
