There’s also an “outside the box” problem: in a non-local universe, it may be impossible for you to compute the trajectory of something without perturbing it, eg, because you slightly jiggle all of the electrons everywhere. So the co-trajectory of your computation and the particle only ever agree by so much: attempts to increase the accuracy of the calculation kick the particle around, rendering it inaccurate. There’s deep senses in which uncertainty emerges from being part of the system you’re measuring, in any paradigm.
