The problem is that any hidden variable resolving quantum indeterminacy would have to be non -local, i.e. able to propagate itself faster than light, which would also violate our understanding of the world quite a bit.
I find it very intriguing that a "speed of light" emerges automatically in Conway's Game of Life. It's not built into the system, but shows up from the convolutional update rule.
More importantly, I'm skeptical towards non-locality because it is an extremely strong assumption with very weak effects: the only place it really shows up is in post-correlations between measurements of previously entangled systems, which notably cannot transfer any information faster than light (in fact, they require classical communication to even be noticed). Moreover, the only way to get entangled systems in the first place is through local interactions.
By believing in non-local hidden variables you get a deterministic universe with a mysterious, otherwise undetectable ether that instantaneously notifies quantum entities that they should update their behavior. By not believing in them, you get rid of the only n on-local "phenomenon" in physics (really, more of an interpretation) but you have to accept that some things are fundamentally random.
Easy choice, if you ask me (or most of the physics community).
Are we discussing science or public relations?
