Is it possible that QM randomness is just lack of information that could change to determinism in a new refinement of QM? I understand (I think) that QM requires a certain randomness and is not just a lack of perfect knowledge as is the case in Classical Physics. Isn't it possible that with more knowledge in the future about how the quantum world works that the predictions of QM today could still be upheld but the underlying math changed in a more deterministic manner? For instance Classical Physics explains our everyday world. So does GR but in a more precise way. QM explains the quantum world but a future refinement of the theory could keep the current results (would have to) and offer more precise results using different math based on future discoveries of how things work. Just as the Pilot Wave theory (in my limited understanding) does that for QM now. The bigger, subjective, question is how likely is it that the more "mysterious" nature of QM might go away in the future with more knowledge of how the quantum world works? It seems to me there is a very fine line between randomness, a chaotic system, and a deterministic system with less than perfect knowledge.
