Someday if there are experiments that can show it.. it's still a possibility that in Quantum Darwinism or Everettian, pointer states are primitives? This means if there are no pointer states. The universe wont be classical at all. Because there are arguments that they have to conform to orthodox quantum, meaning observations are primitives and not pointer states.. but this is believed simply because Quantum mechanics started that way? Or is there a theorem that pointer states can never be primitive and everything needs to be categorically traditional QM where the classical world is an a priori?
