Is there an interpretation of quantum mechanics, which could make a difference to future calculations and results? Maybe an interpretation which could rewrite and simplify the algebra? Or one which has new testible results which when correct would change the quantum mechanical equations to make them more precise or simpler? I mean there are popular interpretations like many world interpretation, but it is hard to see why one should put up a theory like this which is neither more powerful nor more intuitive than a copenhagen interpretation. Also Bohm might be easy to grasp for the human mind, but result-wise it only complicates things?
