The theory does not predict that the superposition plays an important role. That is simply contradicted by the two slit experiments. No interaction does not imply no statistical interference, or QM would not makes any sense at all. Dirac considered the principle of superposition as the main quantum feature. “Parallel world” is the same as superposition of state/histories.
