But this implies that a human observer is needed for something to be a measurement. The fact that the outcome of the measurement is physically available in the universe is not enough. Would you agree that, knowing the outcome of the quantum eraser experiment, the Copenhagen interpretation implies that observation by a conscious entity is necessary to define a quantum state? The Copenhagen interpretation seems to require two magic steps (consciousness causing wave collapse and "pure randomness"). It seems to be a more extraordinary claim than the MWI. Also, CI + the quantum eraser experiment implies that stuff doesn't exist when no one is looking. Am I wrong (honestly asking)?
