A wide range of possible interpretations of quantum mechanics were considered at the Vienna symposium on Emergent Quantum Mechanics, as Michael Brooks reported (14 November, p 14). Howard Wiseman and Jan Walleczek both spoke of the importance of keeping all possible interpretations in mind. It seems to me that these quantum theories are all in a state of superposition. With our current understanding of quantum mechanics as a "black box", all of them are possible. By opening the box and making an observation, the wave functions for these theories collapse into the one underlying quantum theory.
