The "Shut Up And Calculate'' people should note that Many Worlds is the simplest interpretation that explains all current observations with no additional bells or whistles required. > > *The MWI is an instance of that, where there is a splitting of the > world according to different quantum amplitudes and an observer records > data along two or more tracks.

I don't know how much more you demand that an "explanation" provide.
