Main Question or Discussion Point
If MWI and collapse-theory are both possible interpretations of QM, then both of them are not a fact, right? If MWI is a fact then collapse isn't and vice versa, you could say the least. So, shut up and calculate, i.e. the minimal interpretation, makes no inference about the realness of these two interpretations. So could I then be allowed to suggest many world are not really 'many' worlds, but rather mathematical semantics?
