The problems begin when we apply our macro way of thinking to these
teeeny little thingys. In QM, even the notion that something goes from
"here" to "there" is suspect. The real confusion begins not with the
wave functions but in our habits of visualizing them as waves at all. If
one adheres to the notion that a wave function is strictly a means of
calculating probabilities of events, this confusion vanishes. Like the
confusion that "soul" brings to the information models of mind, most of
the interpretations, from the Copenhagen Observer to Everett's many
worlds appear to be unprovable, and per our friend Ockham, not needed
either, save for our monkey brains which see thru monkey eyes.
