I resonated with Jeff Sontag's plaint regarding the QM dilemma:
does the moon cease to exist when I stop looking at it?

I prefer the model where the wave equation merely ecodes our
state of knowledge (or lack thereof) of the system under
observation.  The act of observing then supplies another
clue which may be sufficient to resolve some element of
uncertainty about the state of the system.  That quantum
increment in information is reflected in the collapse of
the wave function--the disappearance of our ignorance.

(I believe Matthew Wiener once advised me that the above
interpretation of QM is called the Copenhagen view.  I
find it more plausible than the Many Worlds view.)
