What needs to be explained is quantum mechanical behavior, the wave
function

is just a way to perform quantum mechanical calculations and it's not the
only way, if you don't like it you can use
Heisenberg

Matrices and you'll get the same answer. MWI, Copenhagen, Transactional,
Pilot Wave etc are all attempts to give a physical intuition about what is
going on and not just crunch numbers. Many, perhaps most,  ph
ysicists
 don't care about that and belong to the "shut up and calculate" school;
assuming you're not a member of that school which physical interpretation
do you think is less weird than the MWI?

True, but if general purpose quantum

computers are possible then there is a way to tell if Copenhagen or MW is
correct. Yes that would be hard to do but that's Copenhagen's fault not the
MWI fault. Copenhagen says conscious stuff obeys different laws of physics
than non-conscious stuff, consciousness can collapse the wave function but
non-conscious stuff can't. MWI says both obey the same laws of physics. So
to tell who's right you need an AI that operates on quantum principles. And
that would be very difficult to make but it's starting to look like it's
not impossible.

True, and yet 
both 
Schrodinger's
W
ave
 Equation and 
Heisenberg

Matrices are 100% deterministic, one of the many weird things about quantum
mechanics.
