    QM is the laws of physics that best explains what we see. I think that
says it all. I should point out that there is really no summation involved,
especially not a sum over worlds. There is just -i hbar d/dt psi = H psi.
Of course, you could write psi as a sum of orthogonal functions and you
could choose nearly decoherent such functions.

    In the computationalist view, there is a wavefunction, and it implements
computations. These implementations may resemble those that would be
produced by classical mechanics, modified by interference terms that may be

    You still don't know what computationalism means? It means that certain
computations give rise to consciousness. It does not explain behavior at
all, and does not allow zombies.

    Dunno about "explain", but by definition it does assert that there would
be consciousness.
