I'm well aware of that. I guess you're disputing the "MWI is nothing
but the Schroedinger equation" statement that John Clark sometimes
makes.
As soon as you have self-location indeterminancy (or first person
indeterminancy, I think we called it here), probabilities march right
on in. And as soon as you have computationalism (and I would argue
functionalism), self-location indeterminancy marches right on in. That
was the point of Bruno Marchal's Universal Dovetailer Argument.
So the question is how would you do the MWI _without_
probabilities. David Deutsch is working on a possible solution to
that, although I'm a little sceptical he can make it work.
Cheers
