Only to the extent that MWI is actually a position. My understanding of MWI is: shit happens, and there's no need to understand why specific shit happens because all shit "happens" (by a definition of "happens" that carries basically no meaning) and you should be happy just to prove that the shit that happens is among the full set of shit that could happen. It's the "don't worry your pretty little head over it" theory of reality.

Here's the best poem ever written, or that will ever be written:

    Roses are red
    Violets are blue
    MWI stinks
    And so do you.

Don't think it's that great? Well, that's because there exist other versions of me that wrote different words up there, and you just happened to read a version that wasn't that great.

I hereby accept my position as God Poet of the Universe.
