Some people seem bothered about this'more' part, especially if it's not obviously accessible (althoughI'd debate this being the case with COMP).I'm not bothered, but neither am I convinced. The branches of theMWI are not obviously accessible and in fact they are not accessibleat all. I wouldn't say that rules them out - but it doesn't countin their favor.

`The branches comes from the superposition, and their linear contagion`

`must add something to QM (like the collapse), and this can be made`

`only by assuming that something (measuring apparatus, macro-object,`

`consciousness?) does not obey to QM.`

`With comp, things are even more simple (conceptually): the (finite`

`pieces of) parallel computations exist like prime number or total`

`computable functions exist, in a weak common sense of mathematical`

`existence, and the statistical interferences comes from the first`

`person indeterminacy, and the shapes it has to take with the self-`

`referential correctness constraints.`
