And yet it proclaims the issue settled in favour of MWI and argues of how wrong science is for not settling on MWI and so on. The connection - that this deficiency is why MWI can't be settled on, sure does not come up here. Speaking of which, under any formal metric that he loves to allude to (e.g. Kolmogorov complexity), MWI as it is, is not even a valid code for among other things this reason.

It doesn't matter how much simpler MWI is if we don't even know that it isn't too simple, merely guess that it might not be too simple.

edit: ohh, and lack of derivation of Born's rules is not the kind of thing I meant by argument in favour of non-realism. You can be non-realist with or without having derived Born's rules. How QFT deals with relativistic issues, as outlined by e.g. Mitchell Porter , is a quite good reason to doubt reality of what goes on mathematically in-between input and output. There's a view that (current QM) internals are an artefact of the set of mathematical tricks which we like / can use effectively. The view that internal mathematics is to the world as rods and cogs and gears inside a WW2 aiming computer are to a projectile flying through the air.
