You may already be living in all of these universes, Hal, but I would rather
in mine, for the moment, if you don't mind!

Even in a "plenitudinal" or "platitudinal" metaverse in which all the
conceivable laws of physics are realized somwhere, there is no call
for all the interpretations of quantum mechanics to be "true"!
Interpretations of QM are not laws, much less mathematical
structures in the sense of Tegmarks Level 4!

In your Metaverse, let us call it the HAL-metaverse, I agree there is
no much point in discussing which interpretation is correct but it is
equally pointless to carry on any scientific arguments or experiments
given that complete pluralism reigns!!!

I am sure all those democrats running for office will be happy to
know they will all be elected in some world...

Tell me: If we live in all of them can we pick the cheapest one?
Than I would be interested...
