Even if there is a difference between a completely undetectable dragon and no dragon, does anybody care? I can see ethical implications MWI (multiverse theories in general, really) might have even if they’re not testable, analogous to the ethical implications of things not disappearing when they cross the cosmological horizon; but in the absence of any mention of practical reason, so much focus on interpretations seems unjustified.
