I tend to agree with this. I have used multiverse, like Deutsch, always in the sense of Everett Many-Worlds, with some nuances like “‘many consistent relative histories” à la Griffith and Omnes. But with quantum cosmology, the many-worlds can lead to “many universes” in a more concrete sense, which should not be confused with the interpretation of quantum mechanics itself, but of general relativity when quantised in a way or in another. > > That makes the multiple universes hidden variables.

Normally the Everett “many-worlds” do not interact at all (that would be non local indeed), but interfere statically, like mechanism predicts in arithmetic.
