Readers may find this new(ish) interpretation of quantum mechanics of interest (see also here). Basically, the authors suggest that QM should be understood in terms of many parallel worlds interacting with one another. On that note, I think it is worth pointing out some obvious similarities between their approach and the P2P Model that I proposed earlier here and here (for a brief overview, see also here). My model also understands QM in terms of many-interacting-worlds. One main difference--a difference that I believe may stand in favor of my model--is that whereas their model assumes a primitive, unexplained force pushing "nearby" worlds away from one another, my model explains the probabilistic nature of QM in terms of non-primitive, computational processes we already understand: the functional architecture of peer-to-peer computational networking. I also think the P2P Model explains philosophical phenomena (e.g. the mind-body problem, free will problem, and problems in the philosophy of time) that their model does not. Finally, my model has one important virtue that theirs does not: their model entails that all of the parallel worlds are equally real, including a vast variety of counter possible me's and you's in different dimensions. My model implies, to the contrary, that our actual, intersubjective "universe" is the superposition of worlds selected by sentient beings' consciousnesses in a peer-to-peer environment, whereas other possible universes are not actualized by conscious experience at all (and so, are merely possible universes that *could* have been experienced).
In any case, I'm glad to see the general, many-interacting-worlds approach gaining some traction!
