I am entirely unqualified to understand any of the multiverse theories beyond the explanations offered by analogies in popular science writing. But in short: No. I'm as hard a determinist as can be, to the point that I believe that any nondeterminism in quantum mechanics have deterministic explanations which are yet to be uncovered. I am also entirely unqualified to understand quantum theory.
