No, that isn't possible. Randomness is intrinsic, and not derivable from anything else. It could be based on something computable, and only appear random from our > perspective - presumbly some versions of many-worlds would fit the bill. No, many-worlds is a decided failure as far as randomness is concerned. You cannot get intrinsic randomness as exhibited by quantum phenomena from a deterministic theory such as many-worlds.

That is just a cheap let-out: "It could be something we haven't thought of yet. There are very good reason to think that intrinsic randomness cannot arise from a deterministic theory. You can get randomness from ignorance, as in classic statistical mechanics, but that is not intrinsic -- things are still deterministic if you have complete knowledge. Which is not the case in QM.
