Imagine a case of existential risk, in which humanity needs to collectively make a gamble.
We prove that at least one of 16 possible choices guarantees survival, but we don't know which one.
Question: can we acquire a quantum random number that is guaranteed to be independent from anything else?
I.e. such that the whole world is provably guaranteed to enter quantum superposition of all possible outcomes, and we provably survive in 1/16th of the worlds?
Are you assuming a non-MWI universe? Doesn't every source of randomness just imply different branches in proportion to their amplitude?
I'm assuming MWI, but noticing that NOT every source of "randomness" implies different branches.
Some things may, or may not, be interconnected in ways we don't see, and can't detect. (E.g. it's been shown that humans can learn to flip coins predictably etc.)
My point is to provably, with as high confidence as we require split the world into different branches, as opposed to having a pretty good chance but we don't know exactly how good of creating different branches.
