I have posted a number of times on this subject, and from experience,
I doubt I could convince you, even with a large reply. However, I
consider both the phenomna of "free will", and quantum mechanics to be
evidence of a random oracle at play. Note - I use the word _evidence_
advisedly - its not proof. It is possible to explain away these
phenomena by more straightforward mechanistic means, however, all
these explanations I've seen to date have been thin and unconvincing.

Incidently, whether UD* (output of the UD) is countable or uncountable
is irrelevant for whether observers see random values in their
histories or not, since at any point in time, their histories are
finite. However, the measure issue is important, as computable
histories have higher measure than ones that are only partially
computable. Therefore, if there are random oracles in nature, there
must be a good anthropic reason why they're there.
