                        This comes back to my original question: since
            all possible
                    programs
                        are run by the dovetailer, how do we ensure that
            conscious
                    beings
                        see an ordered and predictable world. Only a set
            of measure zero
                        among all possible programs would give that result.

                    Yes, it seems to me, we should see white noise, but
            maybe a
                    selection attribute must be in play... like an
            anthropic argument.


                Anthropic arguments are not going to work with
            computationalism
                because there is no basis on which you can assume underlying
                deterministic physical laws.

            It seems to me it works relatively.... consciousness like
            ours can only experiment worls ordered like ours... even if
            almost all dreams/worlds produced by mathematics are not
            like that and do not allow of consciousness like ours, as
            you can only experience worlds like ours, it's no magic that
            you do... like with Quantum Immortality, you cannot
            experience being dead, so no wonder you find yourself alive,
            even if in almost all worlds you're dead (or not existing at
            all).

        But we do not need the degree of order that we observe. We could
        survive perfectly well with a reasonable number of miracles --
        laws that don't quite work always. And there are vastly more
        possible worlds of that sort than those that are strictly
        deterministic. The measure problem gets you every time.

    Possibly, but how do you prove that's more likely to be experienced
    than regularity? Do miracles require more or less bits to specify
    than "same old, same old" ? Could the nature of consciousness be
    such that the most likely continuer of a given observer moment is
    the one that has the least available difference from the previous
    one (in some sense - is it possible to do some maths on this? (must
    dig out TON....again....))


It would take a vast amount of coding "by hand" to create a universe filling in details of miracles occurring at multiple arbitrary points, as opposed to an orderly universe with a few laws and initial conditions.

Not necessarily. Just insert a few (pseudo-)random numbers at strategic points! But, on the other hand, the UD runs all possible programs, so what does it matter if a few are a bit complicated. :-)
