    I think that this can be said, and is true, whether we discuss the
    physics of it or the more important aspects.

    Our default supposition IMO should be that the quality is objective.
    We are naturally evolved creatures, and taking as often as we can
    the "bird's eye view", the human beings' values of quality have a
    number of characteristics that are increasing: the quality of their
    information firstly relates to how much they know about their
    universe. A completely objective analysis would reveal that the
    average human nervous system now possess far more accurate maps of
    its surroundings and its place in space than ever before.

    The ideas that I had always understood were that the "sum total of energy"
    of the universe being zero, and the "sum total of information" in the
    universe was zero. In other words, information was never lost, except
    in the possibly troubling case of black holes.

    Then, later, when one relinquishes the idea of wave collapse, one
    allows that the Schroedering equation is time reversible. So, I
    had also gathered that from the point of view of QM or MWI, there
    was no information increase in the universe. But perhaps the
    Level Two Linde proliferation of new bubbles changes that? Well,
    one argument that it doesn't is that you always have exactly
    aleph-null bubbles, period.

    I have to leave alone your other interesting points for now.
