    I started to respond to Robin's comments -- but they may be impacted
    by multiple source comments over the last 24 hours -- so they may
    be better dealt with in a formal paper of some type -- that is
    going to need to wait until I get through "Where Is Everybody?"
    to see if it adds anything useful to the conversation.

    But the question of "Why replicate?" (and how to best do so)
    is interesting (and perhaps relevant to the F.P.).

    It would appear that one might have:
    (a) random evolution (e.g. order arising from chaos -- the Earth to date);
    (b) other directed evolution (e.g. we are all running in a simulation);
    (c) self-directed evolution (e.g. we drive ourselves in some
        direction -- say determined by something like the extropian
        principles).

    My position with regard to the F.P. seems to be based on (c)
    and the idea that many, if not all, logical, intelligent,
    technological civilizations reach the same conclusion with
    regard to the best direction(s) in which to drive ones
    own self-evolution.

    Can anyone offer reasons as to why (a) or (b) trump (c)?
    (And we are talking variety of time scales ranging anywhere
    from thousands to trillions of years).

    Robert
