    Can't say I'm familiar with the hazard function, but wouldn't human
    longevities of 2k to 7k extend doomsday dramatically into the future? I
    estimate that if typical human lives are from 2k to 7k then doomsday would
    be postponed approximately 25 to 90 times into the future. This could be a
    huge difference. For example if the supposed doomsday is scheduled for
    ~5,000 A.D. then now it is scheduled for sometime between ~125,000 A.D. to
    ~450,000 A.D.

    Certainly by 450,000 A.D. we could be very well advanced in Diaspora, which
    leads to the question of whether our spawned civilizations should be subject
    to our current doomsday equations or their own.

    I'm not following these doomsday threads closely, so forgive me if my
    thoughts have already been addressed.
