    If that's the case, then mustn't the whole DA fail because it depends
    on hypothetical entities?

    In any case, Eliezer's thought experiment is a great illustration of
    my original objection which started this thread. So far in time, on
    this planet, the DA has been wrong every single time it's been
    invoked. So, shouldn't that cast some doubt on the DA? And shouldn't
    that *concrete evidence* take precedence over the rather arbitrary
    assumptions about random sampling and distribution of populations that
    the DA depends on?
