"Does Joe do anything at all if he rolls almost anything other than a 1, or does he just lie in bed? If the very large die is only rolled once, and all non-1s are very boring, then it is remarkable that we're here."
That's a very interesting point you raised, and I was thinking about this as well. If the universe only "exists once", and life is very unlikely but it still came to be, then it does seem remarkable.
However, this is based on the presumption that life is non-boring, and all other potential universes devoid of life are boring. This seems like a very subjective presumption. Clearly we are biased towards thinking that our own existence, or the similar existence of "life" is special. But a skeptic would claim that from a purely scientific perspective, there's no reason to believe that a universe without life is any more boring than our universe.
