I want to respond directly now...
It seems to me that winning the leverage lottery (by being at the dawn of an intergalactic civilization) is not like flipping a few hundred coins and getting a random bitstring that was not generated in that fashion, anywhere else in our Hubble volume. It is like flipping a few hundred coins and getting nothing but heads. The individual random bitstring is improbable, but it is not special, and getting some not-special bitstring through the coinflipping process is the expected outcome.
Therefore I think the analogy fails, and the proper conclusion is that models implying a "cosmic manifest destiny" for present-day Earthlings are wrong. How this relates to the whole Mugging/Muggle dialectic I do not know, I haven't had time to see what's really going on there. I am presently more interested in the practical consequences of this conclusion for our model of the universe, than I am in the epistemology.
Yeah, exactly. The issue is not so much the 10^-80 prior, as the 10^-80 prior on obtaining it randomly vs much much larger prior of obtaining it because, say, you can't visually discriminate between the coin sides.
