It seems like a mess of tautologies and thought experiments
My own view is that this is precisely correct and exactly why anthropics is interesting, we really should have a good, clear approach to it and the fact we don't suggests there is still work to be done.
r/Fitness does a weekly "Moronic Monday", a judgment-free thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. I thought this seemed like a useful thing to have here - after all, the concepts discussed on LessWrong are probably at least a little harder to grasp than those of weightlifting. Plus, I have a few stupid questions of my own, so it doesn't seem unreasonable that other people might as well.
