        I'm not going to elaborate on this now because I have a ton of
work. Instead of doing a rush job, I will lay out the case against QS in
a form suitable for a FAQ, which this list sorely needs, when I get the
time. No doubt someone will write up a case in favor of it and people can
be referred to the FAQ. This will have to serve when I unsubscribe.
        Suffice it to say, though, that whether the number of branches is
finite or infinite makes little difference. The point is you lose measure
with a QS. Some people in the multiverse have more measure than others,
and measure is proportional to effective probability. If you deny this I
don't see how you can even explain why people descended from apes have
higher effective probability than those that form spontaneously.

        Yeah right. I wanted to see this crackpot proof only because
(unlike QS) it does directly touch on my interests, but unfortunately it
was unreadable. So what's the idea of the "proof"? In English.
