Perhaps you're not familiar with the history of this mailing list, but
Juergen Schmidhuber is one of the first authors to explicitly state the
idea that all possible universes exist in a published scientific paper,
and that paper is cited in the public invitation to this mailing list. I
have to say it's very inappropriate to publicly "plonk" him when it seems
to be you that doesn't understand the issue at hand. 

I agree with Juergen that AP does not predict anything by itself. You need
at least a probability distribution or measure of some sort in addition to
AP. There has been extensive discussion on this list over exactly what
measure should be used, and what the measure is over.

Have you read Juergen's paper "A Computer Scientist's View of Life, the
Universe, and Everything"? If not please do so before making any more
posts. It's at http://www.idsia.ch/~juergen/everything/html.html.
