I think relying on the sum/integral over all possible programs as the FINAL
explanation would lead to avoiding the questions about details of the
criteria. We are safe because we are included in the overall sum.  True, for
the general purpose of explaining our existence, we don't know the details
of the criteria. But if we are deeply involved in modeling specific
fundamental phenomena, or are just extremely curious, we are led to pursue
the details of the criteria, instead of staying satisfied with the top-down
result. True, we will never succeed in finding out the actual program, but
we can speculate about it, and could try to approach it asymptotically (that
is what I meant by narrowing down the infinite subset of options) from a
bottom-up approach. I feel that is what science is all about.
