Interesting post. Unfortunately, I don't have enough time at present
to properly digest it or understand it.

I gather that your "rare events" are the ones of measure zero. In the
Schmidhuber ensemble, these events are never observed, and
consequently are ignored. Only finite length descriptions (ie the ones
with positive measure) are observable. Why do you think things like
the big bang, or inflation are of measure zero? It strikes me that
that these events are of rather low complexity, hence have fairly high
