Sure, but let's introduce a different notation

L(P,x) = the best way to solve P given computing power x

We know that

L(P,infinity) = AIXI or some variant

L(P, human brain power) = something with no resemblance to AIXI

It's really an open question what

L(P, nanotech supercomputer) = ???

Probably it will have aspects of AIXI and aspects of brain-ish architecture,
and some entirely different aspects as well.

The mixture of references to Chaitin's omega number and Tipler's Omega Point
is a bit confusing, no?
