I don't agree. The power of the All Universe Hypothesis (AUH) or of the
plenitude principle (arithmetical or not) is that the information
is typically 1-person point of view information.
So with AUH-like approach we have a 3-person O information theory
explaining why the embedded observer lives with many (1-person)
This is also one of the oldest argument in favour of the MWI appearing in
this list. If I remember correctly, it was put by Hal Finney.
