I agree that MWI has nothing to do with consciousness
and 'human' observation (Everett describes the role of
the human brain and its limited memory capacity
and related problems of storage, though). 

It seems difficult to believe that MWI has nothing 
to do with measurements. No measurements no probabilities.
Even that experiment by Deutsch is based on certain
measurements (quantum mind reads the 'path'; observer
reads the photographic film; etc.).

But if you are saying that MWI describes what is 
happening everywhere in the universe, even in
the remote galaxies, even in the cosmic rays,
I agree.
