You are optimist :)

According to Nick Bostrom who introduced the term, "observer-moments
are pieces of subjective time"
(http://www.escribe.com/science/theory/m1220.html).

I think that some people here associate them to computational states. I
do that but it is not a 1-1 correspondence. You can associate an
"observer-moment" to some (sufficiently rich) computational state, but
to each "observer-moment" you can only associate an infinity of
computational states. All regularly accessed by the Universal
Dovetailer through many computations/histories. Now those computational
state are relative state. They make sense only with respect to a most
probable history/universal-machine/maximal consistent extension ... I
don't think the ASSA people would agree, and I would appreciate they
make more precise their notion of "observer moment".

I hope so ;), we will see.
