An interesting talk relevant to what constitutes an "observer moment".

Even if the experience is smeared out over time
I think it is clear with mechanism that this is the case. Imagine an AI with a single
CPU. Here it is obvious that it's state extends through the dimension of time. With
the parallel processing of the brain it is less, but still much greater than a Planck time.
Even assuming signals at c the brain extends about a nano-second in time, 22 orders of
magnitude longer than the Planck time.
But doesn't this create problems for Bruno's argument, which assumes states are timeless,
instant like things in Platonia and that they have no overlap. Should we identify
observer moments with bundles of UD computations going thru the same state, but also with
extensions of those computations forward and backward over some number of states? But
they are not the same forward and backward. Or do we require that the "substitution
level" be pushed down to time slices short compared to a nano-second so that an observer
moment will be a whole set of states extending over a short time. In which case the
sequence of states will pick out a much smaller set of UD computations that went thru all
those states.

and has a complex
relationship to real world events it could still be the case that it
can be cut up arbitrarily.
Perhaps arbitrarily in the sense of distinct observer moments, but I don't think so
about time.
There is no way I can be sure the world was
not created a microsecond ago
Consider how many CPU cycles are required for the AI to become aware. Even if you think
it becomes conscious as soon as the first instruction is executed, the instruction takes
some amount of time to complete.
If it takes the brain 100 ms to compute a moment of awareness, then you can know you
were not created 1 microsecond ago.

and there is no way I can be sure there
isn't a million year gap between subjective seconds.
