distributed in space and time avoid snapshots? You can still split
space-time into snapshots in the MWI (or "foliate" space-time in
relativity, I guess) in a manner that usefully explains extended processes
- they just extend across sequential snapshots / foliations. Digital
consciousness would presumably have a clock at some level, and steps, but
that might be far above the level of MWI snapshots, or it might be far
below it - space-time itself might be digital, which would automatically
allow higher level processes to be (in the sense required for comp).

Are you just saying that "observer moments" can't be identified with "MWI
snapshots" ?
