there is an arrow of computation, or rather, an actual present state, and time supervenes via perspective of computed observers

hmm: since you bring up perception, it the arrow of perceived time not always aligned to the psychological/computational one?

yes, perception is cognition, done via neural computation, which supervenes on pseudo continuum dynamics supervening on universe

I suppose I agree
Maroney argues that the computational arrow can run in either direction, but more likely to align
