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

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
