      His Permutation City back in the day made me think about the nature consciousness like nothing else before.

      I have been using Permutation City in class. I also love his Ndoli universe stories: http://eidolon.net/?story=Closer

      Is there in fact some research that shines light on how processing speed affects (manifestation of) consciousness? https://xkcd.com/505/  (will check the stories).

      It should not make any difference per se, but you can only track what you can sample, and you can only integrate what you can fit into a signal loop. So if you are stuck with a given substrate, you don't want to be too slow or too fast.

      Would you consider a simulation to be integrated with the outside world, from the perspective of the simulated? Can consciousness be sustained if the state change takes orders of magnitude more time than e.g. the frequency our brains operate on?

      What happens if you freeze a simulation and resume it an hour later? As you said, there shouldn't be any difference from the "inside" point of view. But it certainly feels weird that moving rocks on a plane would create consciousness.

      But I think the flaw in that hypothesis is that it doesn't consider the movement of the rocks during placement as a state change in itself.

      The simulation running in our brain does not have somehow a window to the outside world. What we perceive as the outside world is the simulation. The relationship between mind and substrate is the same as between hardware and software.

      But the simulation in our brain still depends on raw data from the outside (i.e. the data drive the simulation to an extent). While a full universe simulation does not depend on the outside except in that it uses the outside substrate for the simulation itself.

      The particle universe that we run on is a small, controllable subset of the substrate universe. The perceivable universe is a small, modellable subset of the particle universe.

          Can't argue with that. But it still doesn't address that the simulation by the brain is causally dependent on the base universe, while a closed, full-universe simulation isn't (except in that it's constrained by it as to what it can simulate).
