Earlier quoted context omitted.
Right, that's interesting. Thanks. This is analogous to saying that we live in an Einsteinian simulation run from a Newtonian world, right?
I prefer to imagine we exist in a roughly newtonian program, but the computer executing it is a distributed system with finite local resources, so it doesn't all run in sync.
Do you know of anywhere where a model representing this is construed explicitly? It seems like the kind of thing that is harder than it seems, if you know what I mean :)
