Instead of asking 'if' we should be asking 'what if', then we can make some predictions and find ways of testing them. We can also model the properties that we have into a computational model. One huge problem of this is the representation of time/change. If the machine can halt our world to produce the next game state then 'tick' there's no correspondence of our 'time' and outer world time so any properties involving time doesn't need to have any physical basis.
