You should read the papers associated with the simulation argument. There are, of course, loads of simulations you could run that don’t fit the confines of the argument. But if you don’t have a well-defined definition of simulation you can’t reasonably talk about the probably that you’re in one. Yes, you can simplify a great deal. You don’t need to simulate the moons of Jupiter before Galileo comes along. You can’t simplify an algorithm that is at its theoretically most efficient. That’s when you start running into the 1:1 problem. My argument is that the only way to avoid the 1:1 problem is to craft the simulation in such a way that it’s not an ancestor simulation as defined in the papers.
