The theory, which I probably misunderstand because I have a similar level of education to a macaque, states that because a simulated world would eventually develop to the point where it creates its own simulations, it’s then just a matter of probability that we are in a simulation. That is, if there’s one real world, and a zillion simulated ones, it’s more likely that we’re in a simulated world. That’s probably an oversimplification, but it’s the gist I got from listening to people talk about the theory.
But if the real world sets up a simulated world which more or less perfectly simulates itself, the processing required to create a mirror sim-within-a-sim would need at least twice that much power/resources, no? How could the infinitely recursive simulations even begin to be set up unless more and more hardware is constantly being added by the real meat people to its initial simulation? It would be like that cartoon (or was it a silent movie?) of a guy laying down train track struts while sitting on the cowcatcher of a moving train. Except in this case the train would be moving at close to the speed of light.
Doesn’t this fact alone disprove the entire hypothesis? If I set up a 1:1 simulation of our universe, then just sit back and watch, any attempts by my simulant people to create something that would exhaust all of my hardware would just… not work? Blue screen? Crash the system? Crunching the numbers of a 1:1 sim within a 1:1 sim would not be physically possible for a processor that can just about handle the first simulation. The simulation’s own simulated processors would still need to have their processing done by Meat World, you’re essentially just passing the CPU-buck backwards like it’s a rugby ball until it lands in the lap of the real world.
And this is just if the simulated people create ONE simulation. If 10 people in that one world decide to set up similar simulations simultaneously, the hardware for the entire sim reality would be toast overnight.
What am I not getting about this?
Cheers!
I think there are a few tricks that still make it possible. First, nothing says that you have to, or really that you can simulate a universe 1:1. When you think of it we already simulate millions of universes in video games, but they are dramatically simpler than our reality. So, our parent reality could be much more complex than our own.
Consequently, physics could be vastly different from one layer to another. Maybe in the real reality, entropy isn’t that significant and quasi-perpetual motion is possible, making energy super cheap. Maybe the limits in our universe like the speed of light and Planck constants are just hardware caps to prevent us from using too much compute.
