This is also known as Simplicity Assumption: “If we randomly select the simulation of a civilization in the space of all possible simulations of that civilization that have ever been run, the likelihood of picking a given simulation is inversely correlated to the computational complexity of the simulation.”
In a nutshell, the amount of computation needed to perform simulations matters (if resources are somewhat finite in base reality, which is fair to imagine), and over the long term simple simulations will dominate the space of sims.
