Do simulators allow the use of simulation technology by the people within the decision-making simulation? If they do, the computational costs will be enormous, and a huge chain of simulations within simulations threatens. If they don’t, then the simulated reality will be quite unlike the unsimulated reality (where use of simulation technology will be ubiquitous). Either way, when a given simulation technology becomes widespread among a group of people, it thereby becomes less useful for purposes of predicting what those people will do.
