If we get to the point where we could start a simulation wouldn't self preservation be a reason not to start it. Because if we were in a simulation ourselves, turning on an other ones would raise the computing power needed for the simulation we live in and it might get shut down or at least take more time to compute?,(reply>), 2 things: 1) what if the original simulator allowed it because they are aware of their computing capabilities? 2) the first simulation that advanced enough to create a second level simulation might not know they are the first, and perhaps it necessarily will only manifest a second tier simulation once the CPU reached the necessary ba dwidth or computational power.
