There are other, more interesting and important ways to use that compute capacity. Nobody sane, human or alien, is going to waste it on running a crapton of simulations.
Counterpoint: speedrunning and things like ‘Twitch plays’, which are some of the most popular streaming genres in existence, and exist largely because they are unimportant. A TAS speedrunner may well run millions or billions of simulations simply to try to shave off 1s from the record. (An example I like to cite uses 6 CPU-years to bruteforce NES Arkanoid to achieve nearly optimal play. Unfortunately, he doesn’t provide the wallclock equivalent, but I strongly suspect that this project alone simulates more minutes of NES Arkanoid than it was ever played by humans. If not, then I’m quite sure at this point that NES Mario has been played in silico OOMs more than by humans. Plenty of projects like ‘My First NEAT project’ will do a few years or centuries of NES Mario.)
