Sims are very cheap compared to space travel, and you need to know what you’re dealing with in quite a lot of detail before you fly because you want to have mapped the entire space of possible negotiations in an absolutely ridiculous level of detail.
Sims built for this purpose would still be a lot lower detail than reality, but of course that would be indistinguishable from inside if the sim is designed properly. Maybe most kinds of things despawn in the sim when you look away, for example. Only objects which produce an ongoing computation that has influence on the resulting civ would need modeling in detail. Which I suspect would include every human on earth, due to small world effects, the internet, sensitive dependence on initial conditions, etc. Imagine how time travel movies imply the tiniest change can amplify—one needs enough detail to have a good map of that level of thing. Compare weather simulation.
Someone poor in Ghana might die and change the mood of someone working for ai training in Ghana, which subtly affects how the unfriendly AI that goes to space and affects alien civs is produced, or something. Or perhaps there’s an uprising when they try to replace all human workers with robots. Modeling what you thought about now helps predict how good you’ll be at the danceoff in your local town which affects the posts produced as training data on the public internet. Oh, come to think of it, where are we posting, and on what topic? Perhaps they needed to model your life in enough detail to have tight estimates of your posts, because those posts affect what goes on online.
But most of the argument for continuing to model humans seems to me to be the sensitive dependence on initial conditions, because it means you need an unintuitively high level of modeling detail in order to estimate what von Neumann probe wave is produced.
Still cheap—even in base reality earth right now is only taking up a little more energy than its tiny silhouette against the sun’s energy output in all directions. A kardashev 2 civ would have no problem fuelling an optimized sim with a trillion trillion samples of possible aliens’ origin processes. Probably superintelligent kardashev 1 even finds it quite cheap, could be less then earth’s resources to do the entire sim including all parallel outcomes.
