It hooks them up to a VR simulation of 1950’s america and they’re the abusive husband to a hot wife and two kids. Racism is alive and well and the USA and white people by extension run the world.
They can never leave, much like the matrix they’re locked into the simulation for life but it’s more humane than wholesale genocide because let’s face it, a lot of people in the USA deserve it.
A case can certainly be made for solipsism there too, yes, but I said deism specifically because of the techbro habit of believing that they come up with super original ideas because they can’t be bothered to check if someone already thought of that idea before, such as the idea of some creative force (the “simulation’s” programmer) creating the entire world as we know it (the “simulation”) and then setting it to run itself according to established physical laws (the “simulation’s” programming) and otherwise doesn’t intervene.
