Coming back to this comment, it seems to be another example of UDT giving a technically correct but incomplete answer.
Imagine you have a device that will tell you, tomorrow at 12am, whether you are in a simulation or in the base layer. (It turns out that all simulations are required by multiverse law to have such devices.) There’s probably not much you can do before 12am tomorrow that can cause important and far-reaching consequences. But fortunately you also have another device that you can hook up to the first. The second device generates moments of pleasure or pain for the user. More precisely, it gives you X pleasure/pain if you turn out to be in a sim, and Y pleasure/pain if you are in the base layer (presumably X and Y have different signs). Depending on X and Y, how do you decide whether to turn the second device on?
