To show a problem with SIA, assume there is one copy of you, that we flip a coin, and, if comes out tails, we will immediately duplicate you (putting the duplicate in a separate room). If it comes out heads, we will wait a minute before duplicating you.
We could make it simpler: flip a coin and duplicate you in a minute if it comes up heads. A.k.a. sleeping beauty. We already know that SIA forces you to update when you go through an anthropic “split” (like waking up in sleeping beauty), not just when you learn something.
