This is an important theorem. There is no perfect decision theory, especially against equal-or-better opponents. I tend to frame it as “the better predictor wins”. Almost all such adversarial/fixed-sum cases are about power, not fairness or static strategy/mechanism.
We (humans, including very smart theorists) REALLY want to frame it as clever ways to get outcomes that fit our intuitions. But it’s still all about “who goes first (in the logical/credible-committment sense)”.
