For one thing, we already have strong evidence rationality is a useful idea: it’s called science & technology.
Cassandra’s world: Mythical predictions seem to be unconditional whether Bayesian predictions are conditional on your own actions and thus can be acted upon.
Buddha’s world: Well, understanding your own values and understanding how to maximize them are two tasks none of which is redundant. I think rationality is useful in understanding your own values as well, for example by analyzing them through evolutionary psychology or cognitive neuroscience. Moreover, empirically understanding of our own values also improves when learning epistemic facts and analyzing hypothetical scenarios. Without rationality it is difficult to create sufficiently precise language for formulating the values.
