Is metarationality about (really tearing open) the twelfth virtue?
It seems like it says "the map you have of map-making is not the territory of map-making", and gets into how to respond to it fluidly, with a necessarily nebulous strategy of applying the virtue of the Void.
(this is also why it always felt like metarationality seems to only provide comments where Eliezer would've just given you the code)
The parts that don't quite seem to follow is where meaning-making and epistemology collide. I can try to see it as a "all models are false, some models are u
becomes one model anyway, because you still have to choose which of the models are you going to use at a specific moment.
The architecture feels way different when you're not trying to have consistency though. Your rules for switching can themselves switch based on the current model, and the whole thing becomes way more dynamic.
