Thank you! I will chew on this overnight… My immediate reaction is “yes, this is familiar mainstream stuff, but I don’t think this is quite what the LW-sphere advocates, even taking into account community diversity”—but I need to think that through carefully before saying so!

Priors are an epistemological matter, not an ontological one. A utility function is ontological, I guess… but not at all what I have in mind. Rather: what is the right vocabulary for describing this sort of situation? Where “right” means not “ultimately correct,” but “helpful.”
-
I've been holding back from saying anything like the following, because it is indeed an obnoxious move, but I keep wondering what "helpful" grounds out to, for you, if anything - How do you know what's "helpful"? (And yes, it's epistemics again; feel free to throw ontology back)
-
I think all categories (outside math) are necessarily somewhat vague, and that this is not generally a problem. That includes “helpful.” There’s no general criteria. In particular domains, one can make cogent arguments about whether a particular thing is helpful or not.

To the guy in class who wants to know how to build an app that recognizes apples, so as to fix an ontology for counting them, we may legitimately say:. "That's going to take calculus and linear algebra, which requires learning 2 apples + 2 apples first."
