Doing decision theory research might be a mistake in itself, if your goal is a positive Singularity and not advancing decision theory per se or solving interesting puzzles.

Isn't it sort of a moral imperative to familiarize oneself with the foundations of decision theory? It seems sort of important for understanding the foundations of epistemology, morality, ontology of agency, et cetera, which are things it'd be helpful to understand if you were trying to be morally justified. I guess this is to some extent what you meant by "philosophical interest"? -- Will Newsome on Luke's computer
