What is your definition of philosophy for this article?
Why is it a failing of a highly intelligent mind that it can't "do philosophy"?
Why would a Bayesian EU maximizer necessarily be unable to tell that a computable prior is wrong?
When is Bayesian updating the wrong thing to do?
What should I have learned from your link to Updateless Decision Theory that causes me to suspect that EU maximizing with Bayesian updating on a universal prior is wrong?
Doesn't rationality require identification of one's goals, therefore inheriting the full complexity of value of oneself?
What would count as an example of a metaphilosophical insight?

From what I can glean from the UDT descriptions it seems that UDT defines 'updating' to include things that I would prefer to describe as 'naive updating', 'updating wrong' or 'updating the wrong thing'.

Pray tell, what is the right thing to update?
