Your beef is not just with me; it is with Bruno De Finetti and Frank P.
Ramsey and their modern followers in the subjectivist school of
probability theory, most of whom call themselves subjective bayesians.
This is true, but, subjective Bayesianism does not give you any
suggestion as to what prior distribution to use in place of the
maximum-entropy prior.
It just says that you can use any prior you want so long as you use it
consistently...
So, for AGI purposes, the subjective Bayesian approach is not enough...
