Hi guys you don't know me and I prefer to stay anonymous.
I look at it backwards and get the very same result as Eliezer Y. What is total degeneracy? In practice, it is being total impervious to updating, regardless of the magnitude of the information seen (even infinity). That can only be achieved by unitary of nul probabilities as priors. Bayesian updating never takes you there (posteriors). And no updating can take place from that situation.
