I notice that, in topics that Eliezer did not explicitly cover in the sequences (and some that he did), LW has made zero progress in general. This is probably one of the reasons why.

<shameless self-promotion> My recent post explains how to get true beliefs in situations like the anthropic trilemma, which post begins with the words "speaking of problems I don't know how to solve." </shameless self-promotion>

However, there is a bit of a remaining problem, since I don't know how to model the wrong way of doing things (naive application of Bayes' rule to questionable interpretations). well enough to tell whether it's fixable or not, so although the problem is solved, it is not dissolved.
