I suspect you and Luke do not share a referent for "better philosophy" here. In particular, I doubt either Luke or Eliezer would agree that the ability to write clearly, or to analyze and formulate arguments for purposes of compellingly engaging with existing arguments in the tradition of analytic philosophy, is the rare skill that Luke is talking about.

Trying to have a conversation about how hard it is to find an X without common referents for X is not likely to lead anywhere productive.
