+(Although—one might speculate that "more classes to reduce collisions" could _be_ part of the historical explanation for grammatical gender, in conjunction with the fact that sex is binary and easy to observe. None of the other most salient features of a human can quite accomplish the same job: age is continuous rather than categorical; race is also largely continuous [(clinal)](https://en.wikipedia.org/wiki/Cline_(biology)) and historically didn't typically vary within a tribal/community context.)
+
+If you grew up speaking English, gendered pronouns feel "normal" while gendered [noun classes](https://en.wikipedia.org/wiki/Noun_class) in many other languages (where, _e.g._, in French, a dog, _le chien_, is "masculine", but potatoes, _la pommes de terre_, are "feminine") seem strange and unnecessary, but someone who grew up with neither would regard both as strange. If you spoke a language that didn't _already_ have gendered pronouns, you probably wouldn't be spontaneously eager to add them.
+
+All this seems correct as a critique of the existing English pronoun system! However, I argue that Yudkowsky's prescriptions for English speakers going forward goes badly wrong. First, Yudkowsky argues that it's bad for stances on complicated empirical issues to be baked into the language grammar itself: since people might disagree on who fits into the [empirical clusters](https://www.lesswrong.com/posts/WBw8dDkAWohFjWQSk/the-cluster-structure-of-thingspace) of "female" and "male", you don't want people to be forced to make a call on that just in order to be able to use a pronoun.
+
+Fair enough. Sounds like an argument for universal singular _they_ (and eating the cost of increased collisions where it's ambiguous which subject an instance of _they_ would refer to): if you don't think pronouns should convey sex-category information, then don't use pronouns that convey sex-category information! But then, in an unexplained leap, Yudkowsky proclaims:
+
+> So it seems to me that the simplest and best protocol is, "'He' refers to the set of people who have asked us to use 'he', with a default for those-who-haven't-asked that goes by gamete size" and to say that this just _is_ the normative definition. Because it is _logically_ rude, not just socially rude, to try to bake any other more complicated and controversial definition _into the very language protocol we are using to communicate_.
