-However, if you were going to reform Spanish (or some other language with the second-person formality distinction), you would probably abolish the distinction altogether, and just settle on one second-person singular pronoun. Indeed, that's what happened in English historically—the formal _you_ took over as the universal second-person pronoun, and the informal singular _thou_/_thee_/_thine_ has vanished from common usage. (People still recognize it as a second-person pronoun when encountered in old poetry—"The truth shall be thy warrant", _&c._—but most probably aren't aware of the formality distinction.) You wouldn't keep both forms, but circularly redefine them as referring only to the referent's preferred choice of address (?!). Similarly, when second-wave feminists objected to the convention of _Miss_ or _Mrs._ forcing speakers to identify a woman's marital status, the response was [to popularize the marriage-agnostic alternative _Ms._](https://en.wikipedia.org/wiki/Ms.#Historical_development_and_revival_of_the_term), not to circularly redefine _Miss_ and _Mrs._

+Or consider how previous generations of public intellectuals considered this exact problem. In 1983, Douglas R. Hofstadter also expressed disapproval of _she_ and _he_ as a matter of language design, and to illustrate the point about how alien and unnecessary gendered language would seem if you weren't already used to them, wrote a satirical piece, ["A Person Paper on Purity in Language"](https://www.cs.virginia.edu/~evans/cs655/readings/purity.html), in the persona of a conservative author in a society with race-based (!) language conventions, including the pronouns whe/wis for whites and ble/bler for blacks. In neither the piece itself (during which Hofstadter's alter-ego brings up and rejects a couple of reform suggestions from the liberals of whis Society, including singular _they_), nor the Post-Scriptum in its subsequent [anthologization](https://en.wikipedia.org/wiki/Metamagical_Themas), does Hofstadter entertain the idea of redefining _he_ and _she_ (or _whe_ and _ble_) to refer to the subject's pronoun preference. It's worth asking: why not? If it's so clear to Yudkowsky in 2021 that self-identification is the "simplest and best protocol" to repair the objective flaw in English's design, why didn't that simplest and best solution occur to Hofstadter in 1983?
