I think the future of a digitized identity and is to have every individual registered to a unique cryptographic key that represents their "true identity." Under that sort of system, you have universality of record keeping that is linguistically neutral, but also no need to tie your identity to a "name" that isn't of your own choosing. What you "call yourself" and what your legal identity is do not need to be the same thing, just as when people call their friends by a nickname, they aren't referring to some other different person just because it's not the same as their "real name."

EDIT: Interesting discussion. Thanks for raising the question!
