Possibility of an Illiterate Programer?

/prog/, is it possible for a person to know how to code and program computers before knowing how to read and write in English (or any other natural language)? Is there an example of, maybe, a savant with extraordinary talents in the field, but is, otherwise, social inept?

>>4 Yeah, GTFO of this thread. I'm seriously asking /prog/ if there is a brillant savant, out there somewhere, whose gift is programming computers or deep mathematical logic.
