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?

i have a hard fucking time understanding what people want when they try to explain it to me, but i can code decently.  so i guess im only like ½ a programmer.
