Tesla CEO Elon Musk has officially given himself a new title.
A document filed with the SEC shows that as of Monday, Elon Musk officially has the title of "Technoking" at Tesla.
The same filing shows that Tesla chief financial officer Zach Kirkhorn has also been given the title of "Master of Coin." This is an apparent reference to the television series "Game of Thrones" — or the book series it was based on, "A Song of Ice and Fire" — in which the position of royal treasurer was called "Master of Coin."
