Technoking Of Tesla Sued For Tweeting Sadly, nothing about the above headline is satirical or even exaggerated. Author: Sadly, nothing about the above headline is satirical or even exaggerated. Effective as of March 15, 2021, the titles of Elon Musk and Zach Kirkhorn have changed to Technoking of Tesla and Master of Coin, respectively. Elon and Zach will also maintain their respective positions as Chief Executive Officer and Chief Financial Officer. Separately, Tesla disclosed Monday that Jerome Guillen, president of automotive, has transitioned to the role of President, Tesla Heavy Trucking. “Further unchecked tweeting by Musk” could “have severe ramifications on the company’s ability to secure financing,” and it “drives out the very voices in the company meant to stand up to him and protect” investors, the complaint says.
