Tesla has long touted the importance of keeping Musk at the helm of the company, saying in annual SEC filings that Tesla is "highly dependent on the services of Elon Musk, our Chief Executive Officer and largest stockholder." Anderson agreed that Musk is essential to Tesla, but suggested a less formal role to Barron's like "chief ideologue."
