Musk, 47, sipped whiskey during a more than 2 1/2-hour podcast interview with comedian Joe Rogan late Thursday that touched on topics from flame throwers and artificial intelligence to the end of the universe. They did the kind of things you'd expect people to do on Joe Rogan's podcast: they talked about the cosmos, the rise of AI, samurai swords, and drugs.
Tesla Inc shares fell almost nine percent on Friday as the resignation of its chief accounting officer after just a month at work spooked investors amid another social media storm around billionaire chief executive Elon Musk.
In August, Musk told the New York Times he was exhausted from too much work and difficulty sleeping in an interview that sharpened questions about his mental stability.
Tesla's chief accounting officer gave notice he's resigning one month into the job, citing the level of scrutiny on the electric-car maker. The Palo Alto, California-based company faces concerns about its limited cash balance, maturing debt and struggle to steadily build high volumes of the Model 3 sedan, the first electric vehicle that Musk has attempted to mass-manufacture.
Musk, seemingly referencing former president Bill Clinton, went to Twitter to say that to say, "remember, I did not inhale".
Accounting officer Dave Morton's resignation was announced in an official filing with United States regulator the Securities and Exchange Commission.
Mr Morton, who joined Tesla on 6 August, resigned on 4 September.
The negative press Musk has received since his tweet last month about potentially taking the company private likely has some investors concerned about the executive's responsibilities.
In a new blog post, Musk announced a number of top management changes after discussing with the Tesla board of directors and executive staff. "As a result, this caused me to reconsider my future", Morton was quoted as saying in a company filing.
The hiring of the accounting chief, Dave Morton, had been announced days before Musk abruptly took to Twitter last month and declared that he was planning to take Tesla private and had "funding secured".
Morton clarified that he believes strongly in Tesla, its mission, and its future prospects, adding that he has no disagreements with Tesla's leadership or its financial reporting.
But a large portion of that gravitational potential energy could be recaptured and harvested on the descent, Musk said. Although he abandoned the idea less than three weeks later, he remained under investigation by the SEC.
