But that's not it.
Shares of Tesla stock slid Friday following Musk's appearance on the podcast and amid the departure of the company's chief accounting officer, Dave Morton, who left after just a month on the job.
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.
Musk stated that technology will be 'indistinguishable from reality, ' and, when prompted by Rogan on whether or not he entertained the idea of a 'simulation, ' appeared to confirm his sentiments.
At this point, you have either made your peace with it and want to let Tesla's genius just be himself; or you've been wondering how on earth (that giant, lightly crusted ball of lava) the stock price has defied the onslaught of missed targets, tantrums, the tent, Pedo-Gate, and the take-private-yeah?-nah fiasco.
"The level of public attention placed on the company, as well as the pace within the company, have exceeded my expectations", Morton said in a statement included in the filing. Musk's actions are making it "harder to support Tesla as a company", even as the fundamentals are improving, Munster said.
Even before Musk's surprise August 7 tweet that he had funding "secured" for a go-private deal, Tesla had been under scrutiny from investors, analysts and short-sellers as it works to hit production targets and slow its cash burn.

Elon's consumption of the drug might have gone against Tesla company policy.
"Totally legal", Rogan responded, handing Musk the joint.
Guardado told the outlet that her use of doctor-recommended drops could make her test positive for the drug, a condition she says she told the company about prior to her termination. His interview with Joe Rogan has become notorious because during it he smoked pot on camera - a single puff, taken in California where recreational cannabis use is legal under state law.
Tesla has long struggled with high turnover involving its senior executives, and its finance team in particular has gone through a period of significant tumult.
The 47-year-old sat down with Rogan for an expansive two-and-a-half-hour interview, covering topics from AI to flame-throwers to social media, before the host kicked back and started to smoke up.
There has been periodic talk of installing a No. 2 under Musk or a chief operating officer, as is the case at SpaceX, his private rocket company.
"It's time for Tesla and Elon Musk to grow up", Michelle Krebs, executive analyst at Autotrader, said Friday.
Tesla reached that level in late June, but did so by working around the clock and hastily adding a third assembly line in a huge tent outside its factory in Fremont, California - a measure that auto-manufacturing experts had never seen before.
