  • Arianna Huffington told Elon Musk to get some more sleep.
  • But the Tesla CEO snapped back in a tweet sent at 2:30 a.m.
  • Musk said he had no choice but to work long hours because the alternative was potentially catastrophic for Tesla.
  • It follows his brutally honest interview with The New York Times in which he opened up about his “excruciating” 2018 work schedule.

After another dramatic week for Elon Musk, in which he bared his soul in a brutally honest interview with The New York Times, his acquaintance Arianna Huffington took the time to offer the Tesla CEO some advice.

Musk complained of working as long as 120-hour weeks as part of an “excruciating” 2018 work schedule, which he suggested was taking its toll on his physical and mental well-being.

Huffington’s advice was simple: Get some more sleep. In an open letter on her Thrive Global website, Huffington explained that humans, just like Musk’s electric cars, needed time to recharge.

“Tesla is revolutionary because it’s all about how we can most efficiently use energy, which holds the potential to change the world,” she wrote, adding: “You’re demonstrating a wildly outdated, anti-scientific and horribly inefficient way of using human energy.”

Huffington tweeted the post on Friday. And, perhaps in a perfect illustration of her point, Musk responded at 2:30 a.m. on Sunday, shortly after clocking off from a shift at the Tesla factory.

“Ford & Tesla are the only 2 American car companies to avoid bankruptcy,” he tweeted. “I just got home from the factory. You think this is an option. It is not.”

Musk told The Times that he often faced a choice of insomnia or taking Ambien, a sedative used as a temporary treatment to sleep problems. His late-night Twitter binges have worried some Tesla board members, The Times said.

The company is said to be actively searching for a deputy for Musk to alleviate his workload. Musk said Tesla approached Facebook’s chief operating officer, Sheryl Sandberg, but she presumably declined given that she is still at Facebook.
