In a late night speech, Elon Musk told Tesla workers at the Shanghai Gigafactory that their hard work "warms my heart."
"I just want to let you know, it warms my heart," Musk said, tapping his chest before a fist pump.
Tesla workers then criticized Musk on Chinese social media, and some people even complained to his mom on Twitter.
Musk told CNBC he sleeps around six hours a night, and according to Jimmy Soni's book "The Founders," Musk was "perpetually sleep-deprived" at his first startup, Zip2.
