Looks like Tesla board of directors had enough, and decided to reign in... they have hired a bunch of smart recruits to help Elon before he burn himself out. https://www.tesla.com/fr_FR/blog/company-update
now he only has to kick the ambien before ending like Whitney Houston or Dolores O'Riordan - overdosing on the drug, stoned to death, drowning in a tube. 
Mostly agree with Orionblablam - I don't give a fuck about Tesla (the electric car revolution is now underway with or without Tesla) or Hyperloop, SpaceX is the highest priority
This. Real life ain't a fucking movie script. Also, lack of sleep or bad sleep can kill a person faster than a bullet, with mental health going off the rails on a crazy train (to you, Ozzy Osborne). World record for consecutive sleepness nights is merely nine days. Most people go nuts or dead with far less than that. Sleep a lot and prosper !
One among thousands of tortures invented by mankind along the ages, is sleep deprivation. It's easy, cheap, and extremely efficient. Put a guy in a small cage, then turn the blinding light on, 24 hours a day. Then add permanent 140 decibels noise, also 24 hours a day. Then wait for some days, and watch the result. Most humans end completely broken. Welcome to guantanamo, and welcome to Bachar jails.
