Musk's worst enemy
Is himself. There is no doubting he is a visionary and he has pushed his businesses further than anyone else would dare.
At the same time even a visionary needs a filter to stop the stupid from bubbling up to the top. On top of that he is clearly overworking himself and the pressure / ambien means the stupid has joined forces with impetuous and nasty. It's just one bad news story after another and the stock has taken a massive hit.
It's probably why Tesla announced a bunch of promotions on Friday. Hopefully it's the company stepping up (or intervening) to relieve Musk of some of his duties and hopefully impose some normality on their business. Musk is fine as a figure head and a visonary but he needs to step back and allow some of his subordinates to do what they're there to do.
