Honestly, I think Tesla would be better off if Musk were to go away - at this point. Musk really is the perennial entrepreneur. He's a great idea man, and he can get a company built and make that idea come to life. But he can't run a business.
I think Musk has overstayed his welcome at Tesla. He did it - he took EV's from the niche that hardly anybody paid attention to and made them mainstream. Bravo! I never would have thought he could have done it - but he did. Now it's becoming clear it's time for him to step away and tackle another problem. Otherwise he risks interfering with his own success.
