Elon Musk Still MIA On Twitter As Tesla, SpaceX And SolarCity Problems Pile Up

Elon Musk may not be in hiding, but he is definitely missing in action on Twitter -- the social network he usually frequents to tease consumers and his critics of his next move or hint at upcoming updates and whatnot. The last that we heard of him was he was going to publish a post that would introduce the Autopilot 8.0 update and clearly explain how the controversial Autopilot system really works. And that was a week ago. On Sept. 1, the CEO of Tesla Motors took to Twitter to announce to his millions of followers that he was postponing his new blog post until the end of the weekend. He did this a day after sharing on the social network that he was writing the post and publishing it on Aug. 31.
