It was one of the few times I witnessed Musk being unsure of himself. Over the next five months, through the close of the deal in October, he would at times express great excitement about the chance to turn Twitter into an “everything app,” featuring financial services and great content, while helping to save democracy in the process. At other times, he would get coldly angry, threaten to sue the Twitter board and management, and insist that he wanted to call the whole deal off.
