Elon Musk has announced that he will be replaced as CEO of Twitter in six weeks, with the new CEO believed to be Linda Yaccarino, chairman of global advertising and partnerships at NBC. Musk, who will become executive chair and CTO, wants to focus on his other ventures while allowing someone else to run Twitter. However, Moritz Appels warns that Musk's presence and influence may limit the new CEO's ability to implement change and exert authority.
