Here is what lies ahead for Musk, the self-proclaimed "Chief Twit", according to current and former Twitter employees, analysts and investors who considered funding the deal.
Musk's biggest bet borrows from China's greatest hits of the 2010s. "Buying Twitter is an accelerant to creating X, the everything app," Musk tweeted earlier this month.
The idea of an everything app, also referred to as a super app, originated in Asia with companies like WeChat, which lets users not only send messages but also make payments, shop online or hail a taxi. The all-in-one service appealed to users who had fewer choices in a region where Google, Facebook and others were blocked.
