Elon Musk stated that he needed the purchase of Twitter to "accelerate the creation of X, the app for everything." He did not provide more details. Perhaps Musk is alluding to the so-called "super apps" that are popular in China and other parts of Asia, the first being WeChat by Chinese tech giant Tencent. Such an app is usually a one-stop store for all your mobile needs, eliminating the need to have multiple apps for different functions.
