Elon Musk's X, formerly Twitter, is partnering with Visa to develop a payment service as part of its ambition to become an "everything app," akin to China's WeChat. This vision has been a long-standing interest for Musk, dating back to his early ventures in the late 1990s. However, the competitive landscape has intensified, with other tech giants expanding their offerings, while X faces challenges from rising hate speech and misinformation, potentially alienating users and advertisers. Additionally, U.S. regulators are scrutinizing Apple for allegedly stifling the emergence of super apps on its platform.
