Elon Musk is constantly making headlines about his radical political and social opinions, his thirst for innovation, and his drive towards successful businesses.

The letter X has had a significance in his life from the beginning. He wants to build it into an all-encompassing app. Like in China, where We Chat is used by more than a billion people as an all-in-one social media, instant messaging and mobile payment app.

Musk said that his attempt to buy Twitter was a part of accelerating the process of creating X, ‘the everything app’, and “something that would be very useful to the world.”
