Elon Musk is the co-founder and sits at the helm of Tesla, SpaceX, Neuralink, and The Boring Company. With a net worth of about $270 billion, he is currently the richest person in the world – and arguably one of the most influential, pushing for space travel, electric cars, and, among other things, artificial intelligence. He also altered the history of electronic payments in the late 90s and early 2000s when, after building and selling Zip2 to Compaq and then founding X.com, which became PayPal, he sold the nascent payment app to eBay in 2002. Today, he is such a powerful cryptocurrency trader that his tweets can affect pricing.
