Elon Musk is undoubtedly an outstanding entrepreneur. In an interview, the host asked him: “What connection is there between your businesses—payments, electric vehicles, and space travel?” He replied thoughtfully that, when he was in college, he already believed that the three biggest opportunities for humanity were the internet, interstellar travel, and clean energy.

Could it be that Musk was so farsighted even back in college?
From PayPal > Tesla > SpaceX, after acquiring Twitter/X, he will probably go back to payments first—starting with x.com. The fact that x.com was merged with PayPal has always been a lingering regret for Musk. He kept the domain all along until after he acquired Twitter, and then brought it back to use.
