| Contributions | Musk's work joined software entrepreneurship with heavy engineering. The proceeds from Zip2 and PayPal funded SpaceX, where reusable first stages turned rockets from disposable vehicles into repeatable ones, and Tesla, where batteries, software and charging infrastructure were developed as one system. His later ventures apply the same pattern to other fields: Neuralink to brain-computer interfaces, The Boring Company to tunnelling, and xAI to artificial intelligence. The common thread is taking a capital-intensive industry, redesigning its economics around reuse and vertical integration, and setting a long-term goal — cheaper access to space, sustainable transport — that the company is organised around. | Bezos changed how people buy things. Amazon showed that a retailer could hold almost no shops and still offer more choice than any shop, and its systems for ordering, delivery and reviews became the pattern for e-commerce worldwide. Amazon Web Services turned the computing infrastructure Amazon had built for itself into a service other companies could rent, making cloud computing a standard part of running a business. With Blue Origin he helped open spaceflight to private companies, arguing that reusable rockets would lower its cost. His purchase of The Washington Post in 2013 kept a major American newspaper under private ownership at a time when newspapers were losing money. |
