Mark Zuckerberg and Elon Musk have shaped two very different sides of the modern technology world—social media and digital communication on one side, electric vehicles, space exploration and AI on the other. Zuckerberg built Facebook into Meta, while Musk developed a portfolio spanning Tesla, SpaceX and other technology ventures. Their careers, personal lives, education, family backgrounds, heights and fortunes make them two of the most closely followed entrepreneurs of their generation. Forbes’ current figures also show just how dramatically billionaire wealth can change with market valuations.
