My Take
Marc Andreessen sits at the root of the web we take for granted. Co-authoring Mosaic, the browser that first put images beside text, then founding Netscape, he literally shaped how the internet looks. His pivot from engineer to venture capitalist at Andreessen Horowitz is a rare second act that arguably carries even more influence than the first. I respect the conviction behind his relentless techno-optimism, even when I want to argue with it. From small-town Iowa to the Internet Hall of Fame, he is one of the few people who genuinely rewired daily life for billions.
