Mark Zuckerberg

American entrepreneur — co-founder and CEO of Meta (formerly Facebook) — who built the world's most-used social media platform from a Harvard dorm room — controls Meta through supervoting shares — and has pivoted Meta toward AI and the metaverse.

Creates the social graph as the core infrastructure of online social life — Zuckerberg's insight (that mapping real-world social connections, not anonymous internet connections, was the product) produced the dominant social network through its ability to map pre-existing offline relationships.
