Albert-László Barabási

Barabási is the mathematician of the rich-get-richer. When he and his research group set out in the late 1990s to map the World Wide Web, they expected a democratic, bell-curve structure; what they found was a universe dominated by a handful of colossal hubs and a long tail of near-invisible periphery. That discovery of scale-free networks and the mechanism behind them—preferential attachment, the process by which new connections flow preferentially to nodes already well-connected—revealed that inequality in complex systems is not an accident but a mathematical law, as reliable as gravity. His subsequent work on the fitness model showed how high-quality newcomers could nonetheless rise against incumbents, and his 2025 research on human-AI coevolution traced how the feedback loops between people and algorithmic systems are reshaping not only what we create but who we are becoming. For the [YOU] on AI cycle, Barabási is the scientist who explains—with the precision of a power-law exponent—why the democratization of creative capability does not automatically
