The Computer Scientist Who Mastered Go

French scientist Rémi Coulom built Crazy Stone, a computer program that shocked the world by defeating professional human Go players years ahead of expert predictions.

For decades, experts believed computers would never beat humans at the complex board game Go because it requires intuition rather than brute force. Coulom changed everything by developing algorithms that allowed machines to learn from their mistakes. His work served as a critical stepping stone for the artificial intelligence breakthroughs that eventually mastered the game completely. It is a perfect example of how a singular focus can break long-standing barriers in technology.
