  • In March 2016, DeepMind’s AlphaGo defeated world‑class Go player Lee Sedol, marking the first time a machine outperformed a top human in a complex board game. The victory, achieved through deep neural networks and self‑play reinforcement learning, accelerated AI research and reshaped perceptions of human versus machine competition. While the loss prompted some players, like Kasparov, to advocate human‑AI collaboration and new tournament formats, the popularity of Go and chess has actually risen. Today, mobile platforms and online communities host hybrid competitions, blending human creativity with AI’s computational power.
