One of the famous examples of AI technology that surprised everyone, even its makers, the Deepmind company (Which Musk invested in); is called
AlphaGo with its ability to learn and master board games such as chess, and the Chinese strategy board game ‘Go’. AlphaGo was the first software developed by Deepmind in 2015 and it won against the world champion Lee Sedol in 4 out of the 5 games. Later on, Deepmind came up with new software called
“Alpha-Zero” which was capable of defeating any opponent simply given the rules of the game. Alpha-zero won AlphaGO 100-0. Alpha-Zero learns the game by playing against itself many simulated rounds in seconds and within 30 hours of learning it was able to outperform AlphaGO on such scale. No one was able to predict this rate of improvement.
