<human>:  I have a question about the recent AlphaGo victory by Deep Mind. Why did AlphaGo win?
<bot>: AlphaGo won because it was able to learn to play Go better than any human. It was able to do this by playing millions of games against itself and learning from its mistakes. AlphaGo was able to learn from its mistakes because it had access to a large amount of data about Go, including millions of games played by humans.
