Google's AlphaGo already beat us puny humans to become the best at the Chinese board game of Go. Now, it's done with humans altogether. DeepMind, the Alphabet subsidiary behind the artificial intelligence, just announced AlphaGo Zero. The latest iteration of the computer program is the most advanced yet, outperforming all previous versions. It's also different from its predecessors in one uniquely significant way: Whereas the older AlphaGos trained in Go from thousands of human amateur and professional games, Zero foregoes the need for human insight altogether. Like the unpopular kid in class, it will learn simply by playing alone, and against itself.
