Artificial intelligence isn't the scary future. It's the amazing present.

The year 2017 arrives and we humans are still in charge. The machines haven't taken over yet, but they are gaining on us. Google's DeepMind AlphaGo computer program recently beat the world champ at Go, a complex board game, while Japanese researchers plan to build the world's fastest supercomputer for use on artificial intelligence projects. It will do 130 quadrillion calculations per second, which is, um, really, really fast. She can explain it better than we can.
