Something strange happened in the world of artificial intelligence (AI) on Wednesday. Facebook CEO Mark Zuckerberg posted on his Facebook profile that his company has created an AI system that is "getting close" to beating the best humans at Chinese board game Go. Hours later, DeepMind -- a startup based in London that was bought by Google for 400 million in 2014 -- said it had already developed an AI named AlphaGo that had just beaten the best Go player in Europe. DeepMind's breakthrough was splashed across the front cover of science journal Nature yesterday evening and covered by over 200 media titles. "This is the first time that a computer Go program has defeated a human professional player, without handicap, in the full game of Go - a feat that was previously believed to be at least a decade away," explained the DeepMind research paper -- Mastering the game of Go with deep neural networks and tree search.
