Netanyahu addressed the United Nations General Assembly in New York last week. Israel Prime Minister Benjamin Netanyahu warned the world is on the cusp of an artificial intelligence revolution that could launch nations into prosperous times or lead to all-out destruction fueled by devastating high-tech wars. "The AI revolution is progressing at lightning speed," Netanyahu said during his U.N. General Assembly speech last week. "It took centuries for humanity to adapt to the agricultural revolution. It took decades to adapt to the industrial revolution. We may have but a few years to adapt to the AI revolution."

The ancient strategy game of Go may have met its ultimate match. The brain-taxing board game is a little like an Eastern version of chess, except many times more complex. It has millions of devotees in China, Korea and Japan. Many of them tuned in today to watch an artificial intelligence computer built by Google's DeepMind beat the world champion, Lee Sedol, in the first of a five-game contest. Duels like these don't come often.
