Artificial intelligence (AI) took a giant leap in the public’s eye when a machine beat the grand master of the Asian strategy game Go, in four out of five games. The victorious machine, AlphaGo, made use of more than the basic AI associated with Watson, the software and computer from IBM that won Jeopardy. The kind of software needed to defeat the Go grand master can teach and write its own programs based on an ongoing stream of new data, something called deep learning (DL). In addition, AI now includes another kind of capability called machine learning (ML), in which machines with sophisticated software learn and digest new data, bringing new capabilities to the fore. Large digital tech companies, such as Google, Facebook, Baidu, Microsoft and IBM, have shifted their research focus to cognitive computing, which includes all AI approaches. Money is flowing and products are emerging. Some worry about the potential effects of current cutting-edge AI, but the industry has decided to move forward.
