Google CEO Sundar Pichai: Artificial intelligence more 'profound than electricity or fire'

"AI is probably the most important thing humanity has ever worked on. I think of it as something more profound than electricity or fire." That's a bold claim for anyone to make, but even more significant given the speaker: Google (GOOGL) boss Sundar Pichai. He was giving his take on the frontier technology in a speech at the World Economic Forum in Davos, Switzerland, on Wednesday. Pichai, Google CEO since 2015, has pushed his firm deeper into developing artificial intelligence under parent company Alphabet (GOOGL).
