Alphabet Inc. has been one of the world’s biggest spenders on artificial intelligence. The advancements have even surprised company co-founder Sergey Brin. Speaking at the World Economic Forum in Davos, Brin said that when he was in charge of Alphabet’s research group he didn’t pay much attention to a team working on artificial intelligence. Now the technology, operated by a division of the company called Google Brain, touches nearly every piece of its business, including translation, photography and advertising.
