Google Turning Its Lucrative Web Search Over to AI Machines

When Google-parent Alphabet Inc. reported eye-popping earnings last week its executives couldn't stop talking up the company's investments in machine learning and artificial intelligence. For any other company that would be a wonky distraction from its core business. At Google, the two are intertwined. Artificial intelligence sits at the extreme end of machine learning, which sees people create software that can learn about the world. Google has been one of the biggest corporate sponsors of AI, and has invested heavily in it for videos, speech, translation and, recently, search.
