Google debuts Assistant, a conversational AI helper

"We think of it as building each users its own individual Google," CEO Sundar Pichai said on the Google I/O stage today. He added that 20 percent of Google mobile searches today occur through voice searches. "We've started becoming truly conversational with our users," he said. As an example, Pichai offered up the idea of finding a movie to watch on a Friday night. Assistant will respond with the available titles and theater locations, as you'd expect.
