Facebook AI Chief Pushes the Technology's Limits

"This is the single most important problem to solve in AI today," says Yann LeCun, chief artificial intelligence scientist at Facebook Inc. It is a Manhattan Project-like effort that will go on for years, if not decades. At Facebook, Alphabet Inc.'s Google and other companies and universities around the world, scientists are working to create better AI that learns through self-supervision, teaching itself about the world the way people do. The immediate goal is broader AI that can perform multiple tasks, but that could one day lead to artificial general intelligence, or machines with humanlike thinking. A look at how innovation and technology are transforming the way we live, work and play.
