Leaving Google will let him speak his mind, without the self-censorship a Google executive must engage in. "I want to talk about AI safety issues without having to worry about how it interacts with Google's business," he says. "As long as I'm paid by Google, I can't do that." That doesn't mean Hinton is unhappy with Google by any means. "It may surprise you," he says.
