Kevin Leyton-Brown is an optimist about artificial intelligence (AI), but he doesn’t present himself as such. On the contrary, the professor of computer science and director of UBC’s Centre for AI Decision-making and Action (CAIDA) assumes a position that is deeply philosophical. When talking about the potential of AI as a force for good, he says, “You have to have humility. You have to avoid the colonialist impulse to say this is going to make life better.”
