stuart russell, welcome to hardtalk. hi.ave spent a career at the forefront of ideas on artificial intelligence. can you give me a working definition? very straightforwardly it means making machines intelligent. and what that means is traditionally making machines that act so as they achieve their objectives. that's more or less the same definition be applied to human intelligence. it's more or less the same definition we applied to any machine. i mean, we design a car to achieve the objective of travelling down the road in it, so is there something more about the intelligence that these machines that you work with and on are providing? yeah, so a car is designed to travel down the road but that objective is our objective. the car doesn't know that's what it's for. but these machines and in some sense, do. they have an explicit internal model of what their objective is and they can figure out how to achieve it. so there might have the goal of winning a game of chess and they can figure out how to do that and beat humans at i
