Stuart Russell, Professor of Computer Science at University of California, Berkeley is one of the world's most respected experts on artificial intelligence. He explains what AI is, when we might expect machines to overtake humans in every activity, and why that means we need to rethink how we design and use algorithms, and ask the deepest questions about how we are as humans.
