Robot race cars and AI

What robots driving cars can tell us about artificial intelligence. Ed Butler speaks to Bryn Balcombe, chief strategy officer of the autonomous vehicle project Roborace. Gary Marcus, professor of psychology at New York University, explains why he thinks AI development is fundamentally limited. Yoshua Bengio, professor of computer science at the University of Montreal in Canada, gives a defence.
