'More and more people are buying media art'

In this edition of "Perspective" we look at the role of artificial intelligence in art. Our guests Christa Sommerer and Laurent Mignonneau are media artists participating in a new exhibit at the Grand Palais museum in Paris entitled "Artists & Robots". Their "Portrait on the Fly" piece invites spectators to challenge notions of self-identity, technology and art. They tell us more about their cutting-edge work.
