In the final episode of the series we'll look to the future to see how advancements in A.I. are increasingly blurring the distinction between what is human and what is machine. We'll look at the development of A.I. machines that combine with the human body to improve quality of life to those missing limbs, online chat bots which provide a social outlet for the lonely, and social robots that will one day become integrated into every aspect of daily life. But what might happen if these A.I. machines are programmed and directed by people with bad intentions? And what might happen when A.I can think for itself? What kind of future are we, and the machines that are becoming so much a part of our lives, creating for generations to come?
