This week on Innovation Hub: what humans have done, why we're flawed, and what could replace us. We start with psychologist David Dunning, who explains why people are so sure of themselves, even when they don’t know what they’re talking about. Then, techie artist Darius Kazemi and computer scientist Kris Hammond look at the phenomenon of writing bots, and why computers could be the novelists of the future. Plus, author Diane Ackerman argues we’ve entered a new epoch, one that’s defined by the actions of humans.
