    The Battle for the Soul of Artificial Intelligence

    The Battle for the Soul of Artificial Intelligence

    With every breakthrough, computer scientists are pushing the boundaries of artificial intelligence (AI). We see it in everything from predictive text to facial recognition to mapping disease incidence. But increasingly machines show many of the same biases as humans, particularly with communities of color and vulnerable populations. In this episode, we learn how leading technologists are disrupting their own inventions to create a more humane AI.
