In this episode we discuss artificial intelligence, robotics and drones, which can create enormous benefits but also huge risks. For example, robotic manufacturing can result in better, cheaper goods, but may also displace a lot of workers who can't compete with the speed and lower costs of robots. In medicine, surgical robots can be more precise than human doctors, but as weapons of war, inexpensive armed drones can be used by almost anybody against anybody else, creating the possibility of global chaos. The guest is Steve Omohundro, scientist, author and entrepreneur who has long studied the interface between mind and matter. He cofounded the Center for Complex Systems Research at the University of Illinois, published the book “Geometric Perturbation Theory in Physics”, and is president of Self-Aware Systems, a think tank that works to ensure that intelligent technology is used for positive purposes only. He also serves on the advisory boards of the Cryptocurrency Research Group and the Institute for Blockchain Studies, and we also talk about Bitcoin and how it relates to the other fields.
