Learning a new skill on ApprenNet is all about screens. Learners watch screens, record responses with screens, and interact with each other through screens. So what is the impact of all that screen time? The time we spend watching screens affects the way we learn, connect, and interact with the outside world. Developments in digital technology are growing so quickly that scientific studies struggle to keep up. We can step into virtual reality films to experience and lose ourselves within those worlds. Drones make it possible for us to watch and learn from the horrors and complexities of war. Some screens can read our emotions, track them and respond by suggesting content we may want to watch or hear. This series of TED Radio Hour podcasts hosted by Guy Raz dives into the way screens are changing us and our future.
