NASA’s Planetary Defense Officer, Lindley Johnson, divulges the plan to protect earth from asteroids with a first-of-its-kind planetary defence system. Plus, we talk to the Co-Founder and President of Nommi, Buck Jordan, about their robotic kiosks and the future of kitchens. Also, David Nussbaum, the Founder and CEO of PORTL, explains their holoportal system, including how users can appear in a full-size, lifelike 3D form to interact with people anywhere around the world. In Socially Speaking, we chat about Adele's Spotify change that prompts records to play tracks in subsequent order, as artists have designed, rather than via a shuffle default.
