Wednesday, March 25, 2026 • Duration 44:11
The Moonshot Podcast is back!
In the season 2 premiere, X’s Captain of Moonshots Astro Teller explores how three X projects developed technology to transform the future of healthcare.
He first sits down with Kathryn Zealand and Anna Roumiantseva from Skip to hear about how the world’s first “e-bike for walking” evolved from their team’s mobility moonshot at X. They recount how an early prototype of Skip’s powered pants helped carry a colleague to top of the Salesforce Tower, and share how the product has developed since spinning out into an independent company (Astro even tries a pair on for size to see their progress firsthand).
Microelectronics expert Will Biederman then joins Astro for a conversation about the origins of Project Iris, a computerized contact lens designed to help measure diabetes risk, which laid the foundation for the continuous glucose monitors that millions of people use today. Finally, Astro chats with Verily CEO Stephen Gillet to hear about his mission to make precision healthcare accessible to anyone, anywhere, at any time.
