Follow-up on Garden (spoiler alert: nope) leads to a discussion of the evolution of keeping in touch, from actual pen pals through the IM years to the social media era, and the shifts in the nature of relationships that went along with it. Close relationships seem to make technological transitions more easily, but when one gets a little closer to hitting Dunbar’s number, it can get a little weird. Drew had an urgent topic come up before recording, though, so it was urgent that they discuss how awesome AirPods are. The main topic this episode is audio as an interface, which means talking about headphones, but that’s just the hardware. The interesting part is how technology is transforming the audible dimension of human life.
