124. A 3G retrospective, Spotify releases its Car Thing, and Meta's speech-generated worlds

With AT&T becoming the first of the major U.S. carriers to start shutting down its 3G network, we look back at the advances that the network gave rise to and how its capabilities compared to the shifts of 4G and 5G. Plus, Spotify releases its first device: Car Thing, a thin touchscreen designed to ease access to its phone-based service in the car. We offer our take on its goals and potential. Finally, Meta continues its string of tantalizing demos with its mashup of VR and AI. We look at the potential for speech as the ultimate natural interface for artificial reality.
