Microsoft plans to spend $5 billion on the internet of things, and it’s more than the usual shell game that big firms play with these sorts of announcements. We discuss its plans on this week’s podcast. We also talk about Qualcomm’s new vision chips for edge devices, what it means that apps are disappearing from the Apple Watch and Kevin’s thoughts on getting Alexa or Google to talk to you. I review the Nest doorbell before we answer a question on Z-wave and ZigBee for a listener. This week’s guest is Poppy Crum, chief scientist at Dolby Laboratories, who talks about where hearables are today, what’s changing and some of the cool things we can look forward to. We also dig into the things that kill your hearing, and how we perceive sound. Listen and learn, y’all.
