Liang began thinking about this a decade ago, after he left a job at Google to cofound a startup that monitored people's behavior on mobile devices to provide services like automatically tracking mileage expenses. "I'm obsessed with getting data and understanding data," he confesses. "In my first startup, we used a lot of iPhone sensors: location, GPS, Wi-Fi, motion. The one sensor we didn't use was the microphone."
He calculated that you could store a lifetime of audio on a 2-terabyte USD drive. "Then I can search for everything I heard in my whole life," he says. "My parents have already died. I really wish I can just retrieve their speech."
