Hang on. You caught that, right? It works! After years of failed demos, public sputters, and worrisome silence, Ara works. About 30 people within ATAP are using Ara as their primary phone. Camargo actually has the luxury of worrying about things like aesthetics, rather than whether it’ll turn on. “Please pay no attention to how it looks,” he tells me, flipping the blocky smartphone over in his hands, “because it’s a prototype.” It’s not a concept, not an idea, not a YouTube video. It’s a prototype. Developer kits for Ara will be shipping later this year, and a consumer version is coming in 2017. “We have now built all the key components of the platform,” Camargo says. Ara is no longer an experimental part of ATAP: It just became its own division within Google. Now it’s time to find out if there’s room left for another smartphone revolution.
