In tech, this was the smartphone decade. In 2009, Symbian was still the dominant ‘smartphone’ OS, but 2010 saw the launch of the iPhone 4, the Samsung Galaxy S, and the Nexus One, and today Android and iOS boast four billion combined active devices. Smartphones and their apps are a mature market, now, not a disruptive new platform. So what’s next?

The question presupposes that something has to be next, that this is a law of nature. It’s easy to see why it might seem that way. Over the last thirty-plus years we’ve lived through three massive, overlapping, world-changing technology platform shifts: computers, the Internet, and smartphones. It seems inevitable that a fourth must be on the horizon.
