There are a lot of numbers flying around about the Internet of Things. Gartner has IoT hitting 25 billion devices hitting $263 billion by 2020. Cisco sees it hitting $19 trillion by 2025 with an impact ten times the Internet itself, which is at least one of the ten most important inventions of our species. But for all the statistics, the prediction we’re most excited about is McKinsey & Company pegging 40 percent of the value of the Internet of Things on its interoperability. And, of course we know interoperability is synonymous with ten little syllables: application programming interface (What is an API?). The API will literally be what makes or, in the case of proprietary thinking, breaks the interconnected world of the Internet of Things.
