Internet of Things (IoT) is a lot like that elephant. The owner of a Fitbit might see it as technology to get the wearer off the couch. The homeowner who installed a Nest thermostat might think IoT is a way to lower his or her utility bills.
To an athlete wearing a Polo Tech Shirt, IoT is the path towards a leaner, meaner body. Clearly, they are like those blind men whose impressions of IoT has been defined by their personal, and perhaps myopic, experiences.
