They say that by 2020, there will be 50 billion connected things on the planet. This already includes your refrigerator, weighing scale, coffee machine, household lighting systems and intelligent assistants, and will very soon (if not already) extend to the cars you use to commute, the restaurants and pubs you visit and even the locomotives and aeroplanes in which you travel.
As good as they are on their own, it is only when smart devices connect to each other that their utility undergoes a phase transformation. Smart cars that speak to our home automation systems can provide our smart homes with advance information of our exact location on our commute back from work, initiating a series of workflows that will ensure that the lights come on and the air conditioning has cooled the house to the correct temperature so that our home welcomes us properly when we arrive. This is the power of the Internet of Things (IoT). And as much as we might marvel at all it has to offer us, the true promise of the connected world is still ahead of us.
