You can teach about 2G, 3G, 4G radio networks without the need to explain the business that it’s behind it. Technology experts are far from being involved in the strategies of network operators.
For the IoT, it’s different. The IoT is in the hands of small companies, with disruptive ideas. The IoT is a playground where those who conceive the idea, the business opportunity, can also be or are closely related to the makers, those who make it become reality.
You can’t be an expert of the IoT without knowing how to make business out of it. You can’t have a disruptive and successful idea, without knowing how to build your solution.
True IoT experts are both strategists, and makers.
