The Internet of Things keeps promising us a smarter future: fridges able to replenish themselves by automatically ordering food at a local grocery store (in-fridge delivery included!), bridges warning the oncoming cars about a frozen surface, or smart gear that monitors your health and delivers real-time data straight to your doctor’s iPhone. While all of this may soon be within the reach of our hands, we still have to be aware of the massive machinery behind the scenes that makes dreams become reality. Without myriads of IoT technologies that surround us, these dreams would never come true.
