I've been writing about and doing, IoT for almost 20 years now and one of the things I am continually doing is seeing how I can use different technologies to further the state of the art in IoT. I've invested a lot of time and effort in seeing that IoT is successful, and finding innovative ways to look at IoT.
It turns out that close to 70% of IoT projects fail at the proof of concept phase. Why? because they are unable to deliver any lasting value to businesses and are thus abandoned. This is one reason why I believe that, even though IoT has been "about to explode" for over a decade, it has yet to deliver as well.
