Dear Maciej,
having working in the area of IoT inside the R&D team of a big Telco company I can't stress enough how important are the points you've highlighted in your article.

Tech people tend to foresee a brilliant use of the new technology they are delighted playing with, without attending on other important issues around it.

More focus is needed on who are going to use that tech, what is the real use for it (does it really cover any real user need), how is going to be used and maintained, what implications does it have in relation with already established processes....

However I believe history repeat itself with each new wave of technology breakthrough....

Great article anyway!
Congratulations
