But, with more cities joining the Smart City revolution and investing in sensors and other IoT devices, the risk of a new tech bubble is rising. The same technology giants that helped Barcelona become a smart city are now pushing more pilots of newer technologies with little regard for solutions that already work and can be shared without incurring additional expenses.

Let’s consider a few of the most worrisome issues related to IoT today:

In the long run, we are being faced with a bunch of independent devices that can’t be managed by a single platform or protocol. Manufacturers are now being required to develop different versions for different standards, effectively increasing manufacturing and engineering costs, and reducing their market potential.
