Like any other technology there are challenges which make the viability of IoT doubtful.

Security is one of the major concerns of experts who believe virtually endless connected devices and information sharing can severely compromise one?s security and well being. Unlike other hacking episodes which compromise online data and privacy with IoT devices can open gateway for an entire network to be hacked.

One such flaw is well presented by Andy Greenberg on wired.com where he works with hackers to remotely kill his Jeep on the highway. Another very relevant example is provided by W. David Stephenson in his post Amazon Echo: is it the smart home Trojan Horse? You can estimate the amount of personal and private data the connected devices will be producing once they are on a network. The major challenge for IoT tech companies is to figure out how the communication in the internet of things realm can be made truly secure.
