In Part 1, I gave IoT technologies a B-. In Part 2, we further explore why they deserve this grade while also remaining upbeat about the future. IoT technologies are generally in a state of early adolescence: They preview huge potential but face growing pains for now. To accelerate adoption, IoT must still overcome multiple barriers, including complexity, interoperability, and standards. Meanwhile, advances in areas such as big data analytics and blockchain will expand IoT markets and add new use cases. You can read my view on industry’s role to fulfill the promise of IoT and resolve its current challenges in, “Another Brick in the Wall: Barriers to IoT Adoption.” Our next issue will focus on, “Security: IoT’s Biggest Challenge.”
