Final answer:
Security concerns are an obstacle to implementing the vision implied by the Internet of Things.
Step-by-step explanation:
The security concerns remain an obstacle to implementing the vision implied by the Internet of Things. There are several drawbacks and risks associated with the Internet of Things (IoT) that hinder its widespread adoption. These include the increasing gap between the technological haves and have-nots, also known as the digital divide, the loss of privacy, the risk of system failure, and the added vulnerability created by technological dependence. For example, a technological malfunction or a systematic attack could disrupt the functioning of critical infrastructure like nuclear power plants. Therefore, it is true that security concerns are an obstacle to implementing the vision implied by the IoT.
