IOT and self-control are close to each other. Nevertheless, the difference should not be underestimated. Self-controlling objects are not necessarily dependent on the internet or networked structures.
However, overlaps cannot be dismissed out of hand: Thematic areas such as computing, Industry 4.0 or cognitive systems have similar logics and are at least partially networked with digital structures.
Basically, however, it can be said that the IOT is pursuing the goal of making information available as broadly as possible and would like to expand the possibilities for use over time.
