This is an historical account of the development of an aspect of technology and of machines, leading to information technologies, the Internet and the Internet of Things. It points to an increasing trend towards these machines and devices becoming more and more independent of human intervention and control. We have not quite got there yet, but a clear trend can be observed nevertheless from mechanically controlled machines such as Al-Jazari’s Castle Clock which a naïve 13th century observer could have thought had a life of its own to modern smart kitchen and household appliances (from the Internet of Things) that really could be said to have a degree of independence. The paper makes use of actor-network theory as a lens for understanding the human and non-human elements of this historical trend.
