In his latest book titled Nexus – A Brief History of Information Networks from the Stone Age to AI, author Yuval Noah Harari describes the role that information networks have played in shaping society. A nexus is a connection or series of connections linking two or more things. It often refers to a central or focal point where multiple elements converge or interact. The term is used in various contexts to describe relationships or linkages within systems, networks, or concepts that are interconnected.
