McLuhan’s central move is to stop asking what a medium says and ask what it does — to the body, the senses, the shape of a society. “The medium is the message” is less a slogan than a method: a press, a telegraph, a television changes how people perceive and organize long before anyone examines its content. He reads the wheel as an extension of the foot and electric media as an extension of the nervous system, each extension quietly numbing the faculty it amplifies.
Read now, the book feels less like media theory than early philosophy of AI: a warning that any tool powerful enough to extend a human capacity also reshapes the human using it, usually too quietly to notice. Asking what a chatbot or a recommendation feed does to attention and memory is McLuhan’s question, in his terms, six decades on.
