This paper presents a critique-of-humanism reading of The Theory of Educational Technology (2023) by Rupert Wegerif and Louis Major, drawing on Paul B. Preciado’s biopolitics and Jacques Derrida’s hauntology. It explores how Wegerif and Major address the concept of future humans and their interaction with social structures, their use of Heidegger’s Techné to frame technological engagement, and the knottiness of bio-socio-technical systems and agency. The paper also evaluates their proposed framework for designing educational technologies that foster productive dialogue. While this analysis serves as a book review in educational technology and dialogic space, it also offers a commentary for those interested in posthumanist analysis approaches.
