Gandy’s “Cyborg Urbanization” mobilises the cyborg not as a technological fantasy but as an ontological strategy for analysing the contemporary city’s hybridisation of body, machine, infrastructure and nature. Its iconic idea is that urbanisation increasingly dissolves distinctions between organic and inorganic systems, producing monstrous, unstable and technologically mediated assemblages. The theoretical contribution is to connect Haraway’s cyborg thought with urban political ecology, showing that cities are not simply built environments but socio-natural and techno-organic metabolisms. Methodologically, the article proceeds through theoretical genealogy, drawing from science fiction, cybernetics, architectural theory, bodily technologies and urban infrastructure to expose anomalies in dominant urban thought. Its conceptual operation is hybrid urban ontology: the city becomes a field where corporeal, infrastructural and ecological boundaries are continuously reconfigured. The bridge to the wider field joins urban political ecology, posthuman theory, infrastructure studies, architectural criticism and cultural geography, making the cyborg a critical figure for urban complexity.
