Hui’s “Cosmotechnics” challenges the assumption that technology constitutes a single universal trajectory. Rather than treating technical development as an autonomous sequence moving from ancient craft to modern enframing, he asks how technical activity is embedded in different relations among cosmos, morality, culture and social order. Cosmotechnics names the unification of cosmic and moral orders through technical practice, thereby relocating technology within the realities that enable and constrain it. The concept’s theoretical force lies in exposing technological universalism as a historical and political construction intensified by colonisation, modernisation and globalisation. Hui’s method is diagnostic and comparative: he revisits philosophy, anthropology and the history of technology to show where apparently universal accounts suppress regional epistemologies and technical facts. The essay bridges philosophy of technology, decolonial thought and comparative epistemology by replacing the question of alternative technologies with the more demanding problem of plural technical worlds. Its contribution is not cultural relativism, but a framework for thinking technological multiplicity without reducing difference to decorative variation.
