Technology is a host of social, material, and epistemic transformation techniques, tools, and methods. The common perception of digital technology today is that it is determined, even over-determined. This volume suggests a different view: the digital is indeterminate. Mobilising insights from philosophy, art and architecture theory, mathematics, computer science and anthropology, it situates digital indeterminacy within the wider context of material and immaterial processes, causations, triggerings, and their performative working. The book's tripartite structure reflects technology's inherent capacity to transform knowledges, practices, and time. Part I: Social-Digital Technologies juxtaposes arguments for machinic indeterminacy to those of overdetermination in blockchain, cognitive augmentation, and digital ideology. Part II: Spatial, Temporal, Aural and Visual Technologies delves deeper into received ideas about technologies for building spatial structures, manufacturing instruments and constructing the visual space. Part III: Epistemic Technologies analyses the use of plasticity in cognitive science, contingency in thinking habits, ontogenesis in experimental computing, and divination techniques with an inbuilt margin of indeterminacy.
