The Unknowability of Autonomous Tools and the Liminal Experience of Their Use

In the extant theoretical discourse on sociotechnical systems, the relationships between inputs and outputs of technologies are assumed to be knowable to human agents, occasionally ex ante and always ex post. Recently, a new breed of autonomous tools has emerged, which can independently learn and execute novel actions. The input-output relationships of these tools, however, are unknowable to human agents both ex ante and ex post. This calls for analysis of how humans experience the enactment of socio-material agency while interacting with autonomous tools. To this end, we conduct an exploratory, theory building, comparative case study at one of the world's largest semiconductor manufacturers. We investigate how chip designers interact with two families of design technologies: one following a traditional designer-centric approach in which the designer knows what outputs particular inputs to the tools will generate and another relying on autonomous tools that continually surprise the user. Our inquiry reveals significant differences in designers' experiences of using different tools. When using autonomous tools, designers' experience of enacting socio-material agency becomes liminal, a state of continuous emergence, in which interactions with the tools are marked by ambiguity, and the design is moved forward along multiple design trajectories in accordance with a multifarious temporality. These insights require us to expand upon several dominant views on the enactment of socio-material agency and necessitate novel thinking on the role and impact of autonomous tools in future work systems as well as on how design and innovation proceeds under such conditions.
