This presentation will introduce Superkilogirls, a research collective founded by Camila Galaz (USA/AUS), Ana Meisel (UK), and Lua Vollaard (NL). Established in 2024, the project investigates the often-overlooked contributions of women in computing infrastructures, tracing a trajectory from weaving machines and switchboards to the advent of semiconductors. Central to our research is the concept of the 'kilogirl', a tongue-in-cheek mid-20th-century unit measuring computing power based on the labour of female operators. By examining this metric, we explore the labour which has been historically marginalized, dismissed as peripheral rather than central to technological history within dominant narratives. Through a speculative framework, we question the inevitability of technological development and emphasize the human scale of computing. This presentation will also reflect on our recent residency within the Digital Cultures Lab at the Nieuwe Instituut in Rotterdam, where we began developing our upcoming project, "A Manual for Superfluous Motions." This publication reinterprets historical and contemporary documentation of computer component production, uncovering friction, sabotage, and moments of non-standardization that emerge beyond the logic of the production line.
