Project Cybersyn was created under the Allende presidency in Chile to combat inflation. Because Cybersyn was never realized, existing scholarship on Cybersyn has not sufficiently analyzed the premises that informed it. The intellectual history of this project demonstrates that the structuralist economics that informed Cybersyn had removed the consideration of uncertainty from an older Keynesian model of money demand. Likewise, the intellectual father of cybernetics, Norbert Wiener, recognized the potential application of his system to social studies but advised against it. The consequence of both changes can be described as a move towards virtuality, meaning an interaction with an illusion as mediated by a computer. This description highlights the shift from treating social transformation as a potent possibility to a treatment of social relations as determinate and predictable. The central site of this interactive illusion was known as Opsroom, and it contributed to an illusion of power rooted in technology rather than politics.
