A comprehensive political & design theory of planetary-scale computation proposing that The Stack -- an accidental megastructure -- is both a technological apparatus & a model for a new geopolitical architecture What has planetary-scale computation done to our geopolitical realities? It takes different forms at different scales -- from energy & mineral sourcing & subterranean cloud infrastructure to urban software & massive universal addressing systems; from interfaces drawn by the augmentation of the hand & eye to users identified by self -- quantification & the arrival of legions of sensors algorithms & robots Together how do these distort & deform modern political geographies & produce new territories in their own image? In The Stack Benjamin Bratton proposes that these different genres of computation -- smart grids cloud platforms mobile apps smart cities the Internet of Things automation -- can be seen not as so many species evolving on their own but as forming a coherent whole an accidental megastructure called The Stack that is both a computational apparatus & a new governing architecture We are inside The Stack & it is inside of us In an account that is both theoretical & technical drawing on political philosophy architectural theory & software studies Bratton explores six layers of The Stack Earth Cloud City Address Interface User Each is mapped on its own terms & understood as a component within the larger whole built from hard & soft systems intermingling -- not only computational forms but also social human & physical forces This model informed by the logic of the multilayered structure of protocol "stacks" in which network technologies operate within a modular & vertical order offers a comprehensive image of our emerging infrastructure & a platform for its ongoing reinvention The Stack is an interdisciplinary design brief for a new geopolitics that works with & for planetary-scale computation Interweaving the continental urban & perceptual scales it shows how we can better build dwell within communicate with & govern our worldsthestackorg
