The introduction chapter positions algorithmic information ordering as a central practice and technology in contemporary digital infrastructures, a set of techniques that serve as 'levers on reality' (Goody).While algorithms used in concrete systems may often be hard to scrutinize, they draw on widely available software modules and well-documented principles that make them amendable to humanistic analysis.The chapter introduces Gilbert Simondon's mechanology and provides an overview of the structure and argument of the book.
