The development of modern information and communication technologies has enabled the spread of tools and procedures dedicated to the discretization of reality, already involving inconceivable and unprecedented swathes of informations. The diversity, volume and velocity of data has made possible a vast set of digital contents: this is not just a form of technical externalization, of data storage, or of symbolic representation, but also the tangible basis for a new form of power, ‘algorithmic governmentality’, which uses the mathematical analysis of (...) this vast gathering of data to prescribe and proscribe particular concrete behaviours. Evaluating these procedures for the discretization of reality, together with processes of dividualization, data behaviourism and personal profiling, this article examines the complex of techniques applied to digital contents. The basis for this examination is here the Deleuzian concept of stratoanalysis: this will initially involve studying the forms and spaces generated and composed by digital technologies, so as to assess the viability of the concept of ‘digital stratum’. By then analysing the relationship between the anthropomorphic stratum and the digital stratum, and the way that algorithmic governmentality strives to control this relationship, it will become possible to propose a line of flight that sets out and sets off from this logic of control.
