Talking about infrastructures in all their glorious invisibility has to rely on examples. Whether we introduce infrastructures as large scale irrigation systems or as the building we live in, makes a huge difference. In this talk I imagine infrastructures as mundane and close to users, which poses the question of where infrastructures start and where they end. The point I want to make is that tools and technologies are actively transformed into infrastructures (degree of compliance to Leigh Star’s famous catalogue of characteristics) and that this activity is inherently political.
