Extinction Internet is not merely an end-of-the-world phantasy of digital technology that one day will be wiped out by an electromagnetic pulse or the cutting of cables. Rather, Extinction Internet marks the end of an era of possibilities and speculations, when adaptation is no longer an option. During the internet’s Lost Decade, we’ve been rearranging the deck chairs on the Titanic under the inspirational guidance of the consultancy class. What’s to be done to uphold the inevitable? We need tools that decolonize, redistribute value, conspire and organize. Join the platform exodus. It’s time for a strike on optimization. There is beauty in the breakdown. ‘Extinction Internet’ is Geert Lovink’s inaugural lecture, held on November 18, 2022 as Professor of Art and Network Cultures, within Modern and Contemporary Art History, Faculty of Humanities, University of Amsterdam.
