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.

Public lighting’s primary purpose is nighttime visibility for security and safety. How to meet so many requirements of so many stakeholders? The key to developing a good plan is to relate lighting to functions of public spaces, because street lighting is more than a technical requirement, a security need, or a design element. It can be thought of and utilized in terms of how the type, placement, and wattage affect how a street is perceived and used. With present-day used street lighting systems however, flexibility is expensive, as is maintenance and energy consumption. A new solution is to use LED lighting with a Direct Current power system. Advantages are a decrease in: energy conversions; material use; amount of switch- boxes; components; labour costs and environmental comfort. The overall implementation of LED and DC will result in better control and efficient maintenance due to integrated bidirectional communication. A challenge is the relatively high investment for these new solutions. Another challenge; DC is not a standard yet in rules and regulations. In the paper the transition to direct current public lighting system will be described with all the pros and cons. A new concept of public ownership, to overcome financial challenges will be discussed.
