On September 23, we held the Online Seminar “Digital Public Infrastructures” with the participation of Jack Linchuan Qiu (University of Singapore), Seda Gürses, (TU Delft), and Geert-Jan Bogaerts (PublicSpaces). The event, chaired by Thomas Poell, looked into whether there is a need for digital public infrastructures. It asks: Which digital public services are needed and how should these be developed? What resources are needed to make public digital services successful?
