A lecture exploring the global sustainability transition from the technical, social, economic and environmental perspectives, and exploring the role of hackers in the greatest challenge humanity has ever faced.In this talk we will explore the current global sustainability situation, the possible ways forward and the role hackers have in this development. From the environmental, social, economic and technical perspectives we will identify the aspects where we as a global civilization are doing great, and where we are failing hard. While there is no single solution for the circular economy, energy transition, global equity, democracy and peace, we will identify robust design patterns that the hacker communities can engage in, and improve. Where possible, the talk will be backed with most current scientific theories and data. Expect a broad and philosophical exploration rather than a deep technical dive. After the talk, a discussion workshop will beorganised to explore the points you find particularly interesting in more detail.
