Every day, data is collected about how you live. This data is owned by large technology companies in the US and China. Google, Facebook, Amazon, and TikTok have become such a big part of society that important decisions are being moved from democratic assemblies to closed boardrooms. On the one hand, technology makes our lives more exciting and richer. At the same time, it can create economic disparities the world has never seen before. Technology companies are developing increasingly advanced forms of artificial intelligence that can solve key tasks, but also threaten our freedom more fundamentally than ever before in history. Hilde Nagell shows how it is possible to return control to the people and to democracy. She has spoken with politicians, philosophers, trade unionists and technologists, and ultimately proposes a Nordic model for digitalisation and data sharing. It is fundamental that data should be viewed as a collective good.
