Human or Algorithm – Who decides our future in the age of Artificial Intelligence? The power of digital corporations in Silicon Valley is already overwhelmingly large, posing a threat to democracy and freedom. Paul Nemitz and Matthias Pfeffer compellingly demonstrate how current attempts at ethical regulation of Artificial Intelligence fall short. Nemitz is a member of the Federal Government's Data Ethics Commission and played a key role in the introduction of the EU General Data Protection Regulation. Pfeffer works as a freelance TV journalist and producer focusing on Artificial Intelligence. The authors provide a thorough analysis, emphasizing the role of the public and the jeopardy facing journalism in digital times. They advocate for strict regulation of Artificial Intelligence and a rethinking of the principle of humanity, which must be defended against the principle of machines. Their book concludes with clear recommendations for action directed at politics, civil society, and especially the technical intelligence. Their expertise is urgently needed if we are to escape the stranglehold of technology and populism on democracy.
