A disease of man is his belief in progress. It promises him to be like God one day. To be able to be like God means: to overcome nature. In the end, man stands as a machine - perfect, prepotent, immortal: Homo Deus! This is the title of Yuval Noah Harari's bestseller, whose story of tomorrow culminates in a data religion whose God is the Great Algorithm. This latest vision of the new man supersedes all classical utopias since Thomas Morus. Created in the billionaire laboratories of Silicon Valley, it has long since found global acceptance. This new man no longer has a neuronal-based life story, no character, no face. How can we encounter such utopias from a Christian perspective? This is the question to which the volume aims to provide appropriate answers. Representatives from theology, philosophy, and the natural sciences address the problem with the help of the dual strategy of analysis and criticism.
