How to use information rather than submit to it? Does the living have a digital logic? Is the internal structure of the universe composed of information? Is the Internet generating a collective brain? Ever since Homo sapiens, armed with his electronic machines, learned to unlock the secret of information and its alchemy by digitizing it, he has liberated hyperinformation. This force would be a subtle alloy between matter and thought, the animate and the inanimate, the virtual and the real. For the first time in the history of humanity, technology seems to engender a collective intelligence. Does this mean that reason really becomes alien to itself, potentially hostile and dangerous? Or are we witnessing the happy dawn of a new era? Homo sapiens 2.0 offers a journey into the mysteries of the human brain, into the mysteries of genes and memes (their mental equivalent), into the secrets of language, religions and new technologies. From René Girard to Richard Dawkins, from Teilhard de Chardin to Joël de Rosnay, the author recounts the saga of thought in the virtual age. Between each chapter, "Interludes" allow you to travel through literary works or enlightening scientific experiences.
