During the reading of this techno-thriller, we ask many questions because the author - a philosopher as well as geek - exposes very interesting ideas on the opposition between hierarchical society and network society, the themes of control and collaboration, enslavement and freedom, formatting masses and individuation. Also arose the question of consciousness and identity: how to articulate these concepts in an individual whose brain has a powerful neural implant? A book to recommend, therefore, to all those who use science fiction to question the situation facing humanity tomorrow. And to this end, I added a link on Prey by Michael Crichton.
