The Age of Artificial Intelligence argues that AI is not just another tool, but a civilizational shift. Unlike previous technologies that extended human physical abilities, AI operates in the domain of cognition: it interprets, writes, summarizes, recommends, and predicts. The book explores how this affects work, education, media, relationships, democracy, and meaning itself. It argues that AI will automate many coordination and knowledge tasks, but make human judgment, responsibility, and moral accountability more valuable. It warns against cognitive atrophy, synthetic reality, loneliness mediated by artificial companions, and the concentration of power in a few companies. At its core, the book claims that AI is a revealing technology: it exposes what is hollow in our institutions and forces us to ask what humans are for. Its answer is clear: machines generate outputs, but humans must still judge, choose, and bear consequences.
