Abstract (EN): This second edition offers an updated and critical analysis of artificial intelligence as a sociotechnical phenomenon in the context of big data expansion. The book reviews the development of symbolic and sub-symbolic models and their institutional deployment in healthcare, mobility, finance, and government. New content reflects recent breakthroughs in generative AI, the European AI Act, and the restructuring of labor ecosystems between 2023 and 2025. Key challenges such as algorithmic opacity, governance, and skills disruption are examined through an interdisciplinary lens. The study calls for human-centered, ethically grounded regulatory frameworks that ensure democratic accountability and social resilience. Designed for researchers, policy experts, and digital ethicists, this work bridges theoretical insights with empirical policy reflections. Keywords (EN): Artificial Intelligence, Big Data, Algorithmic Governance, European AI Act, Generative AI, Labor Market, Digital Ethics, Human-Centered AI
