Everyone is talking about digitization. Wonderful prospects for the future are being sketched out. Comfort and prosperity, better health and possibly digital immortality await us. But these new conveniences are only one side of the coin. Increasing dependence on digital technologies, the risk of total surveillance, mass takeover of human jobs by robots, the manipulation of public opinion, the threatening loss of human control over technology - this other side shows threatening features. This book paints a critical picture of tomorrow's world and shows what we can expect if we do not consciously shape digitalization and make ourselves completely replaceable.
