Book excerpt: In the coming decades robots and artificial intelligence will fundamentally change our world. In doing so they offer the hope of a golden future, but there are dangers. This book looks at both the history of robots, in science and in fiction, as well as the science behind robots. Specific chapters analyse the impact of robots on the labour market, people’s attitudes to robots, the impact of robots on society, and the appropriate policies to pursue to prepare our world for the robot revolution. Overall the book strikes a cautionary tone. Robots will change our world dramatically and they will also change human beings. These important issues are examined from the perspective of an economist, but the book is intended to appeal to a wider audience in the social sciences and beyond.
