"The singularity" is a term that any science-fiction fan and/or computer scientist will have heard. I will confess that the definition and implications of it weren't that clear to me before starting this book. Shanahan does a very good job at defining it, considering how artificial general intelligence could possibly be achieved, how it can lead to singularity, and what could be the impact of this, considering both technical and philosophical questions, at a very accessible and pretty engaging level. A thoroughly interesting read - although it definitely adds to the general sense of World Anxiety instead of alleviating it ;)
