The main idea of the book is that the main driving factor in the 21st century will be the development of three super technologies: artificial intelligence, nanotechnology and biotechnology, which have the potential to radically change the life of society.

It follows that preventing catastrophe and prolonging people’s lives is humanity’s top priority for the coming decades. The book is aimed at a wide range of readers.
