Schwab Klaus. 2017

Schwab argues that this revolution is different in scale, scope and complexity from any that have come before. Characterized by a range of new technologies that are fusing the physical, digital and biological worlds, the developments are affecting all disciplines, economies, industries and governments, and even challenging ideas about what it means to be human. 

The fourth industrial revolution, says Schwab, is more significant, and its ramifications more profound, than in any prior period of human history.
