The Fourth Industrial Revolution builds on the Digital Revolution, representing new ways in which technology becomes embedded within societies and even the human body. The Fourth Industrial Revolution is marked by emerging technology breakthroughs in a number of fields, including robotics, artificial intelligence, nanotechnology, quantum computing, biotechnology, The Internet of Things (IoT), decentralized consensus, 3D printing and autonomous vehicles. The biggest impact of the Fourth Industrial Revolution is to improve the quality of life, reduce inequality of the world’s population and raise income level.
