We are facing a technological revolution that will fundamentally change our daily life, work and our society. Me (Igor Timofeev) wrote about this in 2017 in my previous series of books Digital World 1,2,3,4 and 5. In this NEW book I want to continue the description of very fast changes in digital world surrounding us. Robots, internet of things, artificial Intelligence and cryptocurrencies are the elements of this World.In this book I am doing some research on the development of Quantitative Evaluation (QE) of Intellectual Property (IP) and Digital Assets (DA).I gathered in this book a lot of mathematical tasks too. These tasks should be used to prepare the teenagers for entering this new, sometimes very dangerous and rapidly changing Digital World of The Fourth Industrial Revolution.
