This is the 4th and final book in the Artificial Superintelligence Handbook series and details the design of a Dimensional Cognitive Artificial General Intelligence as the final stage in the progression from designing and building narrow AI to building advanced human level Cognitive Artificial Intelligence. The series is a roadmap to the development of Superintelligence as well as many considerations, threats and hope for the survival of humanity. Each book in the series is a step toward what it takes to build a truly human level artificial cognition based on the way our human mind operates and functions and this book pushes the boundary to the extremes of human contextual cognition. In this book, I not only look at considerations for the final stage of Superintelligence or the use of dimensional context to comprehend and respond to a world of stimuli as fast as a human mind but also what this may mean for our world and the hope that it brings. I also discuss some of the newest AI methods and designs from self supervised neural nets and transformers to extreme Cognitive AI processors. The components of Superintelligence are being built by wealthy tech giants, governments and small labs. These designs are 'in the wild'. We must train the next generation to have any hope of competing in the new world of Artificial Superintelligence. Cognitive AI will also open the door to the extension of our own human cognition launching a new renaissance of human ingenuity, thought, creativity, innovation and opportunity and perhaps push the evolution of our species to that of extra terrestrial. Superintelligence may also be the only hope we humans have of saving the earth from a self afflicted destruction or one wrought by nature. Superintelligence is the best hope humans have for making our planet sustainable, ending the wealth gap, eliminating violence and war, ensuring freedom and one day soon, traveling to other planets and other solar systems. This book is dedicated to all who reach beyond the boundaries of their own existence to seek innovation solely for the benefit of those they will never meet, in worlds they will never occupy and in the hope of peace and tranquility they will never experience until they pass from this life.
