The book 'The Future of Humanity' written by Michio Kaku in 2011 discusses how exponential technologies will change the way we live and work. The book covers topics such as genetics, nanobots, stem cells, and the next unified interface which will be first glasses/lenses and then just your brain and AR all enabled by AI. The book also talks about how we are making our way to become a United Planet Civilization and eventually a Star-Galactic-Extragalactic civilization. The book provides a 3-minute overview of the exponential growth, the Cave Man Principle, the next unified interface, and the wisdom of the crowd.
