The book sets out to examine possibilities of the future of Homo sapiens. The premise outlines that during the 21st Century, humanity is likely to make a significant attempt to gain happiness, immortality and God-like powers. Throughout the book, Harari openly speculates various ways that this ambition might be realised in the future based on the past and present.
