Here is Harari's basic thesis. Science and technology have solved many of the problems that preoccupied mankind since the dawn of his existence. More people today die from obesity than from starvation. If we haven't universalized the solutions yet, then we must keep at it. The point is, we have largely mastered nature. Now, modern people seek happiness, indeed have come to think of it as a right. In the future, people will use biotechnology and other forms of technology to create happiness for themselves. They will become like gods, “attaining divinity.” This is a very good thing; it means we can go beyond humanity, and “acquire for us divine powers of creating and destruction, and upgrade Homo sapiens into Homo Deus. Another great social project of the 21st century is to biologically re-engineer Homo sapiens so that it can enjoy everlasting pleasure.
