First of all, I have to say that this book imbue me with comprehensive ideas about technology, war, education, science-fiction, fake news, religion, stories and of course homo sapiens. Unlike other historians, Harari is the historian of the future. That is because, he does not fighting with some stories or claims which are belong to some groups, he crave to find truth or best way for the future of the globe.
Furthermore, in the ancient times people could easily predict the near future, although they did not possessed cutting-edge technological devices. For instance, people who lived in X dynasty as a peasant, warrior or lower class member, could readily foresee plague, war or other incidents could harmed themselves fatally. However, in the technology era, next decade is unpredictable for people all over the world, even though they have up-to-date devices.
Besides these brilliant concepts, Harari explains secularism which is my favorite chapter in the book. For example, secular people should not be afraid of learning new things which contradicts deep-rooted beliefs. This is the most necessary feature for both ordinary and influential people, if we want to convert the world into paradise.
On the whole, throughout book, Harari strives to keep up with current affairs such as global warming, migration and so forth. He not only ask questions but also endeavour to find some answers. As a result, I, to some extent, support their valuable both questions and answers, and I suggest this book every people.
