یادداشت Masoud T

        I have read the Harari's Sapiens and Homo Deus that cover the past and future of humankind. Although I like his books and his attitudes toward history, but there are some flaws that make the new book, 21 Lessons for the 21st Century, like a science-fiction or fantasy book. In think the main weakness of the book is that the conclusion of each chapter is not coherent and not satisfying. In my opinion, the main lesson that is gained from the book is that we must stop worrying about the future and its problems, instead we should find the most important ones and pay attention to them.
