Epilogue Summary
In the Epilogue, Harari reflects on the rise of AI and its implications for humanity, drawing from his personal experiences after publishing Homo Deus. Initially trained in history, Harari found parallels between past historical events and the unfolding AI revolution. He was given “the reputation of an AI expert” (396), which compelled him to learn more about the subject.
Harari describes how new information technologies, such as AI, can significantly reshape societies, just as previous revolutions like the printing press and Industrial Revolution did. However, he cautions against simplistic comparisons, emphasizing the potential dangers of AI, including its ability to make independent decisions and create new challenges for political, economic, and social systems. AI could lead to catastrophic consequences, as history has shown with other powerful systems that lacked checks and balances.
Harari closes the book by urging humanity to avoid both naive optimism and excessive cynicism when dealing with AI. Instead, he advocates for creating balanced networks and institutions that promote wisdom and sustainability, reminding the audience that, while human civilization is fragile, the decisions made about AI’s development will “determine whether summoning this alien intelligence proves to be a terminal error or the beginning of a hopeful new chapter in the evolution of life” (404).
Epilogue Analysis
The short Epilogue to Nexus is the point at which Harari becomes most explicit in his address to the audience. He preaches the need for unity in the face of the rise of artificial intelligence, even if most people cannot understand the way in which the technology works. Nexus seems like a direct response to this issue, in which a historian rather than a scientist attempts to wrangle with the issues that may potentially be caused by artificial intelligence and The Power Dynamics of Information Control.
As such, the book becomes a demonstration of the way in which Harari is practicing what he preaches. He is calling for people to set aside any limitations they might have with regards to technical knowledge and to strive to understand AI on their own terms. He is a historian, so he situates AI in a historical context. The book is a model for understanding an emergent technology as an individual, so as to prepare for the future as a society.
At the same time, however, Harari accepts that the cooperation that he urges will be difficult, as it is also an international necessity. Each individual is responsible, but so are the nation states that seem so diametrically opposed to cooperation. Since nation states—and particularly those run by dictators—seem like they will not be able to agree on The Importance of Self-Correcting Mechanisms in AI, the future of AI seems fraught with issues. In this respect, Harari’s call to action takes on a more desperate tone. He has identified the flaws in the system but he recognizes his limited capacity to change the world in this way. He cannot depose the dictators, nor can he prevent the emergence of other dictators in the future.
In spite of this sense of individual futility, Harari does not give up hope. In spite of his earlier criticisms of naivety, he never abandons his optimism. Harari sincerely believes in humanity’s capacity to change and accommodate technology like AI, so the prophetic tone in the Epilogue takes on a more optimistic tone than might be expected from his discussion of gulags, totalitarianism, and the relative powerlessness of the individual.
