Yuval Noah Harari (born February 24, 1976) is an Israeli historian, philosopher, and bestselling author. He is a professor at the Hebrew University of Jerusalem, known for his grand narratives that weave together history, biology, computer science, and philosophy to explore humanity's past and future.
Harari's trilogy — Sapiens (2011), Homo Deus (2015), and 21 Lessons for the 21st Century (2018) — has sold over 45 million copies worldwide and been translated into 65 languages. In these works and numerous public lectures, he has made extensive predictive arguments about artificial intelligence, dataism, biometric surveillance, and the future of human society.
Harari's predictions are not prophecies in the traditional sense, but academic extrapolations based on historical trends and technological developments. He warns that AI may create a 'useless class', algorithms will know us better than we know ourselves, and dataism may replace humanism as the dominant ideology. This site compiles 14 of his most representative predictions and evaluates those whose verification periods have arrived.
Core Message
"Humans face unprecedented revolutions: all old stories have gone bankrupt, and no new story has emerged to replace them. When biotechnology and information technology merge, they will create unprecedented means of control — not just over the external world, but over the human interior."

Harari Predictions All Prophecies 14 Q&A entries in total
AI will create a 'useless class'
Yuval Noah Harari: As AI and automation advance, billions of people will become economically useless, forming a massive 'useless class'. These people won't just be unemployed — they will be unemployable, because they can't do anything that AI can't do better.
Algorithms will know you better than you know yourself
Yuval Noah Harari: Algorithms will know humans better than they know themselves. By constantly monitoring your biometric data — heart rate, brain waves, blood pressure — algorithms will know your desires, emotions, and decisions before you do.
Dataism will become the new religion
Yuval Noah Harari: Dataism will replace humanism as the dominant ideology of the 21st century. In the dataist worldview, the universe consists of data flows, and the value of any phenomenon or entity is determined by its contribution to data processing. Humans are merely biochemical algorithms, no different in essence from computer algorithms.
Biometric surveillance will become the norm
Yuval Noah Harari: Governments and corporations will continuously monitor citizens' biometric data through under-skin sensors and wearable devices. The COVID pandemic will accelerate this process — people will accept continuous monitoring of temperature, heart rate, and blood pressure for health safety, and once collected, this data will never be relinquished.
AI will replace doctors, lawyers, drivers, and other professionals
Yuval Noah Harari: AI will replace the jobs of many professionals within decades — not just factory workers and truck drivers, but also doctors, lawyers, bankers, and teachers. AI will diagnose diseases more accurately than human doctors, and AI lawyers will be more efficient than their human counterparts.
The end of privacy
Yuval Noah Harari: Privacy will become an obsolete concept. When algorithms can infer your sexual orientation, political leanings, and emotional state from your biometric data, privacy becomes meaningless. Humans will live in a 'fully transparent' world.
Humans will become 'hackable'
Yuval Noah Harari: The human organism will become hackable. By understanding human biochemistry and collecting enough biometric data, external systems can predict and manipulate human desires, decisions, and emotions — just like hacking a computer.
Inequality between 'upgraded' and 'natural' humans
Yuval Noah Harari: Biotechnology will enable the rich to upgrade their bodies and brains, creating a biological upper class. Humanity may split into two species: enhanced 'god-men' (Homo Deus) with augmented abilities and unenhanced ordinary people. This will be the first true biological inequality in human history.
Crisis of liberal democracy
Yuval Noah Harari: Liberal democracy is losing its narrative advantage. In the 20th century, liberalism defeated fascism and communism, but it now cannot handle the challenges brought by the technological revolution. When algorithms understand politics and economics better than voters, democratic elections will become meaningless.
Global cooperation will fail
Yuval Noah Harari: The three existential threats facing humanity — nuclear war, climate change, and technological disruption — all require global cooperation to address, but the resurgence of nationalism makes such cooperation impossible. Nations will choose short-term national interests over long-term human interests.
AI will create art and music
Yuval Noah Harari: Artificial intelligence will be able to compose music, paint, write novels, and the quality will match or exceed that of human artists. Art will no longer be an exclusively human domain.
Data will become the most important asset
Yuval Noah Harari: Data will replace land and machinery as the most important economic asset. Whoever controls the data flow controls the future. Data giants — Google, Facebook, Amazon — will become more powerful than most nations.
AI will manipulate human emotions and decisions
Yuval Noah Harari: AI will not only analyze data but learn to manipulate human emotions. Recommendation algorithms will precisely deliver content that triggers specific emotional responses, and social media will become a tool for mass emotional manipulation. Humans will find it increasingly difficult to distinguish between their 'genuine will' and 'artificial will' guided by algorithms.
AI will master language and control civilization
Yuval Noah Harari: AI mastering language will be a turning point. Language is the operating system of human civilization — law, religion, economics, and politics are all built on language. When AI can wield language better than humans, it gains the ability to manipulate and generate the cultural artifacts that underpin civilization.

Biometric surveillance will become the norm
Yuval Noah Harari: Governments and corporations will continuously monitor citizens' biometric data through under-skin sensors and wearable devices. The COVID pandemic will accelerate this process — people will accept continuous monitoring of temperature, heart rate, and blood pressure for health safety, and once collected, this data will never be relinquished.
The COVID-19 pandemic did significantly accelerate health surveillance technology adoption — health codes and contact tracing apps spread globally, and wearable health monitoring expanded dramatically. However, as of 2025, under-skin sensors have not become mainstream, and most democracies scaled back mass surveillance programs post-pandemic. The trend exists but has not reached the predicted level.
AI will replace doctors, lawyers, drivers, and other professionals
Yuval Noah Harari: AI will replace the jobs of many professionals within decades — not just factory workers and truck drivers, but also doctors, lawyers, bankers, and teachers. AI will diagnose diseases more accurately than human doctors, and AI lawyers will be more efficient than their human counterparts.
As of 2025, AI has demonstrated capabilities exceeding some human professionals in medical diagnosis (e.g., radiology image analysis) and legal document processing. Self-driving taxis (Waymo) operate commercially in some cities. But AI has not truly 'replaced' these professions — doctors, lawyers, and drivers remain widely employed. AI serves more as an assistive tool than a replacement. The direction is correct but the degree falls far short of the prediction.
Crisis of liberal democracy
Yuval Noah Harari: Liberal democracy is losing its narrative advantage. In the 20th century, liberalism defeated fascism and communism, but it now cannot handle the challenges brought by the technological revolution. When algorithms understand politics and economics better than voters, democratic elections will become meaningless.
As of 2025, global democracy does face serious challenges: populism continues to rise in the US and Europe, social media algorithms intensify political polarization, and AI-generated disinformation interferes with elections. Freedom House has documented democratic backsliding for consecutive years. But liberal democracy has not collapsed — most democratic nations continue to function and hold elections. The crisis trend exists but has not reached the point where 'democratic elections become meaningless'.
Global cooperation will fail
Yuval Noah Harari: The three existential threats facing humanity — nuclear war, climate change, and technological disruption — all require global cooperation to address, but the resurgence of nationalism makes such cooperation impossible. Nations will choose short-term national interests over long-term human interests.
As of 2025, this prediction closely matches reality: the Paris Climate Agreement is weakly enforced with the US withdrawing twice; the Russia-Ukraine war and US-China rivalry have deepened global geopolitical fragmentation; global cooperation on AI governance has progressed slowly with nations going their own way; WHO's coordination capacity was widely questioned during the pandemic. Nationalism and protectionism have indeed become the main obstacles to global cooperation.
AI will create art and music
Yuval Noah Harari: Artificial intelligence will be able to compose music, paint, write novels, and the quality will match or exceed that of human artists. Art will no longer be an exclusively human domain.
As of 2025, this prediction has largely come true: Midjourney, DALL-E, and Stable Diffusion generate high-quality art; Suno and Udio compose complete music; ChatGPT and Claude write poetry and fiction. AI-generated art won a state fair competition (Colorado, 2022), and AI-composed songs trend on streaming platforms. Art is indeed no longer an exclusively human domain.
Data will become the most important asset
Yuval Noah Harari: Data will replace land and machinery as the most important economic asset. Whoever controls the data flow controls the future. Data giants — Google, Facebook, Amazon — will become more powerful than most nations.
As of 2025, this prediction closely matches reality: the world's most valuable companies are almost all data-driven tech firms (Apple, Microsoft, Nvidia, Google, Amazon, Meta). Their market caps exceed the GDP of most nations. AI training data is treated as a strategic resource, and nations compete fiercely over data sovereignty. The EU's GDPR and China's Data Security Law emerged precisely because of the recognized centrality of data.
AI will manipulate human emotions and decisions
Yuval Noah Harari: AI will not only analyze data but learn to manipulate human emotions. Recommendation algorithms will precisely deliver content that triggers specific emotional responses, and social media will become a tool for mass emotional manipulation. Humans will find it increasingly difficult to distinguish between their 'genuine will' and 'artificial will' guided by algorithms.
As of 2025, this prediction has clearly materialized: TikTok, YouTube, and Instagram recommendation algorithms have been proven to effectively manipulate user emotions and behavior (leaked internal documents confirmed Facebook knew its algorithms worsened teen anxiety and depression). Social media addiction is widely studied, and multiple countries regulate algorithmic recommendations. AI-generated deepfakes proliferated during the 2024 US election. Users in filter bubbles struggle to distinguish autonomous choices from algorithmic guidance.
AI will master language and control civilization
Yuval Noah Harari: AI mastering language will be a turning point. Language is the operating system of human civilization — law, religion, economics, and politics are all built on language. When AI can wield language better than humans, it gains the ability to manipulate and generate the cultural artifacts that underpin civilization.
As of 2025, large language models (GPT-4, Claude, etc.) have indeed achieved revolutionary breakthroughs in language ability, matching or exceeding human performance in many tasks: writing legal documents, generating news, composing poetry and fiction, passing bar and medical exams. AI has begun influencing information dissemination and public discourse. But AI has not truly 'controlled' civilization — legal, political, and religious systems remain human-led, with AI serving as a tool rather than an autonomous agent. The direction is highly accurate, but 'control' has not been achieved.
AI will create a 'useless class'
Yuval Noah Harari: As AI and automation advance, billions of people will become economically useless, forming a massive 'useless class'. These people won't just be unemployed — they will be unemployable, because they can't do anything that AI can't do better.
