Fictional Narratives Are the Core Engine of Human Cooperation
The only reason humans can build large-scale cooperative networks beyond 150 people is that we can believe in shared fictional stories — religion, nation-states, money, corporations. These 'inter-subjective realities' exist only in collective imagination yet have the power to change the real world.

The Cognitive Revolution (70,000 Years Ago) Is the True Starting Point of Human History
Around 70,000 years ago, Homo Sapiens underwent a 'Cognitive Revolution' — a genetic mutation in the brain enabled them to use language to describe things that don't exist. This leap transformed sapiens from an ordinary African animal into a species that conquered the Earth. Agricultural and Industrial Revolutions are extensions of this cognitive capacity.

Dataism: Algorithms Will Become the New Gods, Humanity Faces the Crisis of Being Surpassed
In the 21st century, data processing capacity will become the ultimate source of power. As algorithms surpass humans in understanding human behavior, individual free will and liberal order will face fundamental challenges. Most humans will become 'economically useless' — not enslaved, but forgotten in the grand data streams of algorithms.

History Has No Direction — Progress Is a Narrative Illusion
The Agricultural Revolution was a disaster for most people: worse diet, more labor, shorter lifespans. The Industrial Revolution created wealth and unprecedented scales of war. Harari warns: we cannot assume technological progress automatically equals increased human happiness.

Inter-Subjective Reality Framework
Categorizes social phenomena into objective, subjective, and inter-subjective reality to understand the nature of institutions and culture
A dollar bill is objectively a green piece of paper, individually one may or may not believe in its value, but because billions collectively believe in its worth (inter-subjective reality), it gains the power to purchase food, armies, and political power.

"Useless Class" Hypothesis
AI automation will create a vast population that is economically and militarily irrelevant — a fundamental threat to modern democracy
The 19th century Industrial Revolution made agricultural workers 'useless,' but factories created new jobs. Harari argues AI Revolution differs — machines replace not just physical but cognitive labor, and humans may have no new economic value to offer.

History as Extension of Biology
Uses evolutionary biology to explain historical phenomena, revealing tension between deep animal instincts and cultural narratives in human behavior
Human preference for sugar and fat stems from evolutionary pressure (survival advantage in calorie-scarce eras), but in calorie-abundant modern societies, this instinct causes obesity epidemics. Cultural narratives (the diet industry) are attempts to override biological instincts.
