Yuval Noah Harari Quotes

As of 2016, humankind indeed manages to hold the stick at both ends. Not only do we possess far more power than ever before, but against all expectations, God’s death did not lead to social collapse. Throughout history prophets and philosophers have argued that if humans stopped believing in a great cosmic plan, all law and order would vanish. Yet today, those who pose the greatest threat to global law and order are precisely those people who continue to believe in God and His all-encompassing plans. God-fearing Syria is a far more violent place than the atheist Netherlands.

When people design web pages, they often cater to the taste of the Google search algorithm rather than to the taste of any human being.

While a good story must give me a role, and must extend beyond my horizons, it need not be true. A story can be pure fiction, and yet provide me with an identity and make me feel that my life has meaning. Indeed, to the best of our scientific understanding, none of the thousands of stories that different cultures, religions and tribes have invented throughout history is true. They are all just human inventions. If you ask for the true meaning of life and get a story in reply, know that this is the wrong answer. The exact details don’t really matter. Any story is wrong, simply for being a story. The universe just does not work like a story.
So why do people believe in these fictions? One reason is that their personal identity is built on the story. People are taught to believe in the story from early childhood. They hear it from their parents, their teachers, their neighbours and the general culture long before they develop the intellectual and emotional independence necessary to question and verify such stories. By the time their intellect matures, they are so heavily invested in the story, that they are far more likely to use their intellect to rationalise the story than to doubt it. Most people who go on identity quests are like children going treasure hunting. They find only what their parents have hidden for them in advance.
Second, not only our personal identities but also our collective institutions are built on the story. Consequently, it is extremely frightening to doubt the story. In many societies, anyone who tries to do so is ostracised or persecuted. Even if not, it takes strong nerves to question the very fabric of society. For if indeed the story is false, then the entire world as we know it makes no sense. State laws, social norms, economic institutions – they might all collapse.

If AI can suffer, then it is an ethical subject and it needs protection, it needs rights, just like humans and animals.

It takes a lot of courage to fight biases and oppressive regimes, but it takes even greater courage to admit ignorance and venture into the unknown. Secular education teaches us that if we don’t know something, we shouldn’t be afraid of acknowledging our ignorance and looking for new evidence. Even if we think we know something, we shouldn’t be afraid of doubting our opinions and checking ourselves again. Many people are afraid of the unknown, and want clear-cut answers for every question. Fear of the unknown can paralyse us more than any tyrant. People throughout history worried that unless we put all our faith in some set of absolute answers, human society will crumble. In fact, modern history has demonstrated that a society of courageous people willing to admit ignorance and raise difficult questions is usually not just more prosperous but also more peaceful than societies in which everyone must unquestioningly accept a single answer. People afraid of losing their truth tend to be more violent than people who are used to looking at the world from several different viewpoints. Questions you cannot answer are usually far better for you than answers you cannot question.

Consumerism tells us that in order to be happy we must consume as many products and services as possible. If we feel that something is missing or not quite right, then we probably need to buy a product (a car, new clothes, organic food) or a service (housekeeping, relationship therapy, yoga classes). Every television commercial is another little legend about how consuming some product or service will make life better.

In such a world, the last thing a teacher needs to give her pupils is more information. They already have far too much of it. Instead, people need the ability to make sense of information, to tell the difference between what is important and what is unimportant, and above all to combine many bits of information into a broad picture of the world.

The insight of polytheism is conducive to far-reaching religious tolerance. Since polytheists believe, on the one hand, in one supreme and completely disinterested power, and on the other hand in many partial and biased powers, there is no difficulty for the devotees of one god to accept the existence and efficacy of other gods. Polytheism is inherently open-minded, and rarely persecutes ‘heretics’ and ‘infidels’.

In the 300 years of the crucifixion of Christ to the conversion of Emperor Constantine, polytheistic Roman emperors initiated no more than four general persecutions of Christians. Local administrators and governors incited some anti-Christian violence of their own. Still, if we combine all the victims of all these persecutions, it turns out that in these three centuries the polytheistic Romans killed no more than a few thousand Christians. In contrast, over the course, of the next 1,500 years, Christians slaughtered Christians by the millions, to defend slightly different interpretations of the religion of love and compassion.

If we think in term of months, we had probably focus on immediate problems such as the turmoil in the Middle East, the refugee crisis in Europe and the slowing of the Chinese economy. If we think in terms of decades, then global warming, growing inequality and the disruption of the job market loom large. Yet if we take the really grand view of life, all other problems and developments are overshadowed by three interlinked processes: 1.​Science is converging on an all-encompassing dogma, which says that organisms are algorithms and life is data processing. 2.​Intelligence is decoupling from consciousness. 3.​Non-conscious but highly intelligent algorithms may soon know us better than we know ourselves. These three processes raise three key questions, which I hope will stick in your mind long after you have finished this book: 1.​Are organisms really just algorithms, and is life really just data processing? 2.​What’s more valuable – intelligence or consciousness? 3.​What will happen to society, politics and daily life when non-conscious but highly intelligent algorithms know us better than we know ourselves?

More Christians were killed by fellow Christians in those twenty-four hours than by the polytheistic Roman Empire throughout its entire existence.

The greatest crimes in modern history resulted not just from hatred and greed, but even more so from ignorance and indifference.

The current technological and scientific revolution implies not that authentic individuals and authentic realities can be manipulated by algorithms and TV cameras, but rather that authenticity is a myth. People are afraid of being trapped inside a box, but they don’t realise that they are already trapped inside a box – their brain – which is locked within a bigger box – human society with its myriad fictions. When you escape the matrix the only thing you discover is a bigger matrix. When the peasants and workers revolted against the tsar in 1917, they ended up with Stalin; and when you begin to explore the manifold ways the world manipulates you, in the end you realise that your core identity is a complex illusion created by neural networks.

...Suppose you have two free hours a week, and are uncertain whether to use them playing chess or tennis. A good friend might ask: ‘What does your heart tell you?’ ‘Well,’ you answer, ‘as far as my heart is concerned, it’s obvious tennis is better. It’s also better for my cholesterol level and blood pressure. But my fMRI scans indicate I should strengthen my left pre-frontal cortex. In my family dementia is quite common, and my uncle had it at a very early age. The latest studies indicate that a weekly game of chess can help delay its onset.’

Indeed, many movies about artificial intelligence are so divorced from scientific reality that one suspects they are just allegories of completely different concerns. Thus the 2015 movie Ex Machina seems to be about an AI expert who falls in love with a female robot only to be duped and manipulated by her. But in reality, this is not a movie about the human fear of intelligent robots. It is a movie about the male fear of intelligent women, and in particular the fear that female liberation might lead to female domination. Whenever you see a movie about an AI in which the AI is female and the scientist is male, it’s probably a movie about feminism rather than cybernetics. For why on earth would an AI have a sexual or a gender identity? Sex is a characteristic of organic multicellular beings. What can it possibly mean for a non-organic cybernetic being?
