But Harari develops ways to think about topic that are very relevant today.The 21 lessons are contained in 21 chapters, each one on a ifferent matter.
Harari takes a unique look at where artificial intelligence could take humanity, and the decisions it could make for us.
Artificial intelligence could actually analyze feelings, without having feelings itself.While discussing the role of centralized data on our system, Harari writes: Politicians are a bit like musicians, and the instrument they play on is the human motional and biochemical system.
Another theme of the books is the three threats that are above any single country 's ability to counter: nuclear war, climate change, and technological disruption.
Religions are the " handmaids of nationalism. " They make finding global solutions to our problems more difficult.
Meanwhile, nationalism and religion divide human civilization into hostile camps.The chapter on immigration is very compelling.
Harari discusses the four debates that underlie much of the arguments:1) Pro-immigrationists think that host countries have a moral duty to accept immigrants.
Host countries have worked very hard and made numerous sacrifices to build a prosperous democracy, and it 's not their fault if Syrians have failed to do the same.2) Immigrants have an obligation to assimilate.
This overreaction is a bigger dange to security than the terrorist himself.I just love these quotes: Human stupidity is one of the most important forces in history, yet wew often tend to discount it.and in the chapter on humility: Whenever they talk of God, humans all too often profess self effacement, but then use the name of God to lord it over their brethren.
Yet, in the chapter on Ignorance, Harari writes that scientists who believe that facts can change public opinion are themselves victims of scientific groupthink.
But when a billion people believe it for a thousand day, that 's called a religion.Harari sometimes goes very deep into the human psyche.
