Imagine a situation—in twenty years, say—when somebody in Beijing or San Francisco possesses the entire personal history of every politician, journalist, colonel, and CEO in your country: every text they ever sent, every web search they ever made, every illness they suffered, every sexual encounter they enjoyed, every joke they told, every bribe they took. Would you still be living in an independent country, or would you now be living in a data colony? What happens when your country finds itself utterly dependent on digital infrastructures and AI-powered systems over which it has no effective control?

Such a situation can lead to a new kind of data colonialism in which control of data is used to dominate faraway colonies. Mastery of AI and data could also give the new empires control of people’s attention. As we have already discussed, in the 2010s American social media giants like Facebook and YouTube upended the politics of distant countries like Myanmar and Brazil in pursuit of profit. Future digital empires may do something similar for political interests.

Drinking lots of will not make you young, will not make you healthy, and will not make you athletic – rather, it increases your chances of suffering from obesity and diabetes. Yet for decades Coca-Cola has invested billions of dollars in linking itself to youth, health and sports – and billions of humans subconsciously believe in this linkage.

During the Cold War, the Iron Curtain was in many places literally made of metal: barbed wire separated one country from another. Now the world is increasingly divided by the Silicon Curtain. The Silicon Curtain is made of code, and it passes through every smartphone, computer, and server in the world. The code on your smartphone determines on which side of the Silicon Curtain you live, which algorithms run your life, who controls your attention, and where your data flows.

It is becoming difficult to access information across the Silicon Curtain, say between China and the United States, or between Russia and the EU. Moreover, the two sides are increasingly run on different digital networks, using different computer codes. Each sphere obeys different regulations and serves different purposes.

The typical scientist doesn’t actually practise meditation herself. Rather, she invites experienced meditators to her laboratory, covers their heads with electrodes, asks them to meditate, and observes the resulting brain activities. That can teach us many interesting things about the brain, but if the aim is to understand the mind, we are missing some of the most important insights.

Can you name a great work of art inspired by the Old Testament? Oh, that's easy: Michelangelo's David, Verdi's Nabucco, Cecil B. DeMille's The Ten Commandments. Do you know of any famous work inspired by the New Testament? Piece of cake: Leonardo's Last Supper, Bach's St. Matthew Passion, Monty Python's Life of Brian. Now for the real test: can you list a few masterpieces inspired by the Talmud?Though Jewish communities that studied the Talmud spread over large parts of the world, they did not play an important role in the building of the Chinese empires, in the European voyages of discovery, in the establishment of the democratic system, or in the Industrial Revolution. The coin, the university, parliament, the bank, the compass, the printing press, and the steam engine were all invented by Gentiles.

One would have thought that conservatives would care far more about the conservation of the old ecological order, and about protecting their ancestral lands, forests and rivers. In contrast, progressives could be expected to be far more open to radical changes to the countryside, especially if the aim is to speed up progress and increase the human standard of living. However, once the party line has been set on these issues by various historical quirks, it has become second nature for conservatives to dismiss concerns about polluted rivers and disappearing birds, while left-wing progressives tend to fear any disruption to the old ecological order.

So at twenty-five you introduce yourself on a dating site as ‘a twenty-five-year-old heterosexual woman who lives in London and works in a fashion shop’. At thirty-five you say you are ‘a gender-non-specific person undergoing age-adjustment, whose neocortical activity takes place mainly in the NewCosmos virtual world, and whose life mission is to go where no fashion designer has gone before’.

Many pedagogical experts argue that schools should switch to teaching ‘the four Cs’ – critical thinking, communication, collaboration and creativity.3 More broadly, schools should downplay technical skills and emphasise general-purpose life skills. Most important of all will be the ability to deal with change, to learn new things, and to preserve your mental balance in unfamiliar situations.

If we are willing to make such efforts in order to understand foreign cultures, unknown species and distant planets, it might be worth working just as hard in order to understand our own minds. And we had better understand our minds before the algorithms make our minds up for us.

The most important secular commitment is to the truth, which is based on observation and evidence rather than on mere faith. Seculars strive not to confuse truth with belief.

Leaders are thus trapped in a double bind. If they stay in the centre of power, they will have an extremely distorted vision of the world. If they venture to the margins, they will waste too much of their precious time. And the problem will only get worse. In the coming decades, the world will become even more complex than it is today. Individual humans – whether pawns or kings – will consequently know even less about the technological gadgets, the economic currents, and the political dynamics that shape the world. As Socrates observed more than 2,000 years ago, the best we can do under such conditions is to acknowledge our own individual ignorance.

Humans are organic beings who live by cyclical biological time. ... Even the money market respects these biological cycles. The New York Stock Exchange is open Monday to Friday, from 9:30 in the morning to 4:00 in the afternoon, and is closed on holidays like Independence Day and New Year’s Day. If a war erupts at 4:01 p.m. on a Friday, the market won’t react to it until Monday morning.

In contrast, a network of computers can always be on. Computers are consequently pushing humans toward a new kind of existence in which we are always connected and always monitored. In some contexts, like health care, this could be a boon. In other contexts, like for citizens of totalitarian states, this could be a disaster. Even if the network is potentially benign, the very fact that it is always on might be damaging to organic entities like humans, because it will take away our opportunities to disconnect and relax. If an organism never has a chance to rest, it eventually collapses and dies. But how will we get a relentless network to slow down and allow us some breaks?
