Perhaps in the twenty-first century populist revolts will be staged not against an economic elite that exploits people but against an economic elite that does not need them anymore.6 This may well be a losing battle. It is much harder to struggle against irrelevance than against exploitation.

This reliance on the heart might prove to be the Achilles’ heel of liberal democracy. For once somebody (whether in Beijing or in San Francisco) gains the technological ability to hack and manipulate the human heart, democratic politics will mutate into an emotional puppet show.

In 1938 humans were offered three global stories to choose from, in 1968 just two, and in 1998 a single story seemed to prevail. In 2018 we are down to zero.

The merger of infotech and biotech might soon push billions of humans out of the job market and undermine both liberty and equality. Big Data algorithms might create digital dictatorships in which all power is concentrated in the hands of a tiny elite while most people suffer not from exploitation but from something far worse—irrelevance.

Democracy is based on Abraham Lincoln’s principle that “you can fool all the people some of the time, and some people all of the time, but you cannot fool all the people all the time.”

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.

Humans think in stories rather than in facts, numbers, or equations, and the simpler the story, the better.

But liberalism has no obvious answers to the biggest problems we face: ecological collapse and technological disruption.

Humans were always far better at inventing tools than using them wisely.

Two particularly important nonhuman abilities that AI possesses are connectivity and updatability.

It is debatable whether it is better to provide people with universal basic income (the capitalist paradise) or universal basic services (the communist paradise). Both options have advantages and drawbacks. But no matter which paradise you choose, the real problem is in defining what “universal” and “basic” actually mean.

Human power depends on mass cooperation, and mass cooperation depends on manufacturing mass identities—and all mass identities are based on fictional stories, not on scientific facts or even on economic necessities.

So if you want to know the truth about the universe, about the meaning of life, and about your own identity, the best place to start is by observing suffering and exploring what it is. The answer isn’t a story.

Potential solutions fall into three main categories: what to do in order to prevent jobs from being lost; what to do in order to create enough new jobs; and what to do if, despite our best efforts, job losses significantly outstrip job creation.

When a thousand people believe some made-up story for one month, that’s fake news. When a billion people believe it for a thousand years, that’s a religion, and we are admonished not to call it “fake news” in order not to hurt the feelings of the faithful (or incur their wrath).

Questions you cannot answer are usually far better for you than answers you cannot question.

If we want to prevent the concentration of all wealth and power in the hands of a small elite, the key is to regulate the ownership of data.

The danger is that if we invest too much in developing AI and too little in developing human consciousness, the very sophisticated artificial intelligence of computers might only serve to empower the natural stupidity of humans.

People still have different religions and national identities. But when it comes to the practical stuff—how to build a state, an economy, a hospital, or a bomb—almost all of us belong to the same civilization.

So in the twenty-first century religions don’t bring rain, they don’t cure illnesses, they don’t build bombs—but they do get to determine who are “us” and who are “them,” whom we should cure and whom we should bomb.
