21 Lessons for the 21st Century(20)

In some countries and in some situations, people might not be given any choice, and they will be forced to obey the decisions of Big Data algorithms. Yet even in allegedly free societies, algorithms might gain authority because we will learn from experience to trust them on more and more issues, and will gradually lose our ability to make decisions for ourselves. Just think of the way that within a mere two decades, billions of people have come to entrust the Google search algorithm with one of the most important tasks of all: searching for relevant and trustworthy information. We no longer search for information. Instead, we google. And as we increasingly rely on Google for answers, so our ability to search for information by ourselves diminishes. Already today, ‘truth’ is defined by the top results of the Google search.11

This has also been happening with physical abilities, such as navigating space. People ask Google to guide them around. When they reach an intersection, their gut feeling might tell them ‘turn left’, but Google Maps says ‘turn right’. At first they listen to their gut feeling, turn left, get stuck in a traffic jam, and miss an important meeting. Next time they listen to Google, turn right, and make it on time. They learn from experience to trust Google. Within a year or two, they blindly rely on whatever Google Maps tells them, and if the smartphone fails, they are completely clueless. In March 2012 three Japanese tourists in Australia decided to take a day trip to a small offshore island, and drove their car straight into the Pacific Ocean. The driver, twenty-one-year-old Yuzu Nuda, later said that she just followed the instructions of the GPS and ‘it told us we could drive down there. It kept saying it would navigate us to a road. We got stuck.’12 In several similar incidents people drove into a lake, or fell off a demolished bridge, by apparently following GPS instructions.13 The ability to navigate is like a muscle – use it or lose it.14 The same is true for the ability to choose spouses or professions.

Every year millions of youngsters need to decide what to study at university. This is a very important and very difficult decision. You are under pressure from your parents, your friends and your teachers, who have different interests and opinions. You also have your own fears and fantasies to deal with. Your judgement is clouded and manipulated by Hollywood blockbusters, trashy novels, and sophisticated advertising campaigns. It is particularly difficult to make a wise decision because you do not really know what it takes to succeed in different professions, and you don’t necessarily have a realistic image of your own strengths and weaknesses. What does it take to succeed as a lawyer? How do I perform under pressure? Am I a good team-worker?

One student might start law school because she has an inaccurate image of her own skills, and an even more distorted view of what being a lawyer actually involves (you don’t get to give dramatic speeches and shout ‘Objection, Your Honour!’ all day). Meanwhile her friend decides to fulfil a childhood dream and study professional ballet dancing, even though she doesn’t have the necessary bone structure or discipline. Years later, both deeply regret their choices. In the future we could rely on Google to make such decisions for us. Google could tell me that I would be wasting my time in law school or in ballet school – but that I might make an excellent (and very happy) psychologist or plumber.15

Once AI makes better decisions than us about careers and perhaps even relationships, our concept of humanity and of life will have to change. Humans are used to thinking about life as a drama of decision-making. Liberal democracy and free-market capitalism see the individual as an autonomous agent constantly making choices about the world. Works of art – be they Shakespeare plays, Jane Austen novels, or tacky Hollywood comedies – usually revolve around the hero having to make some particularly crucial decision. To be or not to be? To listen to my wife and kill King Duncan, or listen to my conscience and spare him? To marry Mr Collins or Mr Darcy? Christian and Muslim theology similarly focus on the drama of decision-making, arguing that everlasting salvation or damnation depends on making the right choice.

What will happen to this view of life as we increasingly rely on AI to make decisions for us? At present we trust Netflix to recommend movies, and Google Maps to choose whether to turn right or left. But once we begin to count on AI to decide what to study, where to work, and who to marry, human life will cease to be a drama of decision-making. Democratic elections and free markets will make little sense. So would most religions and works of art. Imagine Anna Karenina taking out her smartphone and asking the Facebook algorithm whether she should stay married to Karenin or elope with the dashing Count Vronsky. Or imagine your favourite Shakespeare play with all the crucial decisions taken by the Google algorithm. Hamlet and Macbeth will have much more comfortable lives, but what kind of life will it be exactly? Do we have models for making sense of such a life?

As authority shifts from humans to algorithms, we may no longer see the world as the playground of autonomous individuals struggling to make the right choices. Instead, we might perceive the entire universe as a flow of data, see organisms as little more than biochemical algorithms, and believe that humanity’s cosmic vocation is to create an all-encompassing data-processing system – and then merge into it. Already today we are becoming tiny chips inside a giant data-processing system that nobody really understands. Every day I absorb countless data bits through emails, tweets and articles; process the data; and transmit back new bits through more emails, tweets and articles. I don’t really know where I fit into the great scheme of things, and how my bits of data connect with the bits produced by billions of other humans and computers. I don’t have time to find out, because I am too busy answering all these emails.
