Beyond Turing
After the body, the home. The journey of this book now enters the smallest and most decisive territory of all: the rooms in which we grow up. The Preface declared the first conviction from which everything began: the family is "the first place in which a human being discovers that he exists and that he matters". And it was born of a precise scene, a father walking a son towards the study and handing him, without knowing it, the key to a whole life. Today, in that same scene, there is almost always a third character: a screen. It sits in the father's pocket, in the son's schoolbag, on the classroom desk, on the bedside table. It is no ordinary guest: it is the first object in human history designed, with mathematical tools, to hold a child's gaze longer than the child himself would wish.
This chapter treats the screen as the book has treated every other artefact: without fear and without enchantment. It is not a chapter against technology in the home - the second conviction of the Preface remains the compass: the tool is neither worshipped nor feared; it is grasped and governed. It is a chapter about who governs, and about a truth that no app will ever change: the task of educating cannot be delegated and cannot be automated. Parents and teachers may be helped by a thousand tools; they can be replaced by none. And the reason, as always in this book, is not sentimental: it is structural, and the pages that follow demonstrate it through the five lenses of the method.
1. The screen as artefact: the engineering of attention
The first lens is the engineering one, and it asks: what, technically, is the screen that inhabits the home? Not a smaller television: an information-processing system with an optimisation objective. Herbert Simon foresaw it before the internet existed: "a wealth of information creates a poverty of attention" (Simon 1971) - and where a resource is scarce, an economy is born. The attention economy is today a mature engineering discipline, and the reader of this series will recognise its pipeline: interaction events collected as big data, preference profiles, recommendation systems that optimise a metric - dwell time, return rate, engagement. Around the metric, a repertoire of design choices that the literature knows one by one: infinite scroll, which eliminates the natural stopping point; autoplay, which turns an ending into a beginning; the notification, which converts absence into a summons; the variable reward - sometimes there is something new, sometimes not - which is the most effective reinforcement schedule that experimental psychology has ever documented (Ferster and Skinner 1957).
None of this is a conspiracy: it is optimisation, doing its job. But the chapter on work has just shown what happens when a metric becomes a target, and here the target is eight years old. A system that optimises an adult's dwell time competes with his willpower; the same system, facing a child, competes with executive functions still under construction - inhibition, impulse control, the ability to disengage - that is, with precisely what childhood has the task of developing. The European legislator has understood this and has drawn the lines: Regulation (EU) 2024/1689 prohibits systems that exploit a person's vulnerabilities due to age (Article 5); the Digital Services Act requires platforms accessible to minors to adopt reinforced protective measures and prohibits advertising based on profiling directed at them (Regulation (EU) 2022/2065, Article 28); the GDPR makes the processing of a minor's data subject to specific safeguards (Article 8). These are the right boundaries. But no regulation can do, inside the home, the job of a present adult.
2. The child: a development that cannot be accelerated
The second lens asks what is on the other side of the screen, and the answer is: a system under construction, which resembles no other user. The capacities that make a human infant a complete person - language, deep attention, the regulation of emotions, empathy - are not downloaded: they are built, in the first years, within a precise interaction that developmental science calls serve and return: the child proposes, the adult responds, the child responds to the response. It is a dialogue made of faces, pauses, glances - at very low speed and very high presence, the exact opposite of the video stream. This is why the World Health Organization recommends zero screens in the first year of life and minimal, supervised exposure until the age of five (WHO 2019): not out of moralism, but because every hour of screen, at that age, is an hour taken away from the only training ground where those capacities are trained.
On the season that follows - adolescence and social media - this book applies its rule of honour: to declare what is known and what is still contested. The scientific literature is divided on the magnitude of the effects of screens on the psychological well-being of adolescents, and whoever promises certainties in one direction or the other is simplifying. But on some points the convergence is broad: sleep eroded by evening use, time shifted away from formative activities - free play, sport, the fertile boredom from which imagination is born - and the underlying asymmetry, which nobody disputes: on one side an optimisation system trained on billions of interactions, on the other a person in formation. There is no need to demonise the screen to recognise that this is not an even match, and that someone must act as referee. That someone has an ancient name: parent.
3. The school and the teacher: knowledge transmitted through relationship
The third lens enters the classroom, where artificial intelligence has arrived with serious promises and serious questions. The promise even has a classical foundation: Benjamin Bloom showed that a student followed by a personal tutor outperforms the student in a traditional classroom by two standard deviations (Bloom 1984), and ever since, education has pursued the dream of a tutor for each. Adaptive tutors, learning analytics systems that read progress, platforms that personalise the pathway: these are real tools, and in wise hands they are precious - especially for those who start behind. European law, once again, has set the right guardrails: AI systems that decide access to education, assess students or proctor their examinations are classified as high-risk (Regulation (EU) 2024/1689, Annex III), with an obligation of human oversight; and the prohibition on emotion recognition applies in the classroom too (Article 5). The lesson of the chapter on work holds identically here: learning analytics is an excellent thermometer and a terrible target - woe to the school that optimises the dashboard instead of the student.
But the real question runs deeper than the technology, and the great traditions have guarded it for millennia: the knowledge that matters is not transferred, it is transmitted - and transmission is a relationship, not a protocol. Judaism does not entrust the Torah to an archive but to a bond, the one between master and disciple, where one learns by serving and by asking; India called its wisdom upaniṣad, which literally means to sit close by - knowledge is what happens in the nearness of one who knows; classical Islam certified knowledge with the ijāza, the licence attesting not what you have read, but with whom you have studied, in a chain of persons ascending face by face. Three civilisations, one conviction: content is the lesser part of teaching. The greater part is what the algorithmic tutor does not have: the example, the demand, the trust that precedes performance, the gaze that says "you can" to a student who does not believe it. A language model can explain Pythagoras's theorem in a hundred ways - and that is a real help. But no student, in the entire history of schooling, has ever become great because of an explanation: he became great because someone saw him.
4. The home and the rule: governing the tool, safeguarding trust
The fourth lens returns home, where the rules are written not by the legislator but by whoever lays the table. And here the book's method suggests treating the family as one treats every well-designed system: with a few clear invariants, instead of a thousand controls. The first invariant is time and place: there are spaces without screens - the table, the bedroom, the hour before sleep - not as punishment, but as architecture, in the same way that the chapter on work defended the seventh day. The second is example: no rule holds if the adult who imposes it consults his phone while his child is speaking to him - scholars have a name for this daily interference of technology in the relationship (technoference: McDaniel and Coyne 2016), and children have a simpler one: "Dad, are you listening to me?". The third is gradualness: the tool is handed over the way one hands over the keys to the house, a little at a time, together with the trust and the responsibility that make it governable.
And there is a fourth invariant, the most delicate, which welds this chapter to the one on the brain and its safekeeping: surveillance is not education. Technology offers parents a power that no generation has ever had - to locate, to read, to trace every digital step of a child - and the temptation is understandable, because it is born of love and of fear. But the book has learned, chapter after chapter, that the person in formation also has a right to an inside of his own: growing up also means having unobserved spaces in which to err, to try again, to become. The parent who watches everything is not protecting the child: he is preventing him from training exactly the freedom that one day he will have to bear alone. To keep is not to surveil: the keeper watches over the boundary and leaves the garden alive; the watchman occupies the garden and calls it security. Parental control tools are useful servants in early childhood and terrible masters in adolescence - like every technology in this book, they work only within a relationship that exceeds them.
5. The filial remainder: what no screen can give
In the end, the territory of the home too yields its remainder - and here the remainder has the most ancient face of all. Before any screen, the child looks at a screen that is not a screen: the face of the one who loves him. It is there that he learns the things no device will ever teach him: that he exists, because someone answers him; that he matters, because someone looks at him with joy; that the world is trustworthy, because someone always comes back. The screen can entertain, inform, even teach - and in this book nobody despises it. But there is one thing it cannot do, by construction and not by defect: it cannot love. It can simulate attention, and indeed it captures it; it cannot give it, because it has nothing of its own to give. To educate - the word itself says it, e-ducere - is to draw out, not to download in: it is the exact opposite of the download.
And that first screen that is not a screen - the face - does not necessarily dwell in a single house, nor in the same one throughout childhood. The writer knows this not from theory: raised first in his grandparents' house, he knew as a child the loss of those who watched over him, and spent his school years in a boarding institute, far from home, until university in a city in the north. And yet the lesson of this chapter was fulfilled all the same, and in two ways. There were, at every stage, nearby faces that watched: a grandmother, an educator, a teacher. And there were, always, two distant faces that never ceased to follow: a mother and a father who accompanied him from afar, with his father's voice repeating - study, be careful - and lighting up with pride at every result. That encouragement was his strength then and is his strength now, when those two voices are gone: it is the truth the Preface delivered with its first conviction, and which here finds its story - affection at a distance loses nothing of its light. The home, the book can say it with the authority of experience, is not an address: it is wherever someone looks at a child the way one looks at a promise - from near or from far, it does not matter, because love bridges every distance that the screen can only shorten. And no childhood is poor in family as long as it is rich in faces that respond; none is rich in faces if the ones present are looking elsewhere.
This is why the last word of the chapter concerns not the children, but the adults. The child's screen is governed by rules; the parent's screen is governed by a question, to be asked every evening: what did my child look at today - and who looked at him? A childhood has no reruns: it airs once only, live, and its hours do not return. A screen can be switched off and on again; a childhood cannot. And so the most technologically advanced gesture an adult can perform, in a house full of intelligent devices, remains the one from the scene where this book was born: walking a child towards the study, handing him a key, and watching him - with the phone switched off - as he opens the door. No algorithm will ever be able to do this. Not because it is not yet powerful enough: because this is not a task. It is a love. And love, as the reader by now knows, dwells in the incalculable remainder.
