A conceptual editorial illustration depicting the transition from a linear career path to a world of navigation. A sleek, corporate staircase made of polished white stone rises out of a deep, turbulent ocean. The staircase is perfectly linear and rigid, but its top steps are fractured and lead into an empty, vast sky. On the surface of the water below, a lone, sturdy wooden boat sails through the shifting waves. The lighting is dramatic, with a storm clearing to reveal a bright, open horizon. The style is clean, modern, and symbolic, representing the transition from predictable structures to a life of navigation and agency.

The World That Stopped Being Linear

I’m writing Agency Is All You Need in public — every chapter ships as an essay, gets argued with by readers, then revised into the final book (Q1 2027).

Read the series introduction.

Sonja is looking for her tax folder when the brochure surfaces: Your Path With Us, the onboarding booklet from 2015, glossy, slightly curled at one corner. On the cover, a stock-photo staircase in corporate blue. Inside, the diagram she once photographed and sent to her mother: five boxes connected by confident arrows. Trainee → Specialist → Senior Specialist → Team Lead, Claims Steering → Head of Department. Under the last box, someone in HR had allowed themselves a flourish: …and beyond.

Sonja is in her mid-thirties, studied insurance economics, and has spent ten years doing everything right at a large insurer. Box one: done, 2016, with distinction. Box two: 2018. Box three: 2021, ahead of schedule. By the diagram’s own logic she is due for box four within eighteen months. She opens the restructuring memo’s annex — she keeps it locally now, like a weather chart — and lays the two documents side by side.

Box four: the annex lists claims steering among functions to be “consolidated under the automated claims platform.” The team she would have led is scheduled to shrink from twelve to five. Box five: the department itself appears in a footnote, in the past tense of org charts — merged into Regional Operations Hub West.

Three of her five boxes still exist. The two she was climbing toward do not. Nobody lied to her. In 2015, every arrow in the diagram was true — the way a train schedule is true until the line is closed.

She doesn’t throw the brochure away. She files it in the tax folder, as what it now is: a historical document.

The script

Everyone in Sonja’s world carries some version of that diagram, usually without knowing where they got it. Call it the linear life script: the assumption that a life unfolds as steady, predictable progress through a fixed sequence — education, then job, then career, then retirement. Each stage prepares the next; effort in one buys entry to the next; and — this is the load-bearing assumption — the whole thing is legible in advance. You can see the staircase from the bottom.

The script was never written down as a rule. It was built into everything, which is stronger. It’s in the question adults ask children (“what do you want to be?” — one thing, chosen once). It’s in the CV format, which renders a life as an unbroken ascending column and makes every gap a confession. It’s in mortgage underwriting, pension design, and parental pride.

Here is the claim of this essay: the script was not the natural shape of a working life. It was a historical anomaly — a construction of roughly 1950 to 2010, in wealthy countries, for the formally employed within them — that lasted just long enough to be mistaken for nature.

Consider what had to be true, all at once, for the staircase to exist. Economies had to grow steadily enough that large organizations could promise decades-long employment. Firms had to be big, hierarchical, and stable enough to contain entire careers, with internal ladders and personnel departments that planned your development the way logistics planned inventory. Knowledge had to change slowly enough that what you learned by twenty-five would carry you to sixty-five — education as a phase, completed and certified once, rather than a practice. And states had to underwrite the whole arc with pensions and protections keyed to continuous formal employment.

Every one of those conditions was historically unusual, and every one was local. For most of human history, and in most of the world throughout this entire period, working life was not a staircase. It was navigation — seasonal, improvised, multi-stranded, kin-based. The linear script was a seventy-year exception experienced by a minority of the world’s population, who happened to write nearly all of the career advice.

Two things about the exception deserve respect before we watch it end. First, it delivered real goods: security, dignity, the ability to promise a child that effort converts into stability. Sonja’s father worked forty-one years at the same utility company; there is a certificate for it in the hallway of her parents’ house, and it is a monument to something real. Second, the script had a shadow its beneficiaries rarely priced in: it answered what next? on your behalf so completely that the muscle for answering it yourself was allowed to atrophy.

What the machines actually change

The script began fraying before any current technology cycle — globalization, delayering, and the steady shift of risk from institutions to individuals were cutting at it through the 1990s and 2000s. What AI does is different in kind: it doesn’t merely stress the staircase. It dismantles the building the staircase was in. Strip away both the hype and the counter-hype, and it does three specific things to knowledge work.

It unbundles the career package. A stable profession was always a bundle: a body of knowledge, a network of peers, and a credential that certified you to strangers — acquired together, over years, at one price. As I traced in Education is Broken, these components are coming apart: knowledge is now abundant and nearly free, networks form outside institutions, and credentials are decoupling from competence. When the knowledge component of an occupation becomes cheaply available to anyone — or to a machine — the remaining value concentrates in what can’t be unbundled: judgment, trust, accountability, taste, the network that vouches for you. The bundle Sonja bought with her degree has been repriced, component by component, while the diploma on her wall stays the same.

It shortens the half-life of skills. Treat any specific skill as a decaying asset: from the day you acquire it, its value erodes as tools change and supply catches up. Under the script, the decay was slow enough to ignore — one education could amortize over forty years. The circulating estimates of today’s skill half-life vary too much to print, but the direction is beyond dispute, and Sonja can verify it from her own desk: reserving techniques she mastered in 2019 are now a button in software. When skills decay faster than careers last, learning stops being a life phase and becomes a permanent practice.

It automates the middle before the edges. The popular imagination assumed machines would climb from the bottom: first the warehouse, then the office, someday the professions. Current AI inverts the sequence. What it does best is precisely the structured cognitive work of the professional middle — summarizing, drafting, classifying, reconciling, first-pass analysis. And “the middle” is not only a task description; it is an org-chart location. A significant share of middle management exists to move information up and instructions down. Software that does this natively doesn’t just eliminate tasks — it thins the very layer that career ladders climb through. Fewer rungs, spaced further apart, more claimants per rung: that is the annex on Sonja’s screen, described structurally.

There’s a second-order effect worth pausing on. When automation eats the routine bottom of a profession — the claims files, the standard analyses, the support work where juniors used to become seniors — it also eats the traditional path into the profession’s top. The credentialed judgment at the top remains; the apprenticeship beneath it hollows out. The ladder loses its lower rungs even where the upper ones survive.

None of this means work disappears; every previous automation wave created new work, and this one already visibly does. It means something more personal: the sequence disappears. What is being automated away is not employment. It is predictability.

And here is what makes Sonja’s case instructive rather than merely sad: by every metric the script recognizes, she did everything right. Right degree, right employer, right program, right mentor. Her predicament is not a performance failure, and no performance would have prevented it. The script itself — the meta-promise that doing everything right produces a foreseeable next — is what failed. If you take one sentence from this essay, take that one, because it dissolves both wrong responses at once: shame (I must have failed) and paralysis (someone must fix this before I can move). Nobody failed, and nobody is coming to re-lay the track.

The man who never had a script

Now look at the same world through different eyes, and notice that the catastrophe described above has a strange property: you can only lose the script if you ever had it.

Abdellatif came to Germany from Morocco. His father worked, over the years, as an electrician’s mate, a market trader, a building caretaker, and several things between — not as failure, but as the normal texture of working life in Casablanca. His mother came from Somalia and built a household that functioned across two languages and an informal economy. His siblings in Morocco hold ordinary jobs, and every one of those working lives has been navigated rather than scheduled: multiple income strands, family as employment agency and insurance fund, plans held lightly because weather changes. When Abdellatif took apart his first fuse box at fourteen, no brochure showed him five boxes and an arrow. The question was never what is my path? It was always what works, this season, from here?

So when the ground shifts under the formally employed of Cologne and Munich, his world registers it differently. He is not losing a promise; no institution ever made him one. He met the script mostly as an obstacle course — a society that files people by credential and continuous employment history, neither of which his life was shaped to produce.

This inversion matters, for two reasons. First, it locates the script correctly: as a local privilege, not a human default. The post-linear world that frightens the credentialed middle of wealthy countries is, structurally, a return toward the world’s normal condition — now with better tools and, for some, better buffers. Sonja’s coming decade will demand skills that Abdellatif’s family has practiced for generations: sensing, improvising, keeping several strands alive, treating plans as provisional.

Second, it keeps the reframe honest. It would be too neat to say Abdellatif is the future and Sonja the past — the migrant as parable is its own kind of condescension. He has navigation experience she lacks; she has institutional room he lacks; the divide between them is not talent but inheritance, and the new world does not erase it. What his counterpoint establishes is narrower and more useful: a life without the script is not an unlivable life. It is the most common kind of life there has ever been. The staircase people are not falling into a void. They are joining everyone else.

Loss and release

What replaces the script? Not a new script — that’s the first reflex to retire. The templates on offer (“everyone will have seven careers,” “everyone must become a founder,” learn-to-code and whatever replaced it) are staircase thinking with new paint: someone else’s sequence, adopted whole. What actually replaces the script is a different posture: a heading instead of a path, revised as you sense and respond; several strands and open options instead of one ascending line; buffers you can count instead of promised security; learning as a practice instead of a completed phase. None of it requires heroism. All of it can be practiced. Building that posture is what this book — and this essay series — is for.

But end on the two truths together, because the temptation to drop one of them is constant.

The end of the linear script is a genuine loss. Predictability was not a bourgeois illusion; it was infrastructure for ordinary courage — people started families, bought homes, and slept at night on it. Mourning it is not weakness, and anyone selling the new world as pure liberation has nothing at stake.

And the end of the script is a genuine release. The staircase told you what to want. It filed lives into five boxes and called deviation failure, and it made obedience feel like prudence. Sonja would not have chosen this rupture — and yet, somewhere under the fear, there is a sensation she hasn’t named yet: for the first time since she photographed that diagram for her mother, the question what do I actually want the next ten years to be? is genuinely open, and genuinely hers.

On Sunday, on the phone, it is Abdellatif’s brother in Izmir — a man who never saw a staircase he was allowed to climb — who says the sentence this essay ends on:

“There is no route, habibi. There never was. There is only the boat, and the weather, and how you sail.”


Sonja and Abdellatif are constructed figures — personas built to carry real mechanisms, not case studies of real persons.
