When a city in the United States plans a new rail line, it calculates with time. Every minute passengers will no longer spend traveling is translated into dollars. The basis is guidance from the US Department of Transportation. It values each saved hour as a share of the travelers' hourly income. Planners in Europe work with similar methods.

That sounds technical. Behind it lies one of the most consequential assumptions of our time: a person's hour is worth what someone pays for it.

I asked myself what this calculation says about a person who no longer earns a wage. The answer is uncomfortably simple. In it, that person's hour is worth almost nothing. Not because the hour is empty. The formula simply knows no other yardstick.

Before the Wave

I do not want to dramatize anything. The great waves of layoffs driven by artificial intelligence have not arrived yet. In US labor market data, the effect still accounts for less than one percent of all layoffs.

Still, the direction is visible. By September 2026, companies in the United States had cited AI for more than 120,000 announced job cuts. That was one in five cuts this year. Goldman Sachs estimates that around nine percent of workers could be displaced over the course of a decade. According to this analysis, it happens mainly when the economy weakens.

Yardsticks are not made in a crisis. Anyone who waits until after the wave to ask what a free hour is worth will keep measuring with the old formula. That is why the question belongs on the table now, while there is still time to answer it calmly.

What Work Gave on the Side

Work has always delivered more than money. It gave the day a shape. It brought together people who would otherwise never have met. It gave a reason to get up in the morning. It conferred a standing that no one had to explain. Research on unemployment and retirement shows how much of this is lost when work ends. That holds even when income continues.

Where do the hours without a price go? The American Time Use Survey for 2025 counts a little over five hours of leisure a day. People spend half of it in front of the television. On average, they read for sixteen minutes. The share of people who spend any time with others at all has fallen markedly.

I do not read this as a reproach to people. I read it as a shortage of places. An hour that has nowhere to go ends up where it meets the least resistance. That is a question of infrastructure, not of character.

A Different Measure

If wages fail as a yardstick, we need a new one. The attempt is not new. The economist Alan Krueger and the psychologist Daniel Kahneman proposed almost twenty years ago to measure a society's well-being by its time. They asked how people feel during their activities. That was a big step.

But a pleasant evening in front of a screen can feel better than a strenuous day on a riverbank planting willows. Feeling measures the moment. It does not measure what remains.

That is why we are developing the Human Time Index. It asks about five qualities of an hour. Was it chosen, or did someone else fill it? Did attention stay whole? With whom was it shared? Did it leave a trace, a skill, a work, a person who is better off? How far into the future does the purpose reach for which it was spent? Others have asked the first three questions before. Trace and horizon are what we add. A society whose free hours reach further ahead will also think further ahead.

If you want to check your own week against it, you can do so here: After Work: Human Time When Machines Do the Jobs. The self-test takes a few minutes. It does not show how much free time you have. It shows how much of it carries weight.

A measure alone fills no hour, however. That takes places, tasks and recognition. And this is not only about people whose work a machine has taken over. A fifteen-year-old girl, whom no future profession promises that she will be needed, is looking for the same answer. A couple in their early thirties who are just starting a family are looking for it too. The ideas I present here for the first time begin in the neighborhood and end on another planet.

The Hour Without an Exchange Rate

A Tuesday in an apartment building. In the morning, a mother in her mid-thirties drives her elderly neighbor to the doctor. Her toddler sleeps in the back seat. In the afternoon, a man in his early sixties, formerly a dispatcher at a freight company, reads to her older son. In the evening, a sixteen-year-old from the third floor repairs his bike trailer. Nobody pays anybody. Every one of these hours is recorded all the same. An hour of reading aloud counts exactly as much as an hour spent on the bike trailer. For the sixteen-year-old, it is the first recognition of her life that does not come as a school grade.

Japan has had this principle since 1995. It is called Fureai Kippu, roughly "ticket for a caring relationship." Anyone who helps older people receives time credits. They can save them for their own old age. They can also transfer them to their parents in another city, so that someone there looks after them.

One finding from Japan has stayed with me. Older people preferred helpers who worked for time over those paid in yen. The reason lay in the nature of the relationship. Most helpers, moreover, had no intention of ever redeeming their credits.

The system has its difficulties. After 2000 it lost momentum. It is no cure-all. But it proves something fundamental: an hour can have value without having a price.

After work, this idea would no longer be confined to care. Every hour given to others would become visible. It would be exchanged not for money but for recognition. The credit would be less a means of payment than a record. It says: here, someone counted for others.

The Observer's Hour

What we give one another is a beginning. The next question is what we can give the planet.

Around 1900, it was a custom in parts of the United States to compete on Christmas Day at shooting birds. Conservationists proposed counting the birds instead. That switch became the oldest citizen census in the world. In its 125th edition, more than 83,000 volunteers counted at nearly 2,700 locations between Canada and the Caribbean. Their data show researchers how bird populations change over a century.

I take this story as a parable. It was the same free time, the same joy in being outdoors. Only the direction changed, from consuming to measuring.

Since 2016 there has been a small device based on a Raspberry Pi that records movements of the ground. Thousands of people have set it up in basements, schools and gardens. The result is the largest citizen-run earthquake network in the world. Its data now help locate earthquakes in New Zealand more precisely. In El Salvador, they help monitor volcanoes.

Let us imagine a morning after work. A woman, formerly a bookkeeper, starts her day in the garden. She reads the rain gauge. She checks her seismometer. In the evening she counts the bats over the pond with her granddaughter. A few streets away, a man in his late twenties looks after the measuring point at a spring. For a long time he did not know what to do with himself. Through his data he got talking with a hydrologist. One hour a week has become a direction. Their measurements flow into a network that brings millions of such hours together. No satellite sees what these people see.

What it would take is manageable. Every library could lend measuring devices the way it lends books. Research institutes could train citizens instead of merely collecting their data. Every measurement would carry the name of the person who made it. A planet observed by millions of people is better understood than one surveyed only by satellites and specialists. The people who observe it understand it better too.

The Expedition Year

Whoever has learned to look closely at the Earth will at some point ask another question. What would it be like to live somewhere else?

The Austrian Space Forum is a largely volunteer-run association. For years it has sent crews into deserts that resemble Mars: to Oman, to Israel's Negev, most recently in 2024 to Armenia. More than 200 researchers from over 25 countries work on such a mission. The crews themselves, however, are highly qualified specialists with months of training. A year at such a station is today a privilege of the few.

After work, it could become a stage in the lives of many. A year at a place that anticipates life on another world: in the desert, in the Arctic, under a dome. Participants grow plants in closed loops. They repair suits with limited tools. They record how people get along in tight quarters. Each crew hands its knowledge on to the next.

A crew of six lives in such a station. The oldest is in his mid-fifties. A robot now does his old workshop job. He knows how to keep a pump running when the spare part is missing. The youngest is nineteen. After school she did not know what to do with herself. After three months she repairs the pump on her own. The crew also includes a doctor in her early thirties. She chose her expedition year before starting a family. When the crew returns, each of them has done something that could still count in a hundred years. The year sits in their résumés as naturally as a university degree.

Carrying life to other worlds will not remain the task of a small number of astronauts. It needs the experience of a great many people, gathered over generations. Free hours are the one resource that arises in sufficient quantity for this.

How Far an Hour Reaches

The formula from transport planning will not disappear on its own. It will become superfluous only when we can show what an hour is worth otherwise.

The answer does not lie in a new price. It lies in the reach of what an hour is spent on. An hour for a neighbor reaches the next door. An hour at the seismometer reaches around the whole planet. A year at a station reaches a world that no one inhabits yet.

For centuries, work told people that they were needed. After work, we have to learn to say this in a new way. I believe it can become a more joyful way of saying it than the old one.

These ideas are a beginning. Which idea for a life after work is still missing? Share it in the comments. The strongest ones will be developed further.
