Stop selling your time by the slice

Since the Industrial Revolution, we humans have come, without quite noticing, to treat an absurdly simplified economic principle as unquestionable truth: Time is Money. A system that converts every tick of the clock into monetary value was a remarkable invention, and it did accelerate civilization, at least in form. But it also laid an irreversible curse on our minds. The value of work, one of the most human of all activities, came to be measured by a single physical yardstick, the length of time spent, and this crude, low-resolution standard now covers the whole world. Because this is how we got to where we are, it is the problem we of the modern age most need to face honestly.

The damage this system has done is enormous. The essence of work has been ruthlessly thinned out, hollowed into the selling of time by the slice. Against it, we now hear a good deal about work-life balance, about how "life is not for working." I understand that as a bodily recoil from the excessive worship of labor. But I cannot help feeling that this current, too, is dangerous. It leaves untouched the false premise that work and labor are the same thing. If we keep work reduced to labor, treat it as drudgery, and make escape from it the aim of life, then we will have to spend most of our waking hours as if we were dead. Which is to say, we will spend our lives as if we were dead.

Work, for a human being, was never meant to fit inside the frame of wage labor. It is a profoundly existential act: you project your own life energy into the outside world and leave a physical trace there. Work is the only means we have of standing against the unavoidable fact of flowing time, and it carries an intensity that leisure, which is only consumption, cannot come near.

The greatest problem with our present social system is this. It is comfortable for people who produce nothing, or who do not burn their lives to make something. For people who try to create by burning their own inner heat, it is far too harsh.

Suppose a master of some field, after thirty years of grueling training, uses the latest technology to finish a difficult job in five minutes. Passed through the filter of today's market, the result is treated as five minutes of labor and given a very cheap price tag. What ought to be valued is the thirty years that lie behind those five minutes, and more than that, the thinking that went on without a break, every day and every hour of those years. Modern capitalism has no sensor and no scale for the depth of time. It is easy to dismiss this as plain exploitation, since history offers precedents for that charge. I see it as something else: a system error at the level of civilization, a lack of resolution in our perception.

In other words, modern society can measure only the length of time. It has no way of thinking that takes in the depth and density of time as a whole. And so the world has filled up with thin products (content) that merely keep up appearances. People stretch their time thin and sell it in slices, cut their lives into pieces and cash them in, then spend the proceeds on equally thin entertainment. Their lives are used up in this thin loop in which nothing happens. A system like this, and a population of this size caught in it, has never existed before in human history.

There is a further irony. Medical progress has done one thing above all: it has stretched the biological lifespan out of all proportion. A life that once ended in the sixties on average is now forced to run to eighty or ninety. But the extra years come without the heat of actually living, and the debate over longevity does not take this into account. That the heart keeps beating and the lungs keep breathing for decades longer is nothing to celebrate. It is a grim picture of the future. And that future is already here, in Japan.

In 2025 Japan became the first super-aged society in the world. Look around any Japanese town and you will see old people everywhere, their attention unfocused, unsure what they exist for or where they are heading, wandering alone on unsteady legs. Or rather, this scene is now simply what daily life in Japan looks like. And they share one thing. They were the vanguard who kept selling their time to build the great system of rapid economic growth. They are the people who made this future, which is now our present. Sadly, they cannot deny this present, because they built it themselves, and they too are made to live, stretched thin, through a grim and extended span of time.

So they reached the vast emptiness of old age, the price they were paid for founding that system, and spent their sixties at a loss, not knowing what to do. In their seventies, eighties and nineties, unable to bear time that goes on endlessly like a life-support machine, they drift in a haze. It is a tragic ending brought on by adapting too well to the system, yet it is a fact we cannot overlook as a "success story of modernization." That is exactly why we must change the way we think. Just as the future they built is our present, what we are building now can only be worse.

We who live in their future must face this: a society whose structure does nothing but consume and squander time, a scarce resource. By simply speeding up this thin loop, we spread the lie that we are making progress, and so the whole of humanity goes on evading responsibility. Over a few years the change may look slight. But when we reach their age, it is not hard to imagine a scene even more hopeless than today's. The ascetic idea of sacrificing the present for the future is stale, but the deeper trouble is that the very notion of "the future" we assume is far too coarse in resolution.

Seen from here, I welcome AI as a powerful other. AI far surpasses us in the amount of information it can process per unit of time, and it is pushing us out of the barren contest of processing within time. I put no trust at all in the existing humanist point of view that talks of saving humanity or of thinking about the greater number. To me, the spread of AI is an opportunity to welcome. The age in which humans competed on raw processing speed or on the hours they put in is already over. To survive what comes, we have to change the ground we fight on altogether. We must step down from the horizontal competition of a linear world, where only the length of time counts, and displace ourselves to a place that integrates the vertical dimension, the density and depth of time.

The counter-concept I want to offer here is a sophisticated technique that lies deep in Japanese wisdom: sekiso (積層), layering.

In the cultures of Japan there has long been a nonlinear way of thinking in which time is not only a line running from past to future but also something that piles up thinly in the vertical direction, like strata in the earth. The most refined physical embodiment of that thought is the craft of urushi (漆), lacquer.

Lacquerwork entered daily life more than ten thousand years ago, in Japan's Jomon period. The oldest trace was found at Jomon sites around the Mikata Five Lakes in Fukui Prefecture, on the Sea of Japan coast. I went to see the actual objects this year. As archaeological evidence of lacquer technology, it is for now the oldest in the world. My own theory is that a distinctive concept of time, formed through this technology, lies at the base of the Japanese people.

Lacquerwork goes beyond what we usually call traditional craft. It is the oldest and the strongest layering technique in the world, made from a natural resin. You brush on a film of sap thinner than 0.01 millimeter, control the humidity so that it cures, polish it down with charcoal, and brush on another. A piece of lacquerware exists because this process is repeated dozens, even hundreds, of times. The interesting thing is that the finished surface does not show you the vast hours of handwork behind it. Yet time is there, physically compressed and sealed in as layer upon layer. I do not believe anything proves the nonlinearity of time as well as lacquerware does.

Anyone who has seen the finest lacquerware, with its deep, drawing-in black and its wet, particular luster, will not think of it as a mere craft object. That black is not the color of a pigment applied to the surface. It rises from the very bottom of the clear, transparent layers, a poignant trace of reality in which the origin that is Japan itself was condensed and life was slowly soaked in. That output is time's layering made visible. When time is piled up vertically it becomes nonlinear, and the material gains an overwhelming resistance to time and a deep beauty.

Japanese also has the phrase "to put one's heart into" (kokoro wo komeru). Today it has been handled so much that it sounds like mere spiritualism or sentiment, and it is made light of. Craftsmen who truly do it are hard to find anywhere. But in its original sense, it must have been a highly advanced "invisible technique" of compressing information and sealing it inside an object. True work means compressing, almost excessively, the invisible context of a life and carefully thought-out thinking into a visible, physical result. It means redesigning your output so that it becomes the trace of your own life. It also takes a skill not to force this on others but to let it blend in naturally. Wanting to boast of an achievement, wanting to satisfy a need for approval, wanting to leave a trace of a life: these are completely different things.

A trap lies close by here, the resignation that says "only those who understand will understand." That resignation is pointless too. Layered work holds an overwhelming strength against the passing of time. Thin products and content made for easy consumption cycles degrade at once and are thrown away as trash. Layered work like lacquerware survives centuries of wind and weather and gains in value as time passes. This value is not the value of a thing. It is a life that integrates the history of its origin, the life the maker lived, and the era and the history that have passed since. So it is clear that the question is not one of form, style or technique.

In the world of lacquer, they say that after the lacquerer has finished, it takes nearly a hundred years before the piece is truly complete and its most beautiful color comes out. The work is designed to keep functioning on a time scale that outlasts both maker and buyer. What you make shows its true worth after you are dead. The buyer, too, will not see its worth within his own lifetime. Only after the lacquerware has been handed down through at least three generations, around the grandchildren's time, does its worth appear.

This is proof that the Japanese of the past held a sense of time stretching several generations beyond the short span of one life, not as an idea but in their skin. Lacquerware proves it.

In this turbulent age, the way of working and the way of living we should aim for are found here. Do not spend time as a mere currency. Take time as a material and concentrate it. Give up the measure of efficiency, how much you can process in an hour, and change the question to one of density: how many years of experience and knowledge can I compress into this single moment of output?

It is an attempt to lift your work from mere labor into the crystallization of a life. You do not need to ask for other people's understanding right away. In a world where everything turns fluid and disappears, only highly concentrated work will remain as the one trace proving that you were here.

Stop selling your time in slices, and layer your life. That, for us, is the one and greatest strategy for survival left, the way to run alongside AI and, in the end, to go beyond even the old age that is coming.
