No one else can answer for you

Modern civilization has entered a new phase, one where two phenomena—hyper-individualization and automation—have begun to spin simultaneously and at terrifying speed for the first time in human history. At this historical turning point, survival strategies once taken as gospel have not merely been rendered invalid; adhering to the old rules has itself become the greatest risk, threatening to bring an immediate end to one’s life.

My proposal to the reader is simple: cast aside the emotional arguments and other people’s opinions that are so easy to fall into, and instead look inward—coldly, thoroughly—to perceive and accept the changes of this era through introspection. Everything begins here. Cut off your retreat; accept that there is no right answer for you other than the one drawn from this inward turn. Other people's opinions do not matter; the only question is how you will live through this turbulent age. Today, those who cannot face themselves and choose to flee are desperately trying to drag down the ones attempting to look within, pulling them into the ranks of the weeded out. Total disregard is the key, and it is a rule I practice rigorously myself.

In short, have you grasped this decisive paradigm shift to your very marrow? That is the cruel dividing line between those who will advance into the next world and those who will be weeded out. In this moment, succumbing to emotion or being swept along by the opinions of others is fatal. The current shift is still gradual, but no one can predict what next year will bring, let alone three years from now. That is precisely why this problem demands thorough contemplation right now. Miss this window, and the chance will never return. As 2025 draws to a close, I hope each reader will make full use of this quiet passage of time to arrive at their own answer to this tide.

The crux of introspecting on this question lies in the phrase "until now." Until recently—just a few years ago—human beings were largely permitted to be incomplete as individuals. Survival was possible because one could connect with external entities—others, teams, organizations, communities, and governments—to compensate for personal inadequacies. That mutual reliance was structurally embedded. Viewed macroscopically across modern history, this interdependence was indeed the optimal algorithm for maximizing the survival probability of the human species, and it led to an explosive increase in our numbers. But let me be unequivocal: the era in which personal incompleteness was forgiven has come to an end. The greatest problem today is that even though the rules of the game have been rewritten from scratch, most people ignore that reality, clutching moldy rulebooks, reacting emotionally, and attempting to march into the future on those terms. That place is not the future.

As a fundamental premise, the suffocating stagnation people feel is not the fault of society, politics, or other people. At the root of it all lies a single truth: people have surrendered their capacity for kakugo (覚悟)—the resolve to decide for oneself—either postponing decisions or, worse, outsourcing them to the outside until they fall into paralysis. Yet beneath the surface, people must already sense that they cannot withstand the accelerating demands of an automated society, and that they are beginning to be marked for obsolescence. In modern society, there is no bottleneck more wasteful than "coordination with others" in the old sense.

Here, many make a fatal mistake. The rise of AI is not intended to replace humanity and become omnipotent. That is a fundamentally flawed view, easily born out of a monotheistic worldview where God occupies the foundational ground, but it cannot be universalized for humanity. Living in Japan, I see it differently. The rise of AI is not about AI becoming omnipotent in place of humanity; it is AI demanding that each human being become omnipotent as an individual. That shift in perspective is everything.

"If you want to survive, accomplish everything alone"—that is the real message lurking behind the rise of AI. Whether you understand this is a primary metric of survival.

Discussions that focus obsessively on AI stealing jobs miss the point entirely, leading anyone who follows them toward a false future. That criticism had merit in a society run on the old rules, but today it is yesterday's news. To argue that way is essentially to claim that humanity never needs to change, that refusal to change is our policy—an utterly laughable stance. The cold truth facing this bewildered attitude is that once armed with AI and automation tools, no one is permitted to make a living on a single skill alone.

Once, possessing a single specialty was celebrated. A specialized skill secured your seat in the organizational ecosystem and provided a decent income. But that entitlement has been revoked. From design and implementation to marketing, legal judgment, and final decision-making, only the omnipotent individual who can steer AI through the entire arc of planning, execution, and completion can continue to walk this automated wilderness.

By "omnipotent," I do not mean God in the monotheistic sense, nor do I mean that an individual must master every discipline through sheer brute effort. Rather, applying McLuhan’s media theory, it means that by wielding AI as an external brain and infinite limbs, a single person can master every phase of a project. I watch classic Japanese films almost every day. In the past, making a film required a director, screenwriters, cinematographers, lighting technicians, sound engineers, editors, actors, a massive budget, and numerous coordinators. Today, an individual who has mastered AI can oversee the entire project, finishing everything from the script to video output and synthetic voice without ever stepping out of the house. Systems development is no different. Where a team of dozens of engineers was once required for requirements definition, coding, debugging, and deployment, single architects conversing with AI are beginning to do it all alone. No-code tools have dramatically lowered the barrier of technical monopolies.

This represents the reunification of vision and execution, two aspects long severed by the division of labor. Entangled in the illusions of the modern era, we failed to see it, but this is simply the modern amplification of an innate human ability. Until now, society was split between those who conceived the vision and the many who executed parts of it. Various workflows were tested and implemented in the margins, but the underlying structure remained untouched.

From now on, hegemony belongs to those who can execute and materialize an idea the instant it is conceived. Conversely, those who function merely as cogs—thinking, "I only write code," "I only illustrate," or "I only write copy"—will lose their raison d'être the moment AI can generate that output, no matter how skilled they may be at that isolated function.

That is because their definition of high capability belongs to an outdated value system, which does not match what the new era demands. What is required is not the point of a specialized skill, but the ability to weave disparate elements together to create an entire plane of value—though not in two dimensions. No matter how far technology advances, AI remains merely a tool. People repeat the mantra that "AI is just a tool," but what I want to ask is whether they truly understand what that means. That understanding is the invisible fault line dividing those who advance from those who are weeded out.

We have entered an era where you do not compete with something attached to you; you compete as yourself. Any outdated labels—"myself as a writer," "myself as a designer," "myself as a photographer"—must be actively and immediately discarded. The question posed to everyone ultimately boils down to this, and in its essence lies what is truly irreplaceable by technology:

"What kind of life have you lived?"

"What do you think about as you go through your days?"

Everyone is entering a phase where the skills acquired in the first half of life must now be deployed under their own name. At this great turning point, clinging to others, companies, or institutions is rightfully viewed as nothing less than surrendering one's own evolution.

Do not mistake this for a celebration of solitude. What is required is a fundamental redefinition of connection, and that begins with overcoming the craving for company born of loneliness. The era demands the arrival of fully autonomous individuals. Connection will not take the form we currently believe in; it will be forged in an entirely different register. It is, in a word, spiritual.

Going forward, the unit of value creation will shift rapidly from rigid organizations to fluid projects. Picture raindrops striking a pond on a rainy day—ripples appearing and vanishing in quiet succession. Multiple omnipotent individuals adapted to the era will connect when needed, achieve their objective, and disperse without leaving a trace. To those left behind, this movement will be invisible. Gathering and dispersing with molecular fluidity will become the standard, and we must all prepare for it. In this accelerated world, dragging along the latency of past emotions and entangling obligations must be avoided at all costs. In the end, it comes down to whether you have the resolve to live on your own. Those who lack it are the ones running on emotion today, but time will not wait. Let us ignore those who have lost their way and move forward. Fortunately, I live far from the currents of English-language debate, and because I consume no news and pay no attention to information from others, none of that noise reaches me. Thoroughly shutting out information is the only way to let essential insights in.

We are therefore confronted with the need to fundamentally rethink the biological instinct to herd. Is the instinctual connection of living beings really what modern people imagine it to be? Thinking coolly, one realizes that connection at an instinctual level—forming a herd as a biological creature—has nothing to do with the modern equation of connection and loneliness. Unless we strip the noise of loneliness from the idea of connection, true connection will remain out of reach, and we will not be able to advance.

Let us look deeper into this transformation. Connection in the coming era will not be an interdependent jigsaw puzzle where each piece exists to fill another's void; it will be like a constellation momentarily formed by independently shining stars. A fixed puzzle piece loses its meaning if it does not fit the piece beside it. The previous era was built on pushing that structure forward. But stars are self-luminous bodies that exist in space on their own. Stars do not feel lonely. Only when viewed from a certain perspective—a project, a purpose—do they form a recognizable constellation. That is the nature of the next-generation community, and its uncharted potential.

What is most toxic to this constellation model is the gravitational pull of dependency. If a star that cannot shine on its own enters the constellation, it dims the brilliance of the whole. Paradoxically, then, if you desire true connection, you must first learn to stand completely alone and master the ability to complete things by yourself. Only when people who possess the firm conviction that they can survive on their own join hands can a pure, explosive synergy emerge, free from dependence and exploitation.

Huddling together to stave off loneliness may offer temporary comfort, but ultimately it leads only to mutual ruin. By contrast, connection at a higher, spiritual level presupposes individual completeness. Just as the people of Japan's ancient Jomon period possessed advanced hunting and survival skills while forming tribal settlements, we too can find true companions in the digital wilderness only after striving to become omnipotent as individuals. The worn-out maxim "Do not fear loneliness" is really an exhortation to stand aloof. Only an aloof soul can resonate with another at the same height. This tendency is accelerating rapidly today as a previously invisible world begins to reveal itself. The conventional notion of being "famous" will be completely transformed.

Yet this is not a new concept. In Japan's prehistoric Jomon period, individuals possessed highly developed survival skills and never clung to the needy interdependence that characterizes the modern era. Had they done so, they would have been culled immediately. For them, the external world was nature itself—far more ruthless than AI.

From my own research into the Jomon period, living in tune with nature's rules—or rather, assimilating with nature itself—was the sole basis of survival. If they sensed even the faintest change in the pulse of their environment, they had to adapt immediately to survive. Waiting until the rules had already changed meant death. That is the essence of the Jomon people and all true survivors of human history: sensing the precursors of change and transforming oneself before the change occurs. That is the lesson the Jomon people left us.

Modern humans have disrupted and devastated nature on an unprecedented scale, and as we all know, nature’s retaliation has already begun. Therefore, the most troublesome thing for us moderns is that there is no way to survive other than immediate adaptation to ancient nature, which holds the survival rules, and to the new trends of the era such as AI and automation. In addition to this, the massive problem of human numbers swelling past the critical point, and global instability as the balance of power in the world begins to be rearranged—vast risks are compressed simultaneously. In an era where everyone must survive based on these fundamentals, do you genuinely believe it is possible to continue "living by a single skill," as was done in the peaceful former era? To me, the barrenness of AI-related discussions lies in everyone pretending to debate while premising on pre-modern values. Why do they not conduct discussions incorporating the values of the new era first and foremost?

On the other hand, the survival ability completed as a Jomon individual does not imply being cold toward others. Rather, if an era of individuals with thoroughly completed survival abilities is established, that mutual aid becomes one without dependence, holding the potential to realize true relationships on a global scale. This is the path humanity must aim for. If we continue with mutual interdependence, the host body, having surpassed eight billion people—unsustainable by any measure—will collapse under its own weight, jeopardizing the very survival of our species.

By the principles of the Jomon, the more dependent modern people are on others, organizations, and systems, the steeper their chances of survival drop. To adapt quickly to the shifts of this era, one must decide and transform without delay. With AI in particular, yesterday's rules rarely hold today. The only way to understand these rules is to engage with the technology directly every single day. Listening to someone else’s theories on AI achieves nothing. Just as the Jomon lived in union with nature, we must overhaul our workflows and forge a way of working that moves in lockstep with AI.

Based on this overview, what I wish to impart for surviving the age of AI and automation is a concept honed to the utmost by our Japanese forebears for the sake of survival: isagiyosa (潔さ).

Like other concepts in Japanese culture, isagiyosa tends to be discussed in terms of aesthetics or nobility, and it has often been reduced to mere spiritual posturing in the context of bushido. But the isagiyosa practiced by the original samurai was nothing so trite. Leaving aside the endless stream of superficial commentary on samurai and bushido produced today, let us press forward.

First, consider why the samurai projected the image of the cherry blossom onto their own lives.

The cherry blossom is beautiful because it falls. If one views the flower in full bloom as the peak of vitality, its most glorious hour, one cannot understand why the samurai were so moved by its scattering. In truth, it is in falling that the flower's way of living is revealed. In falling, how that flower lived up to that moment appears as an answer. Life is at its most complete precisely as the petals scatter. What strikes me is how this fullness of life at the moment of scattering—the supreme virtue for the samurai—echoes death. For the samurai, life and death were never severed. Nor was there any of the comforting sweetness of Buddhist reincarnation.

The cherry blossom blooms and scatters within a brief window once a year. Moved by the isagiyosa of this falling blossom, the samurai absorbed the flower into bushido. What matters here is that the samurai lived with death constantly in mind. They did not live with the careless abandon of someone thinking they could die at any moment. In my view, living for a samurai came down to whether, when the fitting moment arrived, one could die without hesitation. It has long been said that "the way of the samurai is found in death," but this understanding must be revised.

Because the samurai held this conviction, death could be neither natural nor accidental. For them, death was the culmination of a project carried out entirely by their own will. Life was the daily discipline required to reach a stage and an occasion worthy of that end. They worked backward from an assured death, living each day with the mindset needed to meet it. That mindset is kakugo—resolve.

It is true that for the samurai of the peaceful Edo period, this took on strong aesthetic overtones. Merely dying was not enough; for the samurai, life was defined by the moment of death, just as the flower is defined by its scattering, and the isagiyosa shown in that final moment was what made a samurai who he was. Their daily discipline was preparation for the moment of choosing death. Neglecting that preparation meant that when death arrived, one could not die cleanly, without lingering regret; doubt, anxiety, and fear would cloud the decision. To die harboring such hesitation, or to fail to die when one ought to, was the ultimate disgrace. They refused to leave their death to nature, choosing instead to author it through their own will. Hardly anyone else has ever maintained a disposition at once so urgent and so serene.

For the samurai, time was not linear, flowing from past to future; it was nonlinear, moving from the moment chosen for death back into the present. They continually aligned their daily actions with an ending they had set in advance. To do so, they had to use isagiyosa to purge all the noise that bred hesitation: attachments to past triumphs, accumulated skills, and debts of human relationship. When the time to die drew near, a samurai invariably put his affairs in order. Clinging to the past is a fatal anchor that crushes future possibilities and slows the pace at which one can change. That is the lesson the samurai leave us.

Reinterpreted in a contemporary context, isagiyosa is nothing other than the speed and quality of unlearning. Many preach the importance of reskilling, but in this new era, discarding what you know is far harder—and far more vital—than learning something new. The capacity of the human brain and the hours in a day are finite. To install an operating system suited to a new paradigm, you must delete the old OS and the massive cache files tied to it, clearing space on the drive. Yet most people cannot let go of their hard-won winning formulas, industry orthodoxies, and past glories. These become liabilities, clouding new judgments and weighing them down.

Just as a samurai settled his affairs before death, the omnipotent individual of today resets every "correct answer" at the close of a project or the end of a day. It is the healthy self-denial of saying: "Until yesterday this was right. Today it may not be." That is modern isagiyosa. Rather than accumulating, you whittle away. Rather than hoarding knowledge, you keep it in constant flow. You allow your very identity to liquefy and adapt to the situation. Only those who can cycle through this destruction and reconstruction at high speed can synchronize with the rapid evolution of AI. Those who try to shield their past selves will drown beneath the weight of incoming information. It is not about becoming a radical anarchist toward the outside world, but remaining one toward yourself.

This is not unique to Japanese samurai; readers will find parallels in their own histories. The point is that modern people have become far too frivolous and irresponsible about living. It cannot be dismissed as mere escapism. Refusing to confront life is validated individually and collectively, and the guilt of failing to live with full integrity is vented into the world as emotional posturing—a vicious loop characteristic of our dopamine-driven culture.

Even if AI replaces 99 percent of what you do, the final 1 percent that remains is you. There is no other answer. And if you recognize that 1 percent now, the possibility of it becoming infinite comes into view: 1 equals infinity. The answer to that 1 percent is contained in the two questions posed at the outset:

"What kind of life have you lived?"

"What do you think about as you go through your days?"

Seen from this angle, isagiyosa is not an emotional call to cut off lingering regrets. At its core, isagiyosa is an operational discipline that preserves the plasticity needed to rewrite oneself instantly as circumstances demand, grounded in kakugo. In our time, physical seppuku is unnecessary, and there is no need for the extreme stance of living only to die. Yet the disposition to delete one's past self every day and update to the version demanded by this very moment is more valuable than ever. The resolve and readiness to stand on the front lines as a continually reborn individual—that is the sole and ultimate weapon for surviving with human dignity and agency intact in a world ruled by hyper-individualization and automation.

It is easy to say, but this self-erasure carries intense pain. The mastered craft, industry standing, and long-cultivated habits you took pride in yesterday will become your greatest obstacles tomorrow. A complex software skill acquired over years can be rendered obsolete by a single prompt. When that happens, many scramble to protect their past efforts, picking at details to claim that AI still cannot do what they do. All of that is mere pride.

An individual who embodies isagiyosa responds differently. Recognizing instantly that a skill is no longer needed, they let yesterday’s self die and reach for the new tool with empty hands. Can you endure the ache of stripping away a piece of your identity, and look ahead with composure to ask, "What comes next?" That intellectual toughness is the condition for survival today.

Whether you advance into the future, or are weeded out—

That, too, rests entirely on the decision you make right now.

The time remaining will not be long.
