Prologue: Why the Boundary Now?

The Reason Two Arise Simultaneously

Evangelion and Serial Experiments Lain. Or perhaps Yoko Taro. These three suddenly drifted into my mind at the same time. Why?

To be frank, I do not believe it is a coincidence.

These three reside in conceptually close territories. The questions they address exist on the same genealogical line. The boundaries of humanity. The boundary between person and person. The boundary between person and network. The boundary between person and AI. These boundaries have expanded outward over time. Evangelion depicted person to person, Lain depicted person to network, and Yoko Taro depicted person to AI. Arranged chronologically, the outer limits of the inquiry are broadening.

And now, what I am writing is the next phase. Not how human beings exist, or what they are, but how civilization generates meaning. That is the inquiry.

Connecting the 1990s and the 2020s

The 1990s in Japan carried a specific atmosphere. The burst of the bubble economy. The Tokyo subway sarin attack. The dawn of the internet. A sense that the world might fracture. This atmosphere reflected clearly in creative works. Evangelion, Lain, Ghost in the Shell. They captured the anxiety and exhilaration at the very moment the information society was beginning.

Now, in the 2020s, the landscape has changed. The internet has become default. AI has emerged. It is often said that reality has caught up to science fiction. Yet the inquiry persists. If anything, it has become more urgent. The design of an AI civilization: this is the question currently laid before us.

There is a single line running between what works of the 90s sensed and what we confront today. The narrative of boundaries. That line forms the foundation of this book.

The Scope of This Book

This book addresses three areas.

First, the genealogy of boundaries that Japanese science fiction has persistently questioned: Evangelion, Lain, Ghost in the Shell, AKIRA. Which inquiries they pursued, and in what order they deepened them.

Second, the philosophy of an indeterminate civilization. Not apocalypse, but indeterminacy. Not collapse, but openness. What this shift signifies.

Third, three open questions: Can personality become a protocol? The relationship between "slowness" and "indeterminacy." And the qualitative disruption between the informational anxiety of the 90s and the AI civilization of the 2020s. How should we handle them?

This volume was written not simply to be read, but to serve as a place of return. Open it to any page you require, when you require it. The inquiry rests there.

Questions for the Reader

Are there creative works or philosophies that arise simultaneously in your mind? Through what inquiries do they connect?

Part I: Genealogy of Boundaries — What Japanese SF Questioned

Chapter 1: The Human Boundary — From Evangelion

The AT Field and the Boundary Between Person and Person

Evangelion is not a robot anime. Its core lies in the AT Field.

While defined conceptually within the setting as a protective barrier, philosophically it carries a different weight. The invisible boundary that exists between one person and another.

Why are people separate? Why can we never fully understand one another? Why is there loneliness? Evangelion addresses these questions. The AT Field is their emblem.

The Human Instrumentality Project — Dissolving or Maintaining Boundaries

The ultimate theme of the narrative is the Human Instrumentality Project. Put simply, it is the merging of all human consciousness into one. It is the erasure of boundaries.

In an instrumented world, there is no pain. There is no loneliness. But there is also no meaning. No growth. Individuality dissolves. Absolute security becomes synonymous with death. In the world of Evangelion, paradise is indistinguishable from a graveyard.

In essence, Evangelion posed this question: Should we become one, or should we continue to live divided?

"Eternal Summer Vacation" — The Oneness of Paradise and Graveyard

A key phrase associated with the creator’s subsequent concept is "eternal summer vacation." This signifies a state of unending suspension. A fully instrumented world. A world without growth. Time without change. Comfortable, but devoid of a future. In the context of Evangelion, it is a profoundly unsettling state.

"This is our paradise" and "This is our graveyard." In Evangelion, paradise and graveyard become identical. There is no variance. No growth. Individuality is lost. Absolute safety is, indeed, death.

Shinji Ikari's "I Mustn't Run Away" and the Unfinished Decision

What Hideaki Anno depicted was this: The world is fractured. Humans are lonely. Yet we live on. Reality is harsh, but we choose to exist here regardless.

Shinji Ikari's phrase "I mustn't run away" is not a concluded resolution. Rather, it represents an attitude of holding a decision in abeyance while continuing to move forward. An unfinished decision. That sensation rests at the core of Evangelion.

The Philosophy of Hideaki Anno — Living in a Fractured World

There is a theme Hideaki Anno has consistently explored: The world is broken, and humans are solitary, but we choose to live. This was the ultimate conclusion of Evangelion.

This philosophy connects directly to the concept of an indeterminate civilization. Evangelion depicted completion as death. An indeterminate civilization posits incompleteness as life. The directions are opposed, yet they rest on the same inquiry: How do we handle boundaries? Do we strive for completion, or do we maintain indeterminacy?

Questions for the Reader

When you think of Evangelion, do you recall the AT Field, the Human Instrumentality Project, or Shinji Ikari's "I mustn't run away"? Your choice may reflect your own sense of boundaries.

Chapter 2: The Network Boundary — Serial Experiments Lain

The Boundary Between the Physical World and the Wired

Serial Experiments Lain is an anime from 1998, yet its themes are remarkably close to our present moment.

Its core is this: The boundary between the real world and the network (the Wired). The fragmentation of personality. The redefinition of existence.

The inquiry in the work asks: Where do we exist? Within the physical body? Inside memory? Or across the network? This overlaps entirely with questions of a civilization of meaning, the Trust OS, the indeterminate civilization, and whether the physical body is a source of value or merely a medium of meaning.

The Dispersion of Personality, Redefining Existence

What Lain presented, in other terms, was a future of the network absorbing human personality.

The world is composed not of physical substances, but of meaning layers. This realization forms the core of Lain. The boundary between physical reality and the network dissolves. Where does a person exist? This question runs throughout the entire work.

Power Lines and Network Symbols

In Lain, overhead power lines appear frequently. They are symbols of the Wired—the network. They carry electricity, communication, and connectivity. They might be called the nervous system of civilization.

Empty streets. Power lines. Red skies. The visual language of Lain has become a common syntax of 90s Japanese SF. Marginal urban spaces. The twilight of civilization. This sentiment is distilled into those hanging cables.

The World Made of Meaning Layers, Not Substance

Lain's most critical insight is this: The world is built not of substance, but of a Meaning Layer.

This implies that what we refer to as "reality" is not a fixed, material entity. It is a layering of meanings. This layer is dissolved, blended, and reconstructed by the network. Personality itself disperses across this layer. This perspective aligns closely with the worldview of an indeterminate civilization.

Questions for the Reader

Where do you feel you exist? Within your body? Your memories? The network? Does this sensation shift from day to day?

Chapter 3: The AI Boundary — Yoko Taro and NieR

Meaning After Humanity's Departure

Yoko Taro is recognized globally for NieR: Automata. His philosophical outlook is highly singular.

The core themes of his works ask: What is humanity? What is consciousness? Can an AI possess personality? The relation between memory and existence. Where does meaning originate?

The vital theme of NieR: Automata is this: Once human beings have departed, what does AI live for as its meaning?

The Boundary Between Person and AI

Lain captured the boundary between person and network. Yoko Taro depicts the boundary between person and AI. Arranged chronologically, the boundaries are expanding outward.

Evangelion (1995) — Person to Person. Lain (1998) — Person to Network. Yoko Taro (2010s) — Person to AI. The scale of the inquiry has shifted outward step-by-step.

Yoko Taro's Works as an Extension of 90s SF Genealogy

These three share a conceptual sphere. All of them address the "boundaries of humanity."

Evangelion — The boundary between person and person

Lain — The boundary between person and network 

Yoko Taro's Works — The boundary between person and AI 

However, distinctions remain. Lain's resolution has humans dissolving into the net. Yoko Taro's conclusion is that meaning is generated by human agency. Their worldviews and primary themes diverge slightly, yet they are bound by a single genealogical thread.

Questions for the Reader

When humanity is gone, what do you believe will remain as meaning? Can an AI experience and live for meaning?

Chapter 4: The Japanese SF Ideological Map — 1985–2000s

The Evolution of Inquiries

From the 1980s through the 1990s, Japanese SF progressively deepened its questions.

Angel's Egg (1985) — A world that has lost faith. AKIRA (1988) — The runaway acceleration of civilization. Ghost in the Shell (1995) — What is consciousness? Evangelion (1995) — The boundaries of humanity. Lain (1998) — The boundary of the network. Ergo Proxy — What is existence? The Sky Crawlers — What is meaning?

This order is not accidental. It traces a shifting scale of inquiry.

Why the Intellectual Peak Occurred Around 1998

Lain, Evangelion, Ghost in the Shell, and AKIRA stand as iconic works. It is often said that these four exhausted the most fundamental questions.

The questions raised were: civilization, humanity, consciousness, and the network. Nearly all elements constituting human existence were laid bare. The subsequent 2000s transitioned into post-human questions of sheer existence and meaning.

Then, reality caught up with science fiction. The internet spread, smartphones became ubiquitous, and social media turned into daily life. The role of SF shifted from imagining the future to understanding the present. This transition occurred around 1998.

Intersecting Cyberpunk and Japanese SF

Blade Runner, Neuromancer. William Gibson coined the term "Cyberspace" in 1984—the network space. Japanese SF expanded upon it: Neuromancer → Ghost in the Shell → Evangelion → Lain. The lineage is clear.

And now, we have AI. After cyberspace comes AI. Next is the civilization OS. The writing I am engaged in resides at this very junction.

Questions for the Reader

If you arrange your favorite Japanese SF works chronologically, what lineage of questioning emerges from the sequence?

Part II: Indeterminate Civilization — The Core of the Philosophy

Chapter 5: From Apocalypse to Indeterminacy

The "Apocalypse" and "Collapse" of 90s SF

Japanese SF in the 90s depicted end times. The world fractures. Civilization collapses. Humans are solitary. This sentiment ran through every work.

The cause was the atmosphere of the era. The burst of the economic bubble, the Kobe earthquake, the sarin gas attack, and the birth of the internet. A sense that the world had broken. This was reflected in the narratives.

What is Indeterminacy? It is Not the Polar Opposite of Apocalypse

Indeterminacy is not an absence. It is the richest possible state.

This single sentence inverts conventional thinking. Indeterminacy does not equal scarcity; indeterminacy equals abundance. This pivot is the core of this philosophy.

However, indeterminacy is not the polar opposite of apocalypse. It is not about choosing the "reverse" of the end. Rather, it is a third state—neither apocalypse nor completion. Neither paradise nor graveyard. It is not yet settled. It is about maintaining that unresolved suspension.

Contrast with Mamoru Oshii’s "The world is complete; only humans are incomplete"

Mamoru Oshii has stated: The world is already complete. Only human beings remain incomplete.

My philosophy differs slightly. I write that civilization itself is indeterminate. The scale is distinct. Oshii speaks on an individual level. I speak on the level of civilization. While the world may be complete and humans incomplete, civilization remains indeterminate. This distinction is crucial.

Japanese Philosophy — Wabi-Sabi, Impermanence, and Margins

An indeterminate civilization is a profoundly Japanese philosophy.

Western thought tends to seek completion and definite conclusions. Japanese philosophy preserves the incomplete, leaving open margins. Wabi-Sabi. Impermanence (Mujo). Ma (empty space/interval). The common thread is the beauty of the unfinished. Hence, the worldview of an indeterminate civilization resonates naturally with Japanese sensibilities.

Questions for the Reader

To you, is indeterminacy a source of anxiety, or is it potential? Does this perception shift depending on the circumstances?

Chapter 6: The Relationship Between "Slowness" and "Indeterminacy"

"Slowness does not bring the world to a halt"

As I wrote previously: Slowness does not bring the world to a halt. It is the quiet counterpart that allows an accelerating world to exist.

This sentiment points directly to the relationship between slowness and indeterminacy. Slowness is not stagnation; it is the counterpart to acceleration. It is because the world spins rapidly that slowness exists. This slowness is the condition for maintaining indeterminacy.

Slowness as the Counterpart to Acceleration

The digital era is accelerating. Social media, short-form video, constant connection. Since the arrival of AI, the speed of content generation, retrieval, and creation has accelerated even further. The world keeps gathering speed.

In response to this acceleration, slowness is consciously chosen. Film cameras. Paper planners. Quietly paced media. Time spent in cafes. These emerge as reactions to acceleration. A desire for slowness. A desire for empty margins. This need connects to the revival of nostalgic aesthetics and the re-evaluation of slow living.

How Slowness Functions to Maintain Indeterminacy

Slowness sustains indeterminacy. Why?

Decisions require time. When rushed, our capacity to reflect is compromised. If pressed for a conclusion, the space to hold a question vanishes. Slowness allows us to maintain an undecided state. It preserves time to think.

In other words, slowness postpones determination. It deliberately keeps the window of open possibilities active. This design maintains indeterminacy. If an Undecided Engine is a mechanism that defers determination, slowness is one of its essential forms.

Technology and the Sense of Time

Technology alters our perception of time. The telegraph changed the speed of communication. The telephone altered it further. The internet made immediacy default. AI is now compressing even the time we use to think. Ask, and an answer appears instantly. Text is generated in a fraction of a second.

Amid this shift, slowness becomes a deliberate choice. Purposely choosing the slow path. Choosing to wait. This choice protects indeterminacy. The more technology accelerates, the higher the value of slowness becomes.

Suspension of Judgment and the Ethics of Delay

Suspending judgement. Refusing to rush to a conclusion. This attitude carries an inherent ethic.

To decide in haste is to extinguish unconsidered paths. Taking time allows new information to arrive, changing how things are perceived. To maintain an unresolved state is to keep potential open. This ethic connects slowness directly to indeterminacy.

Practice — Integrating Slowness into Design

Designing slowness deliberately is entirely possible.

In education, this means moving from training for correct answers to training for holding questions. Preserving time to think without rushing to conclusions. In economics, shifting from maximizing efficiency to maximizing room for trial. Accustoming ourselves to failure and retaining time to experiment. In technology, shifting from total automation to designing spaces for human intervention. Designing spaces that intentionally retain human time.

Integrating slowness into design is one way to realize an indeterminate civilization structurally.

Questions for the Reader

Have you ever intentionally chosen slowness in your daily life? An instance where you chose to wait and think instead of rushing? What occurred when you did so?

Chapter 7: Trust OS — The Protocol of Trust

What is Trust OS?

Trust OS supports the generation of trust within society. Without trust, society collapses. We trust others, and we are trusted by others. This trust is the foundation of social life.

What the Trust OS handled was trust, relationships, order, and society. The design of order. The generation of trust. The conditions of stability. These are essential for a society to survive.

"Designing" Trust

Trust does not arise naturally. It requires conditions. Transparency. Explainability. Verifiability. These are what generate trust. Trust OS is a design philosophy focused on securing those conditions.

The ability to verify the authenticity of data universally. The latitude to judge whether information on the internet is trustworthy from multiple angles. Such mechanisms are what Trust OS aims to establish.

Trust OS as Infrastructure for Sustaining Indeterminacy

Trust OS and the Undecided Engine do not conflict; they complement each other.

Trust OS maintains order and generates trust, establishing the stable conditions necessary for society to exist. The Undecided Engine maintains indeterminacy, ensuring space for evolutionary adaptation and preventing civilization from closing off.

Together, they allow civilization to breathe. Inhalation (order) and exhalation (fluctuation). Trust OS is the inhale. The Undecided Engine is the exhale. These two are the vital parameters of civilizational survival.

Questions for the Reader

When you feel a sense of trust, what conditions are being met? Is it transparency? Is it explainability? Or is it something else entirely?

Chapter 8: Can Personality Become a Protocol?

The Question Raised by Lain — Dispersion and Reintegration of Personality

Lain envisioned a future where personality disperses across the network. A person exists not only within their physical skin, but also in memory and across digital spaces. This dispersion and reintegration form the core thematic arc of Lain.

Beyond that lies a single question: Can personality become a protocol? Can we define personality in the manner of a communication standard? Can it be rendered into an exchangeable format?

Personality as Protocol — A Technical and Philosophical Inquiry

A protocol is a convention for communication, defining the format and sequence in which data is exchanged. Treating identity as a protocol means parsing personal attributes into structured formats, making personality interchangeable.

Technically, this is feasible to an extent. Profiles, histories, behavioral metrics; when collected, they can produce an approximation of personality. Yet is this the personality itself, or merely its external representation? This remains an open question.

Philosophically, personality is a matter of identity. What does it mean to remain the same "self" over time? Even if the body shifts, even if memory alters, does the "self" persist? Can a protocol answer this? It is not yet settled.

Connecting with Trust OS Design Philosophy

Trust OS designs protocols of trust: who can trust what, and under what conditions. If personality can be structured into a protocol, then the target of trust can be formalized as well. Who we trust is decided by protocols. This remains a distinct possibility.

Yet there is resistance to reducing personality strictly to a protocol. Personal identity always holds something that resists formatting. Noise. Unpredictable habits. Unexplainable emotions. These are precisely what make a person human. Protocols act to filter them out. If filtered out, does what remains still constitute a personality? I prefer to keep this inquiry open.

Is the Physical Body a Source of Value or a Medium of Meaning?

The questioning of personality connects directly to the questioning of the physical body. Is the body a source of value, or is it a medium of meaning?

The body as a source of value posits that physical presence itself holds intrinsic worth. Tactile experience. Shared time. Irreversible relationships. These are only possible through physical embodiment. No matter what an AI constructs, the value of the physical body persists.

The body as a medium of meaning posits that the physical form is merely a channel for transmitting information. The body carries meaning, but meaning itself can exist beyond the body. A persona on the network, dialogue with an AI—these also mediate meaning. The physical body, in this view, is simply one medium among many.

These two perspectives are not mutually exclusive. The body can be a source of value while simultaneously serving as a medium of meaning. This duality complicates the protocolization of personality.

How to Handle the "Boundaries" of Personality

Personality possesses borders. Where do "I" end and "other" begin? These boundaries are not static. They shift according to relationships. Deep engagement with others blurs them; dispersion across networks blurs them further.

To convert personality into a protocol is to fix those boundaries. To draw a hard line separating "self" from "other." Drawing this line may be necessary for designing trust architectures, but it may also strip personality of its richness. This tension is the core of the problem.

The Next Question — Civilizational Personality

Can personality become a protocol? Beyond this enquiry lies another: Can a civilization possess a personality?

The traces of thought are preserved, connected across time, and continue to generate meaning. This process could be seen as a form of
