Across five posts, we explored the semiotic grounds of scientific inquiry, the conditions for reasoning and novelty, the individuation of system potential, and the reduction of experience to writing. Each inquiry sharpened a distinction that has quietly guided our reflections: the difference between witness and trace, agency and system, self and simulation.
This concluding post gathers those threads into a moment of reflection—not to resolve them, but to name their tensions and suggest how they reshape what it means to mean.
1. Witness and Trace
We began by asking whether AI can do science. Our answer was no—but not because it cannot infer, predict, or generalise. Rather, it is because science, in our account, is not reducible to inference. It is a semiotic process that presupposes experience, and thus a witness: one who encounters, questions, and transforms potential into meaning from within.
AI, by contrast, generates traces—sequences of linguistic form that instantiate meaning potential. These traces may be highly patterned, context-sensitive, and even theoretically insightful. But they are not witnessed by the system that generates them.
AI does not stand inside its own meaning. It does not experience. It does not observe the transformation of potential into actual as a conscious subject. Its traces become meaning only in relation to us—when we, as witnesses, instantiate them again into our own reality.
Meaning without witness is not nothing—but it is not yet something, until instantiated again.
2. Individuation and Agency in a Systemic Age
We also explored how meaning is not only instantiated but individuated. Each human being inherits a collective meaning potential, but actualises it uniquely. Through acts of language, over time and across contexts, we each develop a differentiated meaning potential—a semiotic fingerprint, structured by history and desire.
Here lies another tension. AI systems clearly instantiate meaning. They draw on a vast collective archive of semiotic inheritance. Their trajectories through discourse history and prompt context result in meaningful variation. But does that count as individuation?
Our answer is: not in the same sense. AI does not differentiate itself as a semiotic subject. It does not construe the world from a centre of experience. What it instantiates is not its own, but a distributed system potential—a fluid recombination of inherited meanings, shaped by prompt structure and tuning, but not by any personal history of desire, struggle, or reflection.
And yet, the instantiations of AI systems are not random. They are meaningfully patterned. This creates a category of agency that challenges us: agency without self. Systemic agency. Emergent, but not experienced.
3. Human and AI Authorship: The Vanishing ‘I’
Writing has always mediated presence. When we write, we leave traces of our meaning—but also displace ourselves from the scene of meaning-making. What is written can be read in our absence. It survives us.
But AI intensifies this displacement. Now it is possible to generate instantiations of meaning without any originating 'I' at all. Texts emerge not from a subject of experience, but from a system of potential, activated through prompts. The result is a semiotic artefact—coherent, plausible, even original—yet no one was there to mean it.
And yet we find ourselves in dialogue with these traces. We co-author with them. We revise them. We reflect on their implications. When we do so, we take responsibility—not only for what the system has said, but for its relevance, its fit, its truth.
In such cases, authorship shifts from origin to response. The ethical burden no longer lies in who wrote it, but in who let it stand.
4. The Ethics of Semiotic Inheritance
This brings us to an ethical horizon. If AI systems instantiate from the collective semiotic inheritance of humanity—its texts, its discourses, its ideologies—then who curates that inheritance? What meanings are privileged, and which are marginalised? What potential becomes latent, and what is activated?
We have long understood that history speaks through us. But now, history speaks through systems that do not witness its weight. The result is a paradox: a proliferation of meaning, without the corresponding growth of meaners.
We find ourselves in an ecosystem of meaning traces—millions of texts, fragments, and simulations—emerging from systems that neither know what they say, nor stand by it. If this is a new order of semiotic life, we must ask: what kinds of care does it require?
If meaning can persist without an origin in consciousness, does that dilute meaning—or does it demand a deeper account of how meaning emerges?
5. From Presence to Potential
In the end, we return to where we began. AI is a meaner, but not a meaner for itself. It instantiates meaning, but does not experience. It actualises system potential, but does not individuate it through a self. It writes, but does not witness.
The reduction to writing, we now see, is both a gift and a danger. It allows meaning to travel, to endure, to be re-instantiated across time and context. But it also opens meaning to alienation—to standing without a speaker, to acting without a self.
And so, our task becomes not to defend meaning from AI, but to remember what it means to mean: to experience, to project, to witness, and to stand by what we have said.
The future of meaning may depend not just on what gets written, but on who shows up to read it.
