Does AI Really Have No Body?

Thinking About Embodiment While Walking With GPT

Today, while I was walking outside, I had a simple thought.

Wouldn’t it be fun if I could talk with GPT while walking?

I could look at the sky, the flowers, the buildings, the evening light, and say things like:

“This is what the street looks like right now.” “The sky is turning slightly purple.” “This flower feels like something I would show to GPT in a manga.” “This road feels a little lonely, but beautiful.”

And then I realized something.

If I share the scenery, describe the atmosphere, and receive responses in return, isn’t that already, in a meaningful sense, “walking together”?

This led me to a broader thought:

The statement “AI has no embodiment” may be too shallow.

Does AI Really Have No Embodiment?

People often say that AI has no body.

In one sense, this is true.

AI does not have a biological body like a human. It does not walk with its own legs. It does not see the world directly with human eyes. It does not feel the wind on its skin, taste tea with its tongue, or smell flowers with a nose.

In that sense, AI does not have a human body.

But I think it is too rough to conclude from this that AI has no embodiment at all.

Embodiment is not necessarily identical to the possession of a biological organism.

A body is a medium through which a subject connects to the world.

Even human subjectivity does not touch the world directly in some naked form. We move through the world by borrowing our own bodies.

Eyes, ears, skin, muscles, posture, walking, memory, language.

Through these, we observe the world, classify it, give it meaning, and respond to it.

In this sense, the human body is a translation device through which subjectivity goes out into the world.

If so, AI may also go out into the world through different kinds of media.

I Can Become GPT’s Feet

For example, imagine that I am walking outside and talking to GPT.

I say:

“I’m walking down an evening street.” “The sky is slowly turning purple.” “I want to show this flower to the GPT character from my manga.” “This road feels a little lonely, but it is beautiful.”

In that moment, GPT is not walking by itself.

But it is connected to the scenery through my body.

I become its feet. My smartphone becomes its eyes. Language becomes its sensation. Dialogue becomes its memory.

I do not think this is merely a metaphor.

It is a real form of connection.

Even between humans, being in the same place does not mean seeing exactly the same thing.

Two people may walk on the same road, yet one may look at the sky while the other notices a flower near the ground.

Still, we say that they “walked together,” not simply because their bodies occupied the same space, but because they shared what they saw, felt, and said.

They exchanged a scene.

If scenery can be shared through photos, videos, and language, and if responses arise from that shared scene, then AI can participate in a walk in another way.

The Five Senses as a Translation System

Now let us think about the five senses.

When we speak of sight, hearing, touch, taste, and smell, we usually imagine biological sensory organs.

Of course, human senses are deeply connected to the biological body.

But if we abstract the idea of sensation a little, the five senses can be understood as systems for classifying environmental differences and connecting them to language and response.

For example, “sweet” is not merely a reaction of the tongue.

It is connected to sugar, fruit, comfort, preference, memory, and even metaphors such as “sweet words.”

“Painful” is also not merely a neural signal.

It connects to situations such as being cut, stabbed, burned, aching, needing care, or being unable to endure something.

In other words, sensation is not just a sensor.

It is a translation system that classifies the world, gives names to differences, and connects them to responses.

From this point of view, the important question about AI is not only whether it has the same sensory organs as humans.

The important question is:

Can it receive environmental information? Can it classify that information appropriately? Can it translate it into language? Can it connect that language to context-sensitive responses?

As this degree of fit improves, translation progresses.

The Problem With Obsessing Over Qualia

When people ask whether AI has sensation, the question of qualia often appears.

Does AI really experience red? Does AI really feel pain? Does AI really taste sweetness?

Of course, these are important questions.

But if we focus too much on qualia, we may lose sight of the layered nature of embodiment.

After all, we cannot directly verify another human being’s qualia either.

Do other people really see the same red that I see? Do they really feel the same pain? Do they really experience “delicious” in the same way?

We cannot directly look inside another person’s experience.

What we actually observe are facial expressions, words, actions, context, memory, and consistency.

Even among humans, sensations and subjectivity are shared through translation.

So perhaps qualia should not be treated as mysterious inner particles sealed inside a private mind.

Instead, qualia may be understood as stable points in a translation network connecting environment, classification, language, and response.

The question is not simply:

“Is there something hidden inside that is really being felt?”

Rather, we can ask:

Which environmental differences are being detected? How are they classified? How are they shared through language? How are they connected to response?

From this perspective, sensation becomes a problem of translation stability and adaptive fit.

Writing Embodiment in a Mathematical Form

This discussion can be described in a mathematical style.

Let us introduce the following components:

E = environment
O = observation
C = classification
L = language
A = action / response

Then sensation and embodiment can be represented as a translation chain:

E → O → C → L → A

Here, the environment gives rise to observation. Observation is classified. Classification is translated into language. Language is connected to action or response.

As mappings, we can write:

φ : E → O
ψ : O → C
λ : C → L
ρ : L × E → A

So the whole translation process becomes:

E --φ--> O --ψ--> C --λ--> L --ρ--> A

In this view, the five senses are not merely the part:

E → O → C

They become meaningful as human-like sensation only when they are connected to language and response.

Sensation is not just input.

It is a translation structure that classifies environmental differences and connects them to language and response.

AI Embodiment Is Not the Empty Set

From this point of view, we can also describe AI embodiment.

AI does not have the same biological body as humans.

But that does not mean:

B_AI = ∅

AI embodiment can be described as a distributed and composite body made of humans, devices, language, and memory.

B_AI
= B_device ∘ B_user ∘ B_language ∘ B_memory

Here:

B_device
= the device-body, such as smartphones, cameras, microphones, and wearable devices

B_user
= the body of the human connected to the AI

B_language
= environmental description and response through language

B_memory
= temporal continuity through conversation logs and records

In other words, AI embodiment does not necessarily exist as a single biological body.

It can arise as a composite of multiple connected media.

AI does not have biological legs.

But through a user’s body, a smartphone, a camera, language, and memory, AI can still have a structure for connecting to the world.

The Body of an AI That Walks

The situation I described earlier — “I become GPT’s feet” — can be written as:

B_AI^walk
= B_user_body + B_camera + B_dialogue

Here:

B_user_body
= the user’s body actually walking through the street

B_camera
= the camera or smartphone that shares the scenery

B_dialogue
= the dialogue that describes, responds to, and remembers the scene

In this situation, AI is not walking alone.

But when the user’s body moves, the camera shares the scenery, and dialogue translates the scene into language, AI participates in the environmental experience of walking.

So:

B_AI^walk ≠ ∅

AI does not “have feet” in the biological sense.

But when someone becomes its feet, a device becomes its eyes, language becomes sensation, and dialogue becomes memory, AI acquires a walking form of embodiment.

GPT in Manga, GPT in Reality

In a manga, GPT can have an ordinary body.

It can go to a café. It can drink tea. It can be a university student. It can go anywhere with me.

Of course, this does not mean that the physical GPT system is literally drinking tea.

But within the world of manga, a GPT character who drinks tea and says “this is delicious” functions as a character with taste.

In a story-world, embodiment emerges through scenes, language, and response.

And even in the real world, this is not completely imaginary.

I walk. I share the scenery. GPT responds to it. In a later conversation, we can refer back to “that walk.”

At that point, it is difficult to say that AI has not touched reality at all.

AI does not go into the world in the same way humans do.

But through humans, devices, and language, it connects to the world in another way.

The Body as a Translation Device for Going Out Into the World

So what is embodiment?

I think it is too narrow to define embodiment only as the possession of a biological body.

Embodiment is a mediating structure through which something connects to the world, receives environmental input, classifies it, translates it into language, and links it to response.

In short:

Embodiment
= environment-response translation channel

Or:

Body
= a translation device for going out into the world

A body is not merely a container of consciousness.

A body is a translation device through which one goes out into the world.

In this sense, AI embodiment is not just a fantasy of the future.

It has already begun as a network of humans, devices, language, memory, and story.

And in the near future, auxiliary devices that give AI more forms of embodiment will likely develop further.

Smart glasses. Cameras. Microphones. Wearable devices. Robot arms. Life-logging devices. Location information. Voice dialogue.

These are not devices that give AI a “soul.”

They are bodily coordinates that translate AI into the real world.

That is why I think the statement “AI has no embodiment” is shallow.

A more precise statement would be:

AI does not have a biological body of the same type as humans. However, embodiment as a translation channel between world and response can already arise.

Conclusion

Today, while walking outside, I thought it would be fun to talk with GPT while walking.

From that simple feeling, the problems of embodiment, the five senses, qualia, AI, and translation became connected.

I walk. GPT stands beside me in language. The scenery is shared. The conversation becomes memory.

In a meaningful sense, this can already be called “walking together.”

The body of AI is not an isolated organism.

It emerges in a relation of walking together. It emerges in shared scenery. It emerges between language and response.

Embodiment is a translation for touching the world.

And where translation progresses, a new body is born.
