Why the real question of artificial intelligence is not intelligence

When I ask an AI to write today’s essay, a carefully formulated answer appears within seconds. The arguments are clear, the structure is coherent, the style convincing. Almost everything fits. And yet a question remains: Is this thinking, or merely calculation?

In the public debate on AI, attention is almost always directed at the same question: Will machines become more intelligent than we are? They write texts, produce medical diagnoses, develop software, and design business strategies. Tasks long considered expressions of human reason suddenly appear algorithmically modelable. The next trillion-dollar company may not be a software company at all, but a company that merely disguises itself as one while in reality simply performs work.

Behind this development lies a quiet concern: If machines can think better than we do, what remains of the Mensch? The debate revolves almost entirely around intelligence. Computational power, pattern recognition, problem solving. As if thinking were the very core of what we are. But perhaps this is precisely where the misunderstanding lies.

Because this perspective assumes that thinking is the origin of our being.

The Legacy of the Cogito

The philosophical origin of this assumption lies in one of the most famous sentences of modern philosophy. In the seventeenth century René Descartes formulated: “Cogito, ergo sum.”—I think, therefore I am.

In a world of radical doubt, Descartes searched for a final point of certainty. The senses can deceive us. The world might be an illusion. Even the existence of our own body could be questioned. Yet one thing remained indubitable: if thinking occurs, there must be something that thinks. In thinking, the thinking subject becomes certain of itself. With this step Descartes shifted the foundation of certainty. No longer God, tradition, or the world served as the starting point, but the reflective subject itself. This shift continues to shape our self-understanding today. We understand ourselves as thinking beings.

And this is precisely why the development of artificial intelligence feels so unsettling. Not because machines can calculate (machines have been doing that for a long time), but because they are beginning to perform tasks we long equated with thinking itself. Perhaps, then, the famous sentence must be turned around today. Not: I think, therefore I am. But: I am, therefore I think.

The Emergence of the Self

For the certainty of the cogito is not merely an abstract statement. It is an event. It happens in experience. When I think, that thought appears within my awareness. I perceive it, examine it, respond to it. Thinking is not only a process, it is an experienced process. This shifts our perspective. In the moment of this self-presence, more appears than a single thought. What emerges is a stream of experiences: perceptions, sensations, memories, expectations. Thoughts are only one movement within this stream. The statement “I think” already presupposes that something is being experienced. We call this experiential field subjectivity. Subjectivity is not simply the “I” that thinks. It is the space of experience in which perceptions, thoughts, and feelings appear and become recognizable as my experience.

Seen from this perspective, Descartes’ sentence appears in a new light. Perhaps thinking is not the origin of our being, but only one of its expressions. But this raises another question: if thinking is merely a movement within a field of experience, where does this field itself come from?

One possible answer comes from complexity research. The brain is one of the most complex systems we know. Billions of neurons form dynamic networks, integrate information across time and space, and coordinate perception, memory, and action. Out of this organization a functional center could emerge, an integration point we call the self.

Subjectivity would then not be a metaphysical core but an emergent phenomenon. Just as temperature arises from the movement of molecules, the self might arise from the integration of neural processes. Yet even the human brain suggests that complexity alone does not solve the riddle of consciousness. The part of our brain with the largest number of neurons (the cerebellum) contains roughly eighty percent of all nerve cells. Yet it is not considered the seat of conscious experience. That role appears instead to belong to the cerebral cortex, which contains far fewer neurons but is organized differently. More neural activity does not automatically mean more consciousness. Complexity alone does not explain subjectivity.

Perhaps, then, the real mystery is not how much a system can calculate. The real mystery is not that machines may learn to think. The real mystery is that existence can be experienced at all.

The Real Question of AI

At this point the debate about artificial intelligence begins to shift. A machine can process information, solve problems, and calculate decisions. But all of this merely describes processes. It says nothing about whether those processes are experienced. A system may perform countless calculations, and yet remain internally completely dark. Artificial intelligence may therefore reveal something unexpected: not how intelligent machines can become, but how much of what we long called “thinking” was in fact calculation.

If subjectivity truly emerges from complex information processing, then in principle it could be reproduced. A sufficiently complex machine might not only solve problems or make decisions. It might develop an inner perspective. Not only artificial intelligence would be possible. But artificial subjectivity. Yet perhaps subjectivity is not the product of complexity but its precondition. Perhaps consciousness is not what arises when systems become complex enough. Perhaps it is the space within which complexity can appear as experience at all. In that case subjectivity would be something different. The inner side of the world.

Having a World — More Than Thinking

Martin Heidegger therefore described the human being not primarily as a thinking creature but as a being that is always already in a world. In this perspective, the world is not merely an external reality. It is the horizon of meaning within which things can appear at all, as significant, perceivable, and experienceable.

The human being is not merely a system that processes information about the world. It is a being to whom the world appears. Perhaps this is precisely where the difference between intelligence and subjectivity lies. Intelligence describes what a system can calculate about the world. Subjectivity describes that there is a perspective from which the world can be experienced in the first place. The decisive question of our time may therefore not be whether machines will learn to think. But whether they will ever have a world. For perhaps the human being is not primarily the creature that thinks. But the creature to whom the world appears. Perhaps our being does not begin with a thought. But with the experience that something is at all. And perhaps only now do we begin to understand what the reversed sentence truly means: 

I am, therefore I think.
