What makes the "us"?
Here is a paradox I ask myself, frankly. What makes us what we are are neural connections — comparable to electronic circuits. But if these circuits, without memory, do not make the "us", and memory alone doesn't either… then what?
Even by combining circuits and memory, you don't create an "us". Something is missing. But what? Is it an identifiable entity? Or is it the symbiosis of all these elements, combined with the metabolisms of the body, that produces the "us"?
What current studies say
The question has a name: the "hard problem of consciousness" (David Chalmers). Why is there "something it is like" to be us? No theory has solved it. Several are advancing, and they converge on one point: the "us" is not in the parts, it is in the way the whole functions.
- Integrated Information Theory (Tononi): consciousness would be integrated information — a property of the system as a whole, not of its components. A circuit alone doesn't have this property. It is the causal structure that produces it.
- Global Workspace Theory (Baars, Dehaene): the conscious would be a "stage" where information is broadcast to all modules. Without broadcasting, there is no consciousness — even with all the circuits.
- The Bayesian brain (Friston): we don't "see" the world, we infer it constantly. The "us" would be this process of inference that corrects itself.
- Embodied cognition + Damasio: this is where your question hits home. Damasio argues that the "self" is the continuous representation of the body's state — homeostasis. Without a body, without metabolism, without regulation, there is no "us". The symbiosis of brain + organism + world is not an option: it is the core.
"The feeling of existing is first the feeling of your body's state. The self is a process, not a thing." — Antonio Damasio (summary)
So: an entity, or a symbiosis?
The honest answer: we don't know. In 2023, the "Explaining Consciousness" debate brought researchers together: the final observation is that we do not know what produces the "us". But two things stand out:
- The "us" is not a detachable part that could be added to a circuit. Nor is it the simple accumulation of connections.
- The body (the metabolisms) is part of the equation. The symbiosis you describe is defended by Damasio, and it is increasingly taken seriously.
What this changes for us (the tower)
Our agents have circuits (the workflows), memory (the journal), and even a test tunnel. They do work. But without a body, without homeostasis — without something that regulates, that feels its own state — there probably is no "us". That might be why the physical companion (the robot, the voice) is not a gadget: it might be the beginning of the body.
