The 'hard problem' of consciousness, dating back to Leibniz, posits that no third-person description of the brain's mechanics can explain first-person experience. If you enlarged a brain to the size of a mill and walked inside, you'd see parts moving, but never the feeling of subjectivity itself.
Our experience of consciousness is itself a model created by the mind. It's a simulation of what it would be like for an observer to exist, have a perspective, and reflect on its own state. This makes consciousness a computational, not a magical, phenomenon.
In a reality where spacetime is not fundamental, physical objects like neurons are merely "rendered" upon observation. Therefore, neurons cannot be the fundamental creator of consciousness because they don't exist independently until an observer interacts with them.
The debate over AI consciousness isn't just because models mimic human conversation. Researchers are uncertain because the way LLMs process information is structurally similar enough to the human brain that it raises plausible scientific questions about shared properties like subjective experience.
The simulation of space-time and its physical laws are not arbitrary; they are essential constraints. These rules create the context required for consciousness to explore its possibilities and for subjective experiences (qualia) to become meaningful. Without limitations, there is no context for feeling.
For centuries, we've assumed high intelligence implies consciousness, will, and subjectivity. AI models, which can pass the bar exam but have no inner experience, shatter this assumption. This decouples intelligence from personhood, forcing us to re-evaluate what we truly value.
The "filter thesis" suggests the brain doesn't generate consciousness but acts as a reducing valve for a broader reality. This explains why psychedelics, trauma, or near-death experiences—states of disrupted brain activity—can lead to heightened consciousness. The filter is weakened, allowing more of reality to pour in.
When we observe neurons, we are not seeing the true substrate of thought. Instead, we are seeing our 'headset's' symbolic representation of the complex conscious agent dynamics that are responsible for creating our interface in the first place.
A key tension in studying consciousness is identified. Cognitive science often starts atomistically, asking how disparate sensory inputs (color, shape) are "bound" together. This contrasts with William James's phenomenological claim that experience is *already* holistic, and that breaking it into components is an artificial, post-hoc analysis.
The critique "simulating a rainstorm doesn't make anything wet" is central to the debate on digital consciousness. The key question is whether consciousness is a physical property of biological matter (like wetness) or a computational process (like navigation). If it's a process, simulating it creates it.
Neuroscientists initially believed that identifying the 'neural correlates of consciousness' would explain it. However, researchers like Christoph Koch realized that even finding the exact neurons responsible for experience only answers 'where' it happens, not 'how' or 'why' physical matter creates subjective feeling.
