Extending the simulation theory, cognitive scientist Donald Hoffman argues that your physical components, like neurons, do not exist persistently. They are rendered into existence only in the moment of perception by an observer. If a neuroscientist observes your brain, the neurons exist in their perception, but they were never 'your' neurons in an objective, independent sense.
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.
Hoffman's theory posits that our perceived world is not a persistent, objective reality but a simulation that is rendered only when an observer looks at it. According to this model, when you look away from an object, it ceases to exist and is only re-rendered upon observation.
With 10x more neurons going to the eye than from it, the brain actively predicts reality and uses sensory input primarily to correct errors. This explains phantom sensations, like feeling a stair that isn't there, where the brain's simulation briefly overrides sensory fact.
According to Hoffman's theory, what lies 'outside the headset' of our perception is not physical. Instead, the fundamental layer of reality consists of a network of interacting observers or 'conscious agents.' These can be described mathematically (as Markov chains), and our perceived physical world, including spacetime, is a projection generated by their interactions.
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.
The Nobel Prize-winning discovery that the universe is not locally real suggests it operates like a video game engine, rendering reality only when an interaction or measurement occurs. This principle of computational efficiency, along with the universe having a minimum pixel size (Planck scale) and tick speed, strongly supports the simulation metaphor for reality.
Cognitive scientist Donald Hoffman argues that spacetime and physical objects are a "headset" or VR game, like Grand Theft Auto. This interface evolved to help us survive by hiding overwhelming complexity, not to show us objective truth. Our scientific theories have only studied this interface, not reality itself.
Dr. Levin speculates that physical reality is constrained by truths from a mathematical or "Platonic" space. He extends this to propose that minds themselves are patterns in this space, and our bodies are temporary physical projections or "thin clients"—interfaces through which these non-physical patterns act.
Hoffman's model proposes that consciousness is not a product of the physical brain within space-time. Instead, consciousness is the fundamental building block of all existence, and space-time itself is an emergent phenomenon—a "headset" or user interface—that is created by and within consciousness.
