We have a dual search loop - outside, we act using our experience to gain new data. Inside, we compress this data and update our experience. We search for experience and search for understanding. Acting is search for new insights, learning is search for error minimization.

I think the way we encode our experiences is relationally, like neural networks. We relate new experiences against past experiences, this creates a semantic space that is highly dimensional. Any concept is a point or a region in this space. It has consistent semantics, which leads to the unified experience. We can relate anything to anything in this space without having a central understander. Encoding your own experiences creates a first person perspective from 3rd person data, which was always a "hard" problem to explain in philosophy.

The serial action bottleneck adds to the illusion of centralization. But it's still a distributed process, no neuron is conscious or understands by itself. And even in society, no human can recreate even a 1% of human culture individually. We are not that smart on our own. We should always look for the larger context where we develop, not just the brain.

Search has the virtue of not hiding the environment, it is social and distributed, unlike more personal concepts like consciousness, intelligence and understanding. But as I said above, even inside the brain there is nothing but distributed processing, no homunculus.

I think the core of my argument is "there is no centralized consciousness, understanding or intelligence, they are distributed processes, they act across neurons in the brain and across people in society". It seems like a hard pill to swallow, if that is true then there is also no centralized understanding or truth.
