If the computational hypothesis for minds and brains is true, and it is only conjecture though a tempting one, I can only see one way out. Analogies are a wicked thing to indulge in here. But bear with me.
If an engineer designs a computer that computes on encrypted information, from an observer's naive perspective, the entire contents of memory is rewritten with a random value for each step. Yet there is a mathematical relationship between those seemingly random bits and whatever is encoded. Even just using some error correction and non-deterministic parallel processing and it might look pretty much like noise if you don't have the decoder ring.
Something like that is the only explanation I can come up with. Information is stored at a level of abstraction in a structure that is maintained by being continuously re-encoded in the ephemeral computations at a lower level.
- michaelerule 5y agoIf I understood correctly, I think I agree with your loose analogy. I've tried combining some error correction with ongoing re-learning. It stabilizes things against drift, but not indefinitely. This is all in an extremely preliminary cartoon sketch of a model. https://www.biorxiv.org/content/10.1101/2021.03.08.433413v1.abstract https://www.biorxiv.org/content/10.1101/2021.03.08.433413v1....
