What's the "best" way to do a Moravec transfer/slow replacement? / story feedback.
In the novel I'm working on, I have two characters that undergo this process via a neural network bridge (ex-vivo transfer?) from the biological neurons in brain A to synthetic in brain B, rather than an in-place replacement. It also allows the characters to change bodies as they upgrade their minds so to speak.
I was under the impression this is the most scientifically grounded method because if performed in-place it would basically cook the biological brain - injecting billions of nanobots inside the same skull - but if performed as a functional bridge, then the original can survive using the same method of neural communication (neuroplasticity) that already exists in our own mind, while spanning it across to the new neurons in a new body.
Here is an example of how one scene is portrayed, the POV seeing it as a kin-of "hallucinated spacial narrative": "The world began to dissolve around Travis as he closed his eyes. He found himself in a tunnel following a stream of light for what seemed like an eternity. It was as though he was moved between two realities as he felt new sensations taking form while others shut down. When the world began to reshape, he slowly opened his eyes, feeling much lighter than before."
As you can see, it's sort of a bottleneck transfer based on what I heard was the "functional" view, opposed to a "materialist" or biological essentialist one, which defines consciousness as being tied to the carbon atoms we were born with, and is sometimes religious in nature.
Have I done a good job at preserving the original person? It's very important for my narrative.
