Aaaand the ultimate question: if electric fields are controlling the neurons, what (or who?) contols the electric fields?
The illusion of a stable single entity emergent from the constant flux of billions of individual living units linked through trillions of connections is in my opinion the answer to the question of consciousness (and also an answer to the question 'can machines ever be conscious', which is without a doubt - yes).
It might also pose the question then, could humanity as a whole - as a global connection of billions of individuals - be thought of as a conscious entity? Well, maybe not - where's the stable field?
