Afraid I don’t see any of these as problems. Consciousness might be distributed, and this “memory” and “cognitive function” deserve scare quotes.
Not a meaning I’m familiar with, and the intenet doesn’t seem to know about it either. The main point is that an analogy isn’t evidence.
Sure. So why do you reject the one but not the other? And of course we know that the brain exists, but have no evidence for any external source of consciousness.
Well, possibility and support are quite different things, aren’t they?
