>>>Brain doesn't exist. "Brain" is just an idea in consciousness.
Consciousness tries to make sense of our experiences. Our experience is that consciousness runs on a substrate we call “brain”. As model of what we experience it is indeed an idea that exists in consciousness. That doesn’t mean it doesn’t exist. Ideas can exist and can be about things that exist. >>>There are no such things as "best universities". They are all religions. That’s the old and long debunked “science is just another religion” fallacy. >>>And religions have 0 value. That depends on your perspective. What you call value. Values are always personal. >>>Trying to replicate "the brain" is like trying to replicate a shadow and then wondering why it doesn't work like in reality. Well, sort of. Numerical models are never replicas. And they can never fully simulate what they are model of because there are always random events in play (e.g. at the quantum mechanical level) that can by their very nature not be replicated. That’s why true “uploading” can never be achieved. >>>Because what animates the shadow comes from outside the shadow. That’s if you consider a shadow as animated (as opposed to a succession of shadows that that create the illusion of animation). In any case, that analogy only works as long as there is an outside (e.g. it works within the universe, but it doesn’t apply to the universe at large.)
