@Ulrich. Brain doesn't exist. "Brain" is just an idea in consciousness. There are no such things as "best universities". They are all religions. And religions have 0 value. Trying to replicate "the brain" is like trying to replicate a shadow and then wondering why it doesn't work like in reality. Because what animates the shadow comes from outside the shadow.
