Re: Well
Two mistakes. One that we are not the same as what we are made of. And two that we need a human brain for any of those tasks.
As it would have the same structure as a person, a reanimated brain would be a person. No excaping that.
As we only need neurons, we can use any type (fish, worm, Z list celebrity) to do our calculating. Why choose the most risky and hardest to keep functioning?
