My question as a non-science non-tech sort of person;
If they use the brains of people who have terminal illnesses and are six months away from death, won’t those brains be in poor condition too? Why revive a brain that is slowing down in many of it’s major functions, or has already stopped certain functions completely? The brain stems are likely to be providing reduced nourishment for the lobal regions.
I think it is just to retrieve what you can as once in the computer there will be all the nourishment one needs as long as there is enough electricity.
