At best, they could induce a new brain to grow in that body. That would make a new person. Depending on the source of the stem cells, that new person would be dramatically different. Plus, uneducated. There is a strong moral component to placing a new person in an old body--I'd call it extremely unethical. Then there is the practical component that this person would need to be educated--who wants to deal with an infant in an adult body, with all of the emotional outbursts and so forth?
Maybe for purposes of repairing badly damaged brains where the original person is still present--like Terri Schindler--this technique would have applications. We would still have to reeducate the person, and they would not be the same as prior to the injury. But replacing dead brains? I don't think we want to go there.
How do you know Terri was her original person. I’m sure most close to her would have disagreed.
i’ve known people ravaged by brain damage and they are not their “original person”
She should never have been murdered but your argument isn’t strong.
