The prospect of people coming back from the dead has come a step closer?

I'm not squeamish, but I do find this report quite troubling -
very interesting, but the possible implications are scary ...
Well, it does raise questions about "the soul", doesn't it? Just as Alzheimer's does. Just as prion diseases do.
Human cells have been added to mouse brains. What does that mean?
In fact, some people have themselves frozen (Ted Williams of the 1940-50's Boston Red Sox, for example) in the hope of being "revived" when medical science can "cure" what killed them.
OK, but isn't a brain all about connections and their history and their supporting environment? Reviving a few cells won't restore that.
I read a novel in German--I forget the title and the author--in college about two guys who switched heads. The result wasn't the sum of the parts. The athletic guy got fat and somewhat lazy. The more intelligent guy changed too. In fact, people change over time without "human" intervention. Gut bacteria, exercise, disease, life experiences (DNA can be "methylated based on stress and affect what happens in the body and which genes are expressed, there is PTSD, there are concussions) all influence the brain and its "personality".
Connections are so complex that it is unlikely we'll ever be able to sort it all out and engineer it. The best we can do is "Brave New World" stuff, where we change people's circumstances and mess with their lives. That's bad, of course, but it's not total control.
This Easter, one can ask whether people WANT to come back from the dead. For all we know, Christ's reaction was "Woo, hoo, I'm finally out of there!")
Sorry, you shouldn't give me an opening like that. You get an essay. It's worse sometimes than firing up Richard Dawkins. "Deep" philosophy tends to annoy me. I like data--the soul of an engineer.
