The ASTRONOMICALLY MASSIVE ethical issues aside, scientifically and medically speaking, this is pure lunacy.<p>&quot;Organ&quot; rejection is going to be a huge problem here, as you have the head&#x27;s immune response fighting with the body&#x27;s and no previous research has been shown that one will win over the other.<p>The surgeon has done this on 2 monkey models and there is not yet a long term history of the procedure. There are no verification studies by other groups, AFAIK, that prove his methods work. There are no measures of the health of the monkey in the long term. I believe that the monkeys were all healthy and diseased like the human cases.<p>Where is the body donor coming from and in what state is that corpse relative to surgery? Was it in an automotive accident 2 hours ago? Too many variables here.<p>Small monkeys are one thing to freeze down, but a human head is another. Maybe try this on pigs first and see, as their vascular system is comparable in size to ours and they have will be a good extreme case for eating issues and infections that the person will encounter.<p>What in the everliving hell kind of surgery suite is this going to be?! Holy mother if it is not going to be the most expensive operation in history. The chaos in trying to get all those people in there and in the right places at the right times itself will need to be practiced for months if not a year. Again, porcine models will help with that.<p>Now, the science aside. The ethical issues are astounding and not easily dismissed. The artificial heart changed our perception of ourselves as what it meant to be human, and if this goes through, this will be just as challenging to our ideas of a human as well. That said, the surgeon sounds like a nut bag that has been writing himself too many painkillers or something. I&#x27;d never want this guy to operate on me.
