Do you think head transplants on to repeatedly cloned bodies could work as life extension? Even without genetic improvements to increase longevity, I can imagine switching bodies every 20-50 years becoming mundane with nearly modern surgical techniques provided we can reconnect the nervous system.
Yes, I think head transplants could extend lifespan pretty significantly if you can do them safely (they’re currently super dangerous), but I don’t think it would extend lifespan indefinitely. The brain itself ages, so unless you have a means of gradually replacing brain tissue a la Jean Hebert, you’re not going to get to indefinite lifespan extension.
Related to this, do you think parabiosis would work without all the body switching?
I mean… would you WANT your circulatory system hooked up to that of someone else? Sounds gross, weird and extremely inconvenient to me, even if you’re the one benefitting.
I can see blood transfusions if you can make artificial blood. But I can’t see parabiosis ever being a thing unless it’s in some exceptional circumstances.
It’s not that I want to be fully conjoined with another person, so much as I might prefer that to death in the medium term to get me over the hump to longevity escape velocity. Also, I kind of always imagined it more like a dialysis machine. We don’t grow a whole person so much as a big pile of organs sans brain that is genetically you (or just compatible enough to not cause rejection issues) and get hooked up to that for a while. Maybe medically induce a coma for a few months out of the year, maybe it will be quick and easy to connect/disconnect and you can be plugged in while sleeping or doing desk work. People always object to my life support clone/flesh pile idea but again, better than dying imo.
