There’s another interesting question related to this one which has to do with creating a gene edited clone of yourself.
If we can make an embryo from one of your stem cells, we could potentially do substantial editing of it to enhance it in various ways (perhaps to reduce disease risk or increase intelligence).
How many edits would one need to make before it is no longer really a clone of you?
What if instead we grew a genetically enhanced replacement body for you with no knee issues and better cardiovascular performance? Are you still you with a new body?
There are all kinds of interesting questions that arise with sufficiently powerful biotech. Most people don’t spend much time thining about them because the tech to make them relevant is a ways off.
Hijacking this to pick your brain. 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. Related to this, do you think parabiosis would work without all the body switching? I don’t know if this is in your wheelhouse exactly but you mentioned mentioned a replacement body and this has been on my mind for a while.

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.

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.
