Here’s a LWer suggesting the key to life extension is to grow unconscious clones of yourself and when your current body becomes too old, just pop your brain into the clone

please enjoy picking apart this idea, b/c so far the LW commentariat aren’t interested

Imagine it like this: a baby version of yourself with only enough of a brain structure to be alive in case you ever need a new kidney or liver.

Or, alternatively, he has speculated, you might one day get your brain placed into a younger clone. That could be a way to gain a second lifespan through a still hypothetical procedure known as a body transplant.

The fuller context of R3’s proposals, as well as activities of another stealth startup with related goals, have not previously been reported. They’ve been kept secret by a circle of extreme life-extension proponents who fear that their plans for immortality could be derailed by clickbait headlines and public backlash.

And that’s because the idea can sound like something straight from a creepy science fiction film. One person who heard R3’s clone presentation, and spoke on the condition of anonymity, was left reeling by its implications and shaken by Schloendorn’s enthusiastic delivery. The briefing, this person said, was like a “close encounter of the third kind” with “Dr. Strangelove.”

A key inspiration for Schloendorn is a birth defect in which children are born missing most of their cortical hemispheres; he’s shown people medical scans of these kids’ nearly empty skulls as evidence that a body can live without much of a brain.

And he’s talked about how to grow a clone. Since artificial wombs don’t exist yet, brainless bodies can’t be grown in a lab. So he’s said the first batch of brainless clones would have to be carried by women paid to do the job. In the future, though, one brainless clone could give birth to another.

Last Monday, the same day it announced itself to the world in Wired, R3 sent us a sweeping disavowal of our findings. It said Schloendorn “never made any statement regarding hypothetical ‘non-sentient human clones’ [that] would be carried by surrogates.” The most overarching of these challenges was its insistence that “any allegations of intent or conspiracy to create human clones or humans with brain damage are categorically false.”

My ‘no conspiracy to create humans with brain damage’ shirt is making people ask a lot of questions

This reminds me of the research I’ve read on people with a split brain - people who have gotten their corpus collosum severed in order to treat severe epilepsy and ended up with two independent but functional brains controlling parts of their body or different functions. From what I remember (and I’m too lazy to find and cite a source, so please correct me if I’m wrong) they ended up not only having half of their bodies controlled separately, but some speech functions and communication abilities were also split. So for example, if they saw something with their left eye only they wouldn’t be able to identify it speaking out loud but their left hand would be able to write the name of the item. I almost definitely got the pop science oversimplification of this, but the relevant takeaway is that the human brain is really complicated and resilient. If each half can independently develop the ability to replicate motor functions and some communication and reading/writing, then it seems like at best wishful thinking to assume that it’s possible to consistently engineer a human body that’s just alive enough to keep the biological machinery functioning but not alive enough to merit even the moral consideration of a farm animal.

In turn I’m reminded of House of the Scorpion which tells the story of Matteo Alacrán, who was born and grew up in relative luxury on an opium plantation staffed by neurologically neutered slaves, including clones. Matteo himself is eventually revealed to be the latest clone of the patriarch of this whole enterprise and the decision to let him actually live a good life up until it’s time to kill him and take his organs is a kind of twisted kindness on his part. But compared to the actual rationalist plan, the Alacrán method at least treats everyone like a disposable resource used to further the goals and whims of the ruling sociopath. Matteo is treated as a person, is what I’m saying. Congratulations to the life extension weirdos for making the sociopathic drug lord ruler of a literal YA dystopia novel seem like they have an actual point.
