Startup Pitches 'Brainless Clones' To Serve the Role of Backup Human Bodies (technologyreview.com) 163

MIT Technology Review discovered that startup R3 Bio has pitched an ethically and scientifically explosive long-term vision beyond its public work on non-sentient monkey "organ sacks": creating human "brainless clones" or replacement bodies for organs as part of an extreme life-extension agenda. From the report: 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 [R3 founder John Schloendorn's] enthusiastic delivery. The briefing, this person said, was like a "close encounter of the third kind" with "Dr. Strangelove." [...]

MIT Technology Review found no evidence that R3 has cloned anyone, or even any animal bigger than a rodent. What we did find were documents, additional meeting agendas, and other sources outlining a technical road map for what R3 called "body replacement cloning" in a 2023 letter to supporters. That road map involved improvements to the cloning process and genetic wiring diagrams for how to create animals without complete brains. A main purpose of the fundraising, investors say, was to support efforts to try these techniques in monkeys from a base in the Caribbean. That offered a path to a nearer-term business plan for more ethical medical experiments and toxicology testing -- if the company could develop what it now calls monkey "organ sacks." However, this work would clearly inform any possible human version.

          Frankly, I think your take on this IS the concern. It would be a near immediate upheaval of society, with those that can obtain it amassing great power over time, and population controls being needed once fewer people are dying.

          As a side note, Cory Doctorow's Down And Out In Magic Kingdom and Walkaway both touch on some of these pseudo-immortal people in a very interesting way. Both books are terrific and even hold up to multiple readings.

    I'd love to have a nice slab of spare parts, custom made for me in case of injury.

    You'd have to fight back the idiots who would claim the bodies had souls. That's probably the biggest hurdle, the people who would violently try to stop you because of their sky daddy fantasy.

    But even if you defeat them, you have the accountants. That spare body isn't going to grow and remain healthy without a lot of effort. It will need to be fed and cleaned and exercised. During growth it will need to be monitored and probably adjusted with chemical cocktails to ensure it turns out similarly to you - you did want all the bones to be the same size as yours so you can harvest those, right? As long as you're cloning an entire body, you'll want to correct any genetic defects you can - especially for those things that might lead to needing a clone body for spare parts. You don't want to get liver cancer only to find your clone has it too. That's all going to cost a lot of money.

    In the end, the real solution is to be able to grow parts as they're needed, not grow an entire body requiring expensive maintenance that you might have to throw away after you harvest one critical part.

      This is one case where the sky daddy freaks could be useful to stop an extremely dangerously stupid move "forward." Because we live in this world, in this time, if this goes forward, it will 100% be used to extend the lives of the ultra-rich, while the rest of us remain fodder for their machinations. People want to believe these types of advances would be useful to the majority, but in this reality, here on Earth early in the 21st century A.D. it will absolutely be the playground for those who would like to term themselves God Emperors for Eternity. Think if Donald Trump and Vlad Putin's brains could be placed into younger bodies. Think how much damage they could cause when they never have the opportunity to die.

      Aside from that, living forever doesn't sound like all that great a deal in this existence. We're already talking about moving the retirement age out further, as our life expectancy continues to drop. If it were possible to live forever, retirement would become another luxury reserved for the ultra-rich, and us normies would simply be stuck working drudge jobs for eternity. No thanks. I'll take my chances on going to sky daddy's Hell or the oblivion I think more likely in death over an eternity working in a job I only care enough about to keep myself and my loved ones taken care of. I don't want an eternity of obligation. Death is rest. Life is responsibility. As much as I like scientific advances, I don't want it taking away my potential to eventually lay down and be done with all this shit.
