Good lord, just let people DIE. Imagine what a rotten place this would be if people with outdated mindsets continued to control the world decades or even centuries after their expiration dates. People were already angry about 80 year old presidential candidates… what happens when they’re 120, or 150?
For $10 a month you can get the brain implant without ads.
You know… I’m just gonna check this DNR box.
I’d rather not enact the highest stakes ship of Theseus
Probably the best description I’ve seen of this lmao
You don’t want to save your old brain chunks and put them back together to see if you can make on old version of you?
I’m in, lets do this
FROM THE MOMENT I UNDERSTOOD THE WEAKNESS OF MY FLESH IT DISGUSTED ME
There are two reasons he believes the neocortex could be replaced, albeit only slowly. The first is evidence from rare cases of benign brain tumors, like a man described in the medical literature who developed a growth the size of an orange. Yet because it grew very slowly, the man’s brain was able to adjust, shifting memories elsewhere, and his behavior and speech never seemed to change—even when the tumor was removed.
That’s proof, Hébert thinks, that replacing the neocortex little by little could be achieved “without losing the information encoded in it” such as a person’s self-identity.
The second source of hope, he says, is experiments showing that fetal-stage cells can survive, and even function, when transplanted into the brains of adults. For instance, medical tests underway are showing that young neurons can integrate into the brains of people who have epilepsy and stop their seizures.
“It was these two things together—the plastic nature of brains and the ability to add new tissue—that, to me, were like, ‘Ah, now there has got to be a way,’” says Hébert.
Very interesting. I’ve also seen research suggesting that the application of stem cells to damaged neural tissue within the spinal cord could repair it, so the idea that you could use a similar approach to actual brain health isn’t such a big leap. But still, wow. I wonder how long it would take for the immature cells to develop into “adult mode” that’s fully integrated into the patients cortex. In order to replace the entire brain, you’d have to do it in like, 8 parts, with years of recovery time in between each surgery. Also there would exist the potential for the new cells to develop into like, a second, smaller brain, if the connections sour or if the new material isn’t stimulated the “right” way.

Wow, that’s wild.
The brain renewal concept could have applications such as treating stroke victims
If this can restore functions to stroke victims again, it’s absolutely amazing.
If this is vastly successful which remains to be seen, there might be a path format to the longevity part of the idea.This could help a lot of veterans and football players too
I can think of a lot of football players who are in need of more brain.
CTE.
I mean, they were in need of more brain before the CTE too
Happy cake day!
This is the correct way IMO. “Uploading” your mind to a computer is making a clone/copy, but the original dies the same.
Maintaining continuity of consciousness is the only thing that would make me feel comfortable with converting myself to a machine intelligence.
I hate to break it to you, but our meat brains don’t even have continuity of consciousness. We become unconscious all the time. The only real constant is the “hardware” our consciousness emerges from, but even that is always changing.
I don’t get the down votes. Did y’all forget about sleep? No one vividly dreams every night all night long. Often it’s the fade to black going to sleep then the sudden awakening.
You do not die every night.
Obviously not, but what is the functional difference? If you can’t tell it’s happening, does it actually matter?
Yes, yes it matters a lot. If you die you do not wake up again.
Sorry, should have been more specific. If you died in your sleep every night and came back to life in the morning, and you couldn’t tell it was happening, would it matter?
It’s not a question with a right answer, I just want to hear your thoughts about it
I agree.
But here is an interesting thing to think about:
What is the perceived difference between falling asleep and waking up the next day, vs going to sleep and copying your consciousness to a machine/new body.
The body. It’s feeding you vast amounts of information every moment, it’s the one making decisions, you’re the AI assistant providing analysis and advice
If you clone a tree, you get a similar tree. The branches aren’t in the same place. If you clone a human, why would the nerves be laid out the same way? Even if it’s wired up correctly, without a lifetime of cooperation why would your body take your advice?
Imagine you wake up. Red looks blue. Everything feels numb. The doctor says “everything looks good, why don’t you try to stand up?”. You want to cooperate with the doctor, but you don’t stand up. You could move, but you don’t. Rationalizing your choices, you tell the doctor you don’t feel like it. You feel your toes, you shift to get away from the prodding of your doctor, but you just can’t muster the will to stand
Imagine you wake up. Your sight is crystal clear, you feel your body like never before. The doctor says “don’t move yet”. With the self control of a child, you rip out the itchy IV to get the tape off of you. The doctor says something in a stem tone, and you’re filled with rage. You pummel the doctor, then are filled with regret and start to cry
Emerging science suggests this kind of situation could lead to brand new forms of existential horror
The doctor says something in a stem tone
[email protected] moment?
The m in stem stands for medicine. Maybe your new body doesn’t trust experts, so when doc spoke in an overly educated tone it provoked aggression. Possibly because of overhearing this tone during incubation and while getting the original brain replaced
Or maybe I made a typo
Your brain is still functioning while you’re asleep. If it turned off all the way then you’d become brain-dead.
That continuity of function is arbitrary. In reality it provides people comfort in some idea of a soul but there’s nothing suggesting it actually provides anything to the continuity of consciousness.
Between every loss in time, where you stop forming memories until you wake up again, you have nothing to affirm that your current consciousness is the same as your last waking period’s. The only thing vaguely providing that illusion is your previously-formed memories, which would exist all the same on the digital mind, in theory.
I don’t think you understand. Your consciousness is just one process amid a myriad of processes that your brain runs. It’s that continuity that matters. You’re correct that I don’t know if my current consciousness is the same as prior consciousnesses, however what matters is that my brain has never shut off, giving me the feeling as though I am the same person; and it is because of that thread that I am the same person (though perhaps with a different consciousness).
Furthermore, you can’t achieve immortality through digital consciousness if you just copy the whole thing and throw out the original. Again, it’s the continuity. It honestly confuses me why people think that’s a rational idea when the very obvious problem is, “what if something goes wrong and human me wakes up?”
That’s why you have people, like me, who get frustrated when people start getting philosophical about this shit because they think you can “just make a perfect copy” of a person to achieve immortality.
Seriously?
No.
You just killed yourself and made a copy of yourself. You didn’t achieve shit. Your new self might be happy, but your old self is dead. You’re not suddenly going to wake up as a digital clone. You’re not waking up at all, it’s your clone that’s waking up.
And hey, if that’s good enough for you, then so be it. Just don’t pretend you’ve achieved immortality; it was your digital clone that did. You’re still going to die.
It also confuses me that so many people seem to believe that you’re literally brain-dead while you sleep. If you were literally brain-dead then there’d be no way for you to wake up. Sleep seems to be when the brain processes memories too, so if your brain fully shut off, then it wouldn’t be able to processes memories while you’re asleep. Finally, afaik, once the brain shuts off, it can’t turn back on; evolution didn’t plan for a situation in which someone’s been dead long enough for brain activity to cease before their heart starts pumping again. So why does everyone insist that you go brain-dead the moment your head touches the pillow?
This convo has gone on for centuries at this point. The Brain in the Jar, the teleportation conundrum, Thesius’ ship, it’s all already been covered over and over. people like you still keep crawling out of the woodwork thinking you know better than every philosopher that already waxed over this problem ad nauseum.
Your ‘continuous self’ is just as worthless as a concept. The idea that your ‘sense of being the same person’ is being held together by being apart of your plumbing just as much of an illusion. It’s worthless.
To elaborate, you are not the brain. You are the observer, the thing which exists as a byproduct of the brain’s processes, perhaps even a process yourself within. There’s also plenty of times when you will lose time other than sleep, like concussions, getting blackout drunk, panic attacks, and after those times you have no memory of making decisions or acting in your own accord, but you were. You, the observer, were absent while the brain kept working. So where were you?
You act as though you’re sure you are still the same observer as the one who went to bed. That is completely unsubstantiated. You may have just been born into your body when you awoke today, and will only have until your body falls back asleep again before you cease to exist, replaced by another process that thinks itself is you, another observer.
And if ‘you’ one day woke up in a digital world, like our own, it’s you’d be none the wiser, because your self is simply a collection of processes and memories. It’s arbitrary. It’s all dust. There’s not some special ‘continuity’ that keeps you alive somehow.
But would you notice?
You wouldn’t notice because you’d be dead. Your clone wouldn’t notice because it would think it was you. Your friends and family wouldn’t notice because they’d think your clone was you.
Millennials and Gen Z: *bond over their death wish Scientists: *ETERNAL LIFE
Could they have at least waited for the boomers to go first, they’ll never give up power now
Brain of Theseus.
I don’t want to live longer, fix my fucking knees and back.
Ya the SENS repair approach is the way to go IMO.
If they make it so I can eat cheese and go outside in summer without drying I’ll happy
Yes, please focus on the Global Dryness problem first. I must be wet at all times.
As long as it’s made mandatory to cover with insurance so it’s available to everyone. The last thing we need is an immortal ruling class.
Hoping real hard that Alternate Carbon is not becoming reality.
Don’t worry, going by past history this will be available to any and…uhh, [checks notes] oh, uh-oh.
Oh at this point it seems like we’re treating dystopian science fiction as a guidebook instead of a warning.
Sci-Fi Author: In my book I invented the Torment Nexus as a cautionary tale Tech
Company: At long last, we have created the Torment Nexus from classic sci-fi novel Don’t Create The Torment Nexus
On the plus side an immortal ruling class might actually start caring about climate change.
Is a forever expanding population of old people much better?
If they’re functional, and we get serious about space or birth control, then no it’s not a problem. But that is another path we can take to really juice the dystopia.
It will take a very long time indeed before we can reach another habitable planet enough to alleviate an exponentially growing population, and forced birth control will be unpopular, not to mention probably employed as eugenics by those in power against those who aren’t.
There’s always orbital habitats. They ramp up a lot quicker than even a Mars colony.
Not the way I’d want to spend the rest of my life, that’s for sure.
Eh, it would be worth it with the right recreational activities up there and knowing we weren’t setting up altered carbon.
You’d have zero control over your existence. Someone else would own that station and you’d exist entirely at their whim. They would decide if you get food, air, water, shelter. No real access to nature. I’d rather die.
this might finally be a way to eliminate insurance companies
So we get Universal healthcare then, right?
right?
they tried that a few years back via a quadraplegics brain transplant to a normal body. he died on the table. not likely to change that with cloning
I’ve just looked it up and there has never been a full brain transplant, so I don’t know what you’re on about.
They might have confused it for a head transplant?
Although neither patient was alive at the time of the transplant.
I don’t know if a full brain transplant would be feasible, or even a good idea. Not only would none of their senses and motor nerves work for weeks while the brain and nerves re-established themselves, but they would be walking around in a dead person’s face, body and speaking with their voice. That seems genuinely horrific.
Why not?
go look at images of old telephone wiring like when POTS was still the main method.multiply those rats nests of wires by a billion and shrink that them down to the molecular size and you might see the issue
I cut a big nerve in my thumb years ago, and apparently plastic surgeons fix that sort of thing.
They reattached the nerve bundles, but I was told the sheathes could be realigned, but the nerves would have to grow back from the point of the cut all the way to the skin.
At first one half of my thumb was entirely numb, and over the course of well over a decade I’d get pins & needles as bunches of nerves would finish regrowing, except attached to random channels in the nerve bundle, so my brain had to completely remap all those signals to what they actually meant. Also extreme nerve pain near the cut whenever it was bumped, I assume because many nerves just didn’t grow successfully and remained near that site.
It felt super weird because hot, cold, pain & touch were all mixed up, but eventually my brain sorted them out. It still feels a little weird, especially near my nail, but I haven’t had a pins & needles experience for a few years.
The problem with doing that with a neck is that it would take wayyy longer and the chances of the patient dying from complications due to no brain signals working right… yeah I don’t see medical science fixing this unless we can regrow nerves in a much shorter span of time.

Wow, that’s fascinating. Thanks for sharing your story.
Thanks! As far as I know I’m not describing anything too unusual with the mixed-up signals, I think pins & needles is essentially that, just a bunch of nerves randomly firing, so you probably do know what it’s like in little doses.
I’ve been paying attention to it since I wrote that, and it definitely is still slightly more numb on the affected side, I think I was right that not all the nerves regrew completely.
I want a brain update and a penis upgrade please! Yes 275Tb of ram for my penis and 6" of brain 🧠!
I don’t want my penis remembering that much.
The penis upgrade already exists, it’s called a “vaginoplasty,” sweaty 💅💅💅
Yes, because who wouldn’t want to live for centuries amidst floods, fire, raging mad politicians and greedy billionaires…
Well this really exists for those billionaires and rulers. This isn’t for the common person.
They’re so mad that they’ve removed themselves so far from us and we still share a common experience in death. That’s unfair for them to have to be associated with peasants in such a debasing way. So now they’ll remind us that death is for the poor or at least not living centuries will be for poor.
Somebody’s been watching Picard.
I’m a transhumanist, and I’ve never heard of Picard in the context of something you watch, and what’s being spoken of in the article is something that’s been part of our wider Philosophy for longer than I have.
Picard swapped his brain into an android body. It wasn’t very good writing.
