Dieser Forscher möchte Ihr Gehirn nach und nach ersetzen. Die US-Regierung hat gerade einen Forscher eingestellt, der glaubt, dass wir das Altern mit frisch geklonten Körpern und Gehirn-Updates bekämpfen können.

>A US agency pursuing moonshot health breakthroughs has hired a researcher advocating an extremely radical plan for defeating death.
>His idea? Replace your body parts. All of them. Even your brain.
>Jean Hébert, a new hire with the US Advanced Projects Agency for Health (ARPA-H), is expected to lead a major new initiative around “functional brain tissue replacement,” the idea of adding youthful tissue to people’s brains.
>President Joe Biden created ARPA-H in 2022, as an agency within the Department of Health and Human Services, to pursue what he called “bold, urgent innovation” with transformative potential.
>The brain renewal concept could have applications such as treating stroke victims, who lose areas of brain function. But Hébert, a biologist at the Albert Einstein school of medicine, has most often proposed total brain replacement, along with replacing other parts of our anatomy, as the only plausible means of avoiding death from old age.
>As he described in his 2020 book, Replacing Aging, Hébert thinks that to live indefinitely people must find a way to substitute all their body parts with young ones, much like a high-mileage car is kept going with new struts and spark plugs.
>The idea has a halo of plausibility since there are already liver transplants and titanium hips, artificial corneas and substitute heart valves. The trickiest part is your brain. That ages, too, shrinking dramatically in old age. But you don’t want to swap it out for another—because it is you.
>And that’s where Hébert’s research comes in. He’s been exploring ways to “progressively” replace a brain by adding bits of youthful tissue made in a lab. The process would have to be done slowly enough, in steps, that your brain could adapt, relocating memories and your self-identity.
I’d be more comfortable with the idea of the old neurons and the tissue or cybernetic replacement working in parallel, generating identical signals, before the old stuff is retired. That way there’s no interruption of what is being passed to the rest of the brain.
Imagine if they succeed, and then suddenly all the top 1% starts super caring about the future of the planet, because now they will be alive to witness it themselves
Altered Carbon. This is literally the story. It does not end well for the poor.
I dont see any risk to this at all. Especially when folks start getting the deluxe upgrades.
A Digital Twins collects data from your Life and put on the Internet is good enough… Rest in Peace is a reward for yourself and everyone around you 🤖
So, ship of Theseus, its honestly the only way I think prolonging your life with prosthetics can work. Otherwise, you are just creating a snapshot of yourself in a totally different entity because you break the continuum of your own existence (I’d argue that if you could model your existence as a mathematical function, copying would create a point where, x or time is undefined). To take it one step further, if you made multiple copies of yourself in multiple new bodies, who would be the next you? They can’t all be.
I guess the question then is, how much can you replace at a time and still preserve your sense of self. The difficulty in determining this is maybe why evolution figured out that neurogenesis has to be a bit more selective.
People of Theseus.
The body (except neurons and select others) already does this at the cellular level. Artificially perfecting this natural process might be possible.
Can I make a small adjustment to my cloned body and have XX chromosomes please.
