The full journal article says “in vivo” not “in vitro”. They have already successfully regenerated mice which are organisms biologically similar to humans.

Edit

I was wrong about this. The journal article does only talk about results obtained “in vitro” but mentions other studies that have successfully reversed cellular ageing “in vivo”.

The ability of the Yamanaka factors to erase cellular identity raised a key question: is it possible to reverse cellular aging in vivo without causing uncontrolled cell growth and tumorigenesis? Initially, it didn’t seem so, as mice died within two days of expressing OSKM. But work by the Belmonte lab, our lab, and others have confirmed that it is possible to safely improve the function of tissues in vivo by pulsing OSKM expression [22, 23] or by continuously expressing only OSK, leaving out the oncogene c-MYC

So in this study the results were only in vitro but other studies have successfully reversed cellular ageing in vivo.

Yet so many upvotes :/

Worry? I’m excited for it man.

They don’t realize they’re messing with a monkeys paw.

The first gen lifers are gonna live to regret their discovery.

The only upside I can think of is they’d actually start caring about the planet instead of thinking they’ll be dead in 100 years anyway.

I see one potential good thing though: maybe people would be less interested in killing the only planet that supports human life if they knew they were going to be on it forever.

Don’t worry we’ll live forever too since now we won’t have to retire

Yeah, check out Altered Carbon (the first book or the first season) for how this would likely play out.

Jokes aside, are we just cribbing from sci-fi cart blânche these days?! I mean, sure “Art imitates Life imitates Art”, but still. When the only dead are the poors (>99% of humanity itself), the entire species will certainly collapse. (Where’s the “bridge of nose pinch + sigh” emoji when you need it?) 🤷🏼‍♂️

I guess this is the future that will come sooner or later…

Btw if someone doubts about it - it’s already happening. Here is the example.

This is the such a silver lining take I never would have thought of. Well done.

No they won’t. The answer remains hard vore.

I honestly don’t think so. I don’t think they care of the condition worsen, including theirs as long as they stay above the poorer people.

Like, if we look at the living condition of a medieval era king. You live in a stone castle do your bedroom as freezing temperature in winter, terrible healthcare so you might be in terrible pain for things that easily treatable, no hygiene the smells everywhere must be horrible… Compared with the comfort of a normal person in a developed country. ( Not the US though, now like Denmark or Switzerland) the modern life is clearly way more comfortable.

However I suspect that a lot of people, especially richer people would prefer to be the king, despite the conditions.

If this take is anything like whales with stock they’ll just jump ship onto the next country/planet to start over it’s a never ending cycle

A lot of the rich/ultra wealthy are selfish and don’t give a fuck unless it directly affects them so I don’t foresee any accountability if the planet Implodes instead they’ll just fling their money at the next thing that buys them a ticket out of here

“Thus, rejuvenation by age reversal can be achieved, not only by genetic, but also chemical means.”

It already is

Thanks for reminding me to prioritize the capacity for dignified exit from the game.

Let me start by saying that I haven’t read the article or the study, but I would be very suspicious that this could stop, slow, delay or reverse cancer. In fact, I would guess that it would actually cause more cancer. I hope I’m wrong.

We would also have to consider the impact of people living longer would have on the environment. People will still be having kids, and if you were going to live longer you might want to have many more kids while you’re young. Our rock is going to get pretty crowded really fast if people stop dying of old age.

Then there’s the point about people still being ‘productive’ to society. Honestly, if I’m going to live longer, I don’t want it to be so I can continue to be productive. I don’t like being productive as it is. I’d prefer that humanity focus first on fixing our economy before trying to extend our lives.

Despite appearances, I’m not trying to argue with you for the sake of argument, but more just putting other ideas out there to consider. I do hope your vision is right, and this will be something available to everyone and helps to make our final years more pleasant.

I would think suddenly being able to go back to your 20s is the NG+.

Good thing you brought us a bunch of useful information with you from the other side.

It’s not a path to living forever; cells can’t reproduce once they burn through their telemeres. What this is is a way to have a youthful body at an older age so you won’t spend the last years of your life frail and wrinkly

I doubt that will be the reality of any such breakthroughs, at least not for a long time. But I think the solution in such a scenario would have to be sterilization of everyone on earth by default. Sterilization which could be temporarily reversed to allow someone to have a child via a controlled application process just to meet the rate of replacement.

I doubt it works on anything but skin cells.

We could start by giving it to congress
