Will humans live forever one day?

Humanity has long dreamed of surpassing its biological limits and living longer. What if we could cheat the unalterable approach of aging and physical decline and escape death on our own?

Paul Root Wolpe, director of the Emory Center for Ethics, said: “The quest to live forever, or live in great times, has always been part of the human spirit. Time magazine.

Now there seems to be reason to be optimistic. Over the past century, science and medicine have extended life expectancy, and longevity researchers (not to mention Silicon Valley types) are pushing for a life that lasts at least decades from now,” the magazine said.

But can we really live forever and if so, do we want to?

Here are a few ways that could help us one day reach that goal:

Biomedical technology

Along with the advancements of medicine, scientists have continuously looked at aging as if it were a disease that needs to be cured.

“From strengthening certain proteins that protect cells from aging to lengthening telomeres – segments of DNA that wrap both ends of each chromosome and protect against the wear and tear of the natural aging process – scientists have been trying to stop the aging process.” Journal.

Big tech entrepreneurs, including Amazon’s Jeff Bezos and Facebook’s Mark Zuckerberg, are increasingly interested in finding the secret of eternal life – or at least significantly longer.

Bezos is said to have invested millions of dollars in Altos Labs, a gene discovery project “reprogramming,” a process in which “adult, specialized cells are coaxed into becoming stem cells.” immature cells can become almost any other type of cell,” Time speak.

This would allow cells to be “rejuvenated” and repaired, which could hopefully cure aging diseases and ultimately extend human lifespan.

The venture, also believed to be backed by Russian billionaire Yuri Milner, recently made a famous hire, bringing in Hal Barron, GlaxoSmithKline’s former chief scientific officer, as chief operating officer.

It also has numerous Nobel laureates as advisors and council members, including Dr Shinya Yamanaka, the 2012 Nobel laureate in Physiology or Medicine, and Jennifer Doudna, who shared the prize. chemistry prize 2020.

Meta CEO Mark Zuckerberg and his wife Priscilla Chan are also looking to drop some serious cash to improve human health over the next decade as part of the Chan Zuckerberg Initiative (CZI). This initiative has a mission to cure, prevent or control any epidemic by the end of this century.

The pair plan to spend $3.4 billion on “developing new research, institutes, and technologies that can help their mission,” according to the report. Daily mail. This includes $600 million to $900 million for the biomedical imaging institute at CZI, as well as a billion dollars given to the Chan Zuckerberg Biohub, which develops technologies to treat the disease.

One expert at the forefront of this movement is Martine Rothblatt, founder of the biotech company United Therapeutics, which is looking to grow new organs from human DNA. “Clearly, through technology, it is possible to make death optional,” Rothblatt told New Yorkers.

Another expert, Joon Yun, told Nautilus magazine: “Basically, I bet myself that aging is a code…that can be cracked and hacked.”

In 2014, Yun created the Race Against Time Foundation and the Palo Alto Prize, which will award $1 million (£739,000) to a group of scientists who can demonstrate the ability to reduce minimize aging by extending the lifespan of mammals by 50%.

Cryonics

Perhaps the most famous option in the pursuit of immortality is cryonics. This involves freezing people in liquid nitrogen in the hope that they can one day be safely thawed and revived.

The process is based on “absolute hope that future scientific advances will make it possible to use these dismembered bodies and heads to achieve life after resurrection,” Evil behavior. “Nothing close to a proof of concept exists to date.”

This hasn’t stopped companies from trying it. The most important of these companies, Alcor Life Extension Foundation, pioneered an approach where the brain is removed before death and treated with both cryoprotectants and chemical fixatives.

According to Kenneth Hayworth, a neuroscientist at the Howard Hughes Medical Institute, this is evidence that preserving the brain is “technically feasible,” but he says significant research is still needed. .

“The way that I think these people will be revived is that their minds will be put into the brain and the synthetic body,” he said. Evil behavior.

HowStuffWorks predicts: “Meat and blood are not ideal materials for longevity, so we will switch to a slightly more durable material.”

The singularity and transhumanism

Other experts envision a world in which computers act as backups for our brains and silicone parts replace frail limbs.

AI author Ray Kurzweil claims that in 2045, an event known as a “singularity” will occur. Man will become one with the machine.

The technological singularity, as it’s called, is the moment when artificial intelligence evolves into ‘artificial superintelligence’ and gets exponentially smarter. As self-improvement becomes more efficient, improvement gets faster until machines become infinitely smarter.

At this point, human evolution will be forced to correlate with AI evolution for fear of being left behind.

“In my lifetime, strange things will happen,” says Alison Lowndes, head of AI developer relations at tech company Nvidia. Metro.

Author and journalist Will Self told the newspaper: “We are already in a state of human transformation. Technology happens to people, not humans contributing a part of it”.

Indeed, the body can already be enhanced mechanically, internally or externally, and first microchips have entered the workforce.

But “a little bit of difficulty remains until the technology becomes widely available,” Sun. “Most middle-class people and reasonable working-class income can afford this by the 2060s. So anyone aged 90 or younger by 2060.”

Is there a natural limit to human lifespan?

Not everyone believes we will be able to continue indefinitely. Many researchers believe that there is a limit to the number of years a human can live.

“Aging is mathematically inevitable,” said Joanna Masel, a professor at the University of Arizona. Like, seriously inevitable. “Masel’s .” search suggests that by addressing aging, other problems will become worse.

“You will always be stuck with old, sluggish cells that push you closer to the grave, or extremely powerful cancer cells that do the same thing.” New York Post.

A study published in Nature Communications in May suggested that there is an “absolute limit” to the human lifespan of about 120-150 years.

Using mathematical modeling, researchers from Singapore-based company Gero found that at this limit “the human body completely loses its ability to recover from stresses such as illness and trauma”, leading to death. Direct Science.

That means even if you’ve managed to avoid serious life threats, such as heart disease or being hit by a car – your body will eventually reach the point where it can’t be helped. recovers even from everyday stressors.

But that’s not all bad news. If we could find a way to increase “resilience” in old age, the researchers argue, not only could our lifespans be increased, but more importantly, our healthy lifespans could also be improved. can be extended.

Study co-author Peter Fedichev said: “Measuring something is the first step before introducing an intervention. American Science. The next step now is to find a way to “prevent the loss of resilience”.

But do we want to live forever?

In one Pew Research Center In the 2013 survey of radical life extension in the US, 56% of adults said they would not want to live for a minimum of 120 years, which is considered the upper limit of human lifespan.

Likewise, about two-thirds of adults in a 2016 health-promoting poll said they would not want a brain chip implant to improve their cognitive abilities (66). %) or synthetic blood to enhance their physical abilities (63%).

“What you see when you really look at the end of life, is a sense of a good life and a moment for that life to transform itself,” says Wolpe. “Young people have a harder time with that, but older people don’t.”
