New Transhumanist theory thinks Dyson Spheres could unlock human immortality

WHY THIS MATTERS IN BRIEF

Ironically there are many paths to immortality, but this one is the most far out there yet …

Step back twenty years ago and when you were dead you were dead. Today though, well, it’s not quite that black and white – especially as we have the technology nowadays to bring you back as an avatar, a bot, a digital human or virtual being, and even, at a highly unethical push, even your physical self, complete with downloaded memories. Sort of. Now, theorists are taking some of these ideas and going one giant weird step further, and frankly, I thought it might be fun to share so go nuts…

Imagine this: In the far, far future, long after you’ve died, you’ll eventually come back to life. So will everyone else who ever had a hand in the history of human civilization. But in this scenario, returning from the dead is the relatively normal part. To paraphrase, the journey home will be a hell of a lot weirder than the destination.

Here’s how it will apparently go down: A megastructure called a Dyson Sphere will provide an Artificial Super Intelligence (ASI) with the enormous amounts of power it needs to collect as much historical and personal data about you, so it can rebuild your exact digital copy. Once it’s finished, you’ll live your whole life, again, in a simulated reality, and when the time comes for you to die, again, and  you’ll be transported into a simulated afterlife, à la Black Mirror’s “San Junipero,” where you’ll get to hang out with your friends, family, and favourite celebrities forever.

Yes, this is mind-boggling. But someday, it might also be very real. Or so the team think. And, based on the trajectory of today’s technology, the development of digital humans and virtual beings, and the Metaverse, there’s actually no reason why it couldn’t one day come to pass. Yep, the future’s weird. Welcome to weird.

This is Plan C of the “Immortality Roadmap,” a project on which Russian transhumanist and life extensionist Alexey Turchin has been working since 2014. Turchin recently laid out the details in a paper he published with fellow transhumanist Maxim Chernyakov called “Classification of Approaches to Technological Resurrection.”

Plans A, B, and D involve life extension, cryogenics, and quantum immortality, respectively. You can find arguments justifying how each can lead to immortality in the paper.

When Turchin was 11 years old, a girl in his class died. The experience planted the first seeds of the possibility of eternal life in his young mind.

“I started to think in science-fiction terms about what could be done,” said Turchin.

In 2007, he became a member of the Russian Transhumanist Movement, a community that works to prepare Russians to embrace the technologies that will help them transcend their current physical and mental limitations. Turchin cofounded Russia’s first transhumanist political party in 2012, and for the last few years, he’s been perfecting his Immortality Roadmap and proactively recording every tidbit of his life.

Turchin is recording and keeping diaries of every dream, conversation, and daily experience he has. This practice of “ubiquitous surveillance,” throughout which Turchin says he even records his own biases, is necessary because the superintelligent AI needs to subject future resurrectees to the exact same developmental conditions they went through when they lived for the sake of their “authenticity,” he says.

Once the AI creates your precise digital copy, anything is possible -even restoration to biological life, says Turchin. The AI will doggedly search for your DNA – it will even dig up your grave, er yuck – because only then will it be able to create a clone of your physical body, wherein your digital copy will find its temple.

Now take the singular example of digital immortality and multiply it to the scale of the billions of people who have ever lived, accounting for many copies of the same simulation with different variants of how things could develop, which will exponentially grow with any choice they make at the same time. There’s no way Earth’s power output could provide us with the computational resources for this endeavour. We need the sun. Better yet, we need a Dyson Sphere around the sun.

The late physicist Freeman Dyson proposed his megastructure concept in a 1960 Science paper, “Search for Artificial Stellar Sources of Infrared Radiation.” The gist: It’s a hypothetical shell encircling the sun to harness a large part of the majestic 400 septillion watts per second of energy our star emits on any given day. That’s on the order of a trillion times our current worldwide energy usage.

Think of a Dyson Sphere as many separate satellites with separate orbits, as one enormous structure would be gravitationally unstable, says Turchin. He envisions the megastructure as a fleet of black or slightly orange solar farms, bonded together into a staggering 300 million-kilometer shell around the sun. It will be the ultimate alien megastructure, one that will signal the passage of our species from a planetary species to an interstellar one.

There’s just one small problem: We can’t actually build such a thing. Yet. Although NASA have started 3D and 4D printing space structures in low Earth orbit.

“An actual sphere around the sun is completely impractical,” Stuart Armstrong, a research fellow at Oxford University’s Future of Humanity Institute who has studied megastructure concepts.

The tensile strength needed to prevent the Dyson Sphere from tearing itself apart vastly exceeds that of any known material, Armstrong said. Plus, the sphere wouldn’t gravitationally bind to its star in a stable fashion. If any part of the sphere were nudged closer to the star – say, by a meteor strike – then that part would be pulled preferentially toward the star, creating instability.

But that’s a minor point in the grand transhumanist scheme of things …
