Might future humans resurrect the dead?

Death is brutal. It extinguishes consciousness. It terminates relationships, dissolves aspirations, and forecloses opportunities. It shatters any chances of us nurturing new skills, visiting new locations, exploring new art, feeling new emotions, keeping up with the developments of friends and family, or actively sharing our personal wisdom.

Or does it? Is death really the end?

Traditionally, such a question has seemed to belong to the field of religion, or, perhaps, to psychical research. However, nowadays, an answer to this existential question is emerging from a different direction. In short, this line of thinking extrapolates from past human progress to suggest what future human progress might accomplish. Much more than we have previously imagined, is the suggestion. We humans may become like Gods, not only with the power to create new life, but also with the power to resurrect the dead.

As centuries have passed, we humans have acquired greater power and capability. We have learned how to handle an increasing number of diseases, and how to repair bodies damaged by accident or injury. As such, average lifespans have been extended. For many people, death has been delayed – as we live on average at least twice as long as our ancestors of just a few centuries back.

Consider what may happen in the decades and centuries to come, as humans acquire even greater power and capability.

Writers Ben Goertzel and Giulio Prisco summarise possible answers, in their visionary 2009 article “Ten Cosmist Convictions”:

Humans will merge with technology, to a rapidly increasing extent. This is a new phase of the evolution of our species, just picking up speed about now. The divide between natural and artificial will blur, then disappear. Some of us will continue to be humans, but with a radically expanded and always growing range of available options, and radically increased diversity and complexity. Others will grow into new forms of intelligence far beyond the human domain…

We will spread to the stars and roam the universe. We will meet and merge with other species out there. We may roam to other dimensions of existence as well, beyond the ones of which we’re currently aware…

We will develop spacetime engineering and scientific “future magic” much beyond our current understanding and imagination.

Spacetime engineering and future magic will permit achieving, by scientific means, most of the promises of religions — and many amazing things that no human religion ever dreamed. Eventually we will be able to resurrect the dead by “copying them to the future”…

There’s much more to the philosophy of cosmism than I can cover in a single blogpost. For now, I want to highlight the remarkable possibility that beings, some time in the future, will somehow be able to reach back through time and extract a copy of human consciousness from the point of death, in order for the deceased to be recreated in a new body in a new world, allowing the continuation of life and consciousness. Families and friends will be reunited, ready to enjoy vast new vistas of experience.

Giulio develops these themes in considerable depth in his book Tales of the Turing Church, of which a second (expanded) edition has just been published.

The opening paragraphs of Giulio’s book set the stage:

This isn’t your grandfather’s religion.

Future science and technology will permit playing with the building blocks of space, time, matter, energy, and life, in ways that we could only call magic and supernatural today.

Someday in the future, you and your loved ones will be resurrected by very advanced science and technology.

Inconceivably advanced intelligences are out there among the stars. Even more God-like beings operate in the fabric of reality underneath spacetime, or beyond spacetime, and control the universe. Future science will allow us to find them, and become like them.

Our descendants in the far future will join the community of God-like beings among the stars and beyond, and use transcendent “divine” technology to resurrect the dead and remake the universe.

Science? Spacetime? Aliens? Future technology? I warned you, this isn’t your grandmother’s religion.

Or isn’t it?

Simplify what I said and reword it as: God exists, controls reality, will resurrect the dead and remake the universe. Sounds familiar? I bet it does. So perhaps this is the religion of our grandparents, in different words…

Giulio’s background is in physics: he was a senior manager in European science and technology centres, including the European Space Agency. I’ve know him since 2006, when we met at the TransVision conference in Helsinki in August that year. He has spoken at a number of London Futurists events over the years, and I’ve always found him to be deeply thoughtful. Since his new book breaks a lot of new ground, I took the opportunity to feature Giulio as the guest on a recent London Futurists video interview:

The video of our discussion lasts 51 minutes, but as you’ll see, the conversation could easily have lasted much longer: we stepped back several times from topics that would have raised many new questions.

Evidently, the content of the video isn’t to everyone’s liking. One reviewer expressed his exasperation as follows:

Absurd. I quit at 8:15

At first sight, it may indeed seem absurd that information from long-past events could somehow be re-assembled by beings in the far-distant future. The information will have spread out and degraded due to numerous interactions with the environment. However, in his book, Giulio considers various other possible mechanisms. Here are three of them:

  • Modern physics has the idea that spacetime can be curved or deformed. Future humans might be able to engineer connections between past spacetime locations (for example, someone’s brain at the point of death) and a spacetime location in their own present. This could be similar to what some science fiction explores as “wormholes” that transcend ordinary spacetime connectivity
  • Perhaps indelible records of activity could be stored in aspects of the multi-dimensional space that modern physics also talks about – records that could, again, be accessed by hugely powerful future descendants of present-day humans
  • Perhaps the universe that we perceive and inhabit actually exists as some kind of simulation inside a larger metaverse, with the controllers of the overall simulation being able to copy aspects of information and consciousness from inside the simulation into what we would then perceive as a new world.

Are these possibilities “absurd” too? Giulio argues that we can, and should, keep an open mind.

You can hear some of Giulio’s arguments in the video embedded above. You can explore them at much greater length in his book. It’s a big book, with a comprehensive set of references. Giulio makes lots of interesting points about:

  • Different ideas about physics – including quantum mechanics, the quantum vacuum, and the ultimate fate of the physical universe
  • The ideas featured by a range of different science fiction writers
  • The views of controversial thinkers such as Fred Hoyle, Amit Goswami, and Frank Tipler
  • The simulation argument, developed by Hans Moravec and popularised by Nick Bostrom
  • The history of cosmism, as it developed in Russia and then moved onto the world stage
  • Potential overlaps between Giulio’s conception of cosmism and ideas from diverse traditional religious traditions
  • The difference between the “cosmological” and “geographical” aspects of religions
  • The special significance of free-will, faith, and hope.

Despite covering weighty topics, Giulio’s writing has a light, human touch. But to be clear, this isn’t a book that you can rush through. The ideas will take time to percolate in your mind.

Having let Giulio’s ideas percolate in my own mind for a couple of weeks, here are my reflections.

The idea of future “technological resurrection” is by no means absurd. The probability of it happening is greater than zero. But for it to happen, a number of things must be true:

  1. The physical laws of the universe must support at least one of the range of mechanisms under discussion, for the copying of information
  2. Beings with sufficient capability will eventually come into existence – perhaps as descendants of present-day humans, perhaps as super-powerful aliens from other planets, or perhaps as intelligences operating at a different level of spacetime reality
  3. These beings must care sufficiently about our existence that they wish to resurrect us
  4. The new beings created in this process, containing our memories, will be us, rather than merely copies of us (in other words, this presupposes one type of answer to the question of “what is consciousness”).

Subjectively, this compound probability feels to me like being significantly less than 10%. But I accept that it’s hard to put numbers into this.

Someone else who offers probabilities for different routes to avoiding death is the Russian researcher Alexey Turchin. Alexey gave a fascinating talk at London Futurists back in April 2016 on the subject “Constructing a roadmap to immortality”. The talk was recorded on video (although the audio is far from perfect, sorry):

Alexey describes four plans, with (he says) decreasing probability:

  • “Plan A” – “survive until creation of strong and friendly AI” (which will then be able to keep everyone alive at that time, alive for as long as each person wishes)
  • “Plan B” – “cryonics” – “success chances as 1 – 10 per cent”
  • “Plan C” – “digital immortality” – “recording data about me for my future reconstruction by strong AI” – “even smaller chances of success”
  • “Plan D” – “immortality some how already exists” without needing any special actions by us – but this “is the least probable way to immortality”.

If you’d like to read more analysis from Alexey, see his 39 page essay from 2018, “Classification of Approaches to Technological Resurrection”.

I’m currently preparing a new talk of my own, that aims to draw wider attention to the ideas of thinkers such as Giulio and Alexey.

The talk is being hosted by DSMNTL and is scheduled for the 15th of April. The talk is entitled “Disrupting death: Technology and the future of dying”. Here’s an extract from the description:

Death stalks us all throughout life. We’re painfully aware that our time on earth is short, but the 2020s bring potential new answers to the problem of death.

Thanks to remarkable technologies that are being conceived and created, now may be the time to tackle death as never before. Beyond the old question of whether God created humanity in His image or humanity created gods in our image, it’s time to ask what will happen to humanity once technology gives us the power of Gods over life, death, and resurrection. And what should we be doing, here and now, in anticipation of that profound future transition?

This DSMNTL talk shares a radical futurist perspective on eight ways people are trying to put death in its place: acceptance, traditional faith in resurrection, psychic connectivity, rejuvenation biotechnology, becoming a cyborg, cryonic preservation, digital afterlife, and technological resurrection. You’ll hear how the relationship between science and religion could be about to enter a dramatic new phase. But beware: you might even make a life-changing death-defying decision once you hear what’s on offer.

I’ll give the last word, for now, to Giulio. Actually it’s a phrase from Shakespeare’s play Hamlet that Giulio quotes several times in his book:

There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy.

Technological Resurrection: An idea ripe for discussion

Like it or not, humans are becoming as gods. Where will this trend lead?

How about the ability to bring back to life people who died centuries ago, and whose bodies have long since disintegrated?

That’s the concept of “Technological Resurrection” which is covered in the recent book of the same name by Dallas, Texas based researcher Jonathan A. Jones.

The book carries the subtitle “A thought experiment”. It’s a book that can, indeed, lead readers to experiment with new kinds of thoughts. If you are ready to leave your normal comfort zone behind, you may find a flurry of unexpected ideas emerging in your mind as you dip into its pages. You’re likely also to encounter considerable emotional turmoil en route.

The context

Here’s the context. Technology is putting within human reach more and more of the capabilities that were thought, in former times, to be the preserve of divine beings:

  • We’re not omniscient, but Google has taken us a long way in that direction
  • We’re not yet able to create life at will, but our skills with genomic engineering are proceeding apace
  • Evolution need no longer proceed blindly, via Darwinian Russian roulette, but can benefit from conscious intelligent design (by humans, for humans)
  • Our ability to remake nature is being extended by our ability to remake human nature.
  • We can enable the blind to see, the deaf to hear, and the lame to walk
  • Thanks to medical breakthroughs, we can even bring the dead back to life – that is, the cessation of heart and breath need no longer herald an early grave.

But that’s just the start. It’s plausible that, sooner or later, humanity will create artificial superintelligence with powers that are orders of magnitude greater than anything we currently possess. These enhanced powers would bring humanity even closer to the domain of the gods of bygone legends. These powers might even enable technological resurrection.

Some details

In more detail: Profound new engineering capabilities might become available that can bridge remote sections of space and time – perhaps utilising the entanglement features of quantum physics, perhaps creating and exploiting relativistic “wormholes”, or perhaps involving unimagined novel scientific principles. These bridges might allow selected “copying” of consciousness from just before the moment of death, into refined bodies constructed in the far future ready to receive such consciousness. As Jonathan Jones explores, this copying might take place in ways that circumvent the time travel paradoxes that often feature in science fiction.

That’s a lot of “mights” and “maybes”. However, when contemplating the range of ideas for what might happen to consciousness after physical death, it would be wise to include this option. Beyond our deathbed, we might awaken to find ourselves in a state akin to paradise – surrounded by resurrected family and friends. Born 1945, died 2020, resurrected 2085? Born 1895, died 1917, resurrected 2087?

The book contains a number of speculative short stories to whet readers’ appetites to continue this exploration. These stories add colour to what is already a colourful, imaginative book. The artistic license is grounded in a number of solid references to science, philosophy, psychology, and history. For example, there’s a particularly good section on Russian “cosmist” thinkers. There’s a review of how films and novels have dealt with similar ideas over the decades. And the book is brought up to date with a discussion of contemporary transhumanists, including Ray Kurzweil, Ben Goertzel, Jose Cordeiro, and Giulio Prisco.

Futurists like to ask three questions about forthcoming scenarios. Are they credible (as opposed to being mere flights of fantasy). Are they actionable, in that individual human actions could alter their probability of occurring. And are they desirable.

All three questions get an airing in the pages of the book Jonathan Jones has written. To keep matters short, for now I’ll focus on the third question.

The third question

The idea of technological resurrection could provide much-needed solace, for people whose lives otherwise seem wretched. Perhaps death will cease to be viewed as a one-way ticket to eternal oblivion. What’s more, the world might benefit mightily from a new common quest to advance human capability, safely, beyond the existential perils of modern social angst, towards being able to make technological resurrection a reality. That’s a shared purpose which would help humanity transcend our present-day pettiness. It’s a route to make humanity truly great.

However, from other points of view, the idea of technological resurrection could be viewed as an unhelpful distraction. Similar to how religion was criticised by Karl Marx as being “the opium of the people” – an illusory “pie in the sky when you die” – the vague prospect of technological resurrection could dissuade people from taking important steps to secure or improve long-term health prospects. It might prevent them from:

  • Investigating and arranging cryonics support standby services
  • Channelling funds and resources to those researchers who may be on the point of abolishing aging
  • Encouraging the adoption of health-promoting lifestyles, economic policies, and beneficial diets and supplements
  • Accelerating the roll-out of technoprogressive measures that will raise people around the world out of relative poverty and into relative prosperity.

Finally, the idea of technological resurrection may also fill some minds with dread and foreboding – if they realise that devious, horrible actions from their past, which they believed were secret, might become more widely known by a future superintelligence. If that superintelligence has the inclination to inflict a punitive (hellish) resurrection, well, things gain a different complexion.

There’s a great deal more that deserves to be said about technological resurrection. I’m already thinking of organising some public meetings on this topic. In the meantime, I urge readers to explore the book Jonathan Jones has written. That book serves up its big ideas in ways that are playful, entertaining, and provocative. But the ideas conveyed by the light-hearted text may live in your mind long after you have closed the book.

PS I’ve addressed some of these questions from a different perspective in Chapter 12, “Radical alternatives”, of my own 2016 book “The Abolition of Aging”.
