Is this the end of death as we know it?

And then, Dan reckons, if these intelligences are friendly, we’ll all be “uploaded” – our entire personalities will be copied into the vast memory banks of these AIs – and we’ll live forever.

All Set for the Big Upload

My friend Dan thinks he’s going to live forever. He’s not religious, or one of those who believes that extreme calorie restriction will let him live a thousand years (or perhaps just feel like he is). No, thinking it through logically Dan has decided that the technological singularity is likely to happen in his lifetime.

According to this theory, popularised by Vernor Vinge and Ray Kurzweil among others, within the next 25 years humanity will create a superhuman intelligence, one that is capable of creating intelligences greater than its own. Humanity will no longer control the pace of technological development, which will rapidly advance to the point that our entire environment is directed by artificial intelligences.

And then, Dan reckons, if these intelligences are friendly, we’ll all be “uploaded” – our entire personalities will be copied into the vast memory banks of these AIs – and we’ll live forever. More than that, we’ll be able to spend time with our friends, we’ll never experience pain or suffering again, all imaginable forms of entertainment will be available to us, along with some that can’t be imagined at all. We’ll be happy, stimulated, in pleasant company for all eternity.

Of course, this is a remarkably similar promise to the assurances various religions have been giving for the past few thousand years. The technological singularity has been called the Geek Rapture or Rapture of the Nerds, referring to the belief held by some Christians that they will be taken up bodily into heaven to be with Jesus before the Day of Judgment. I’m fascinated by the similarities with religion; perhaps it’s simply impossible for many people to comfortably accept that they really are going to die, that nothing will come afterwards, that there’s no hope of rescue. If we can’t believe in God, could technology be the way, the truth and the life?

I’m reminded of the Doctor Who spin-off Torchwood, which is very robust in its constant assertion that there is nothing after death. In the very first episode, the team of alien-hunters uses a “resurrection glove” to momentarily bring a murdered man back to life. Asked what he saw after death, what there was to be seen, the murder victim replies, “Nothing. I saw nothing. Oh my god, there’s nothing.” And yet this statement was retrieved using this imaginary technology, the resurrection glove. One of the characters in Torchwood is immortal, others die and are returned to life using various pieces of alien gadgetry. Even for those who believe that they don’t believe in life after death, it seems impossible to stop imagining technological solutions to the problem.

Perhaps this is because of the vast array of problems technology can solve. We can speak to people on the other side of the world, fly through the air, carry the music of hundreds of orchestras with us in our pockets; why wouldn’t technology one day enable us to live forever? Or perhaps it’s simply a quirk of our brains; Scientific American magazine and artist Damien Hirst agree that the mind of a living being cannot conceive its own demise. Either way, I’ve agreed to try to get Dan into Jewish heaven if he puts in a good word for me with the Technological Singularity. That way we’re both covered.

  1. A team of Japanese scientists have created a device that enables the processing and imaging of thoughts and dreams as experienced in the brain to appear on a computer screen. While researchers have so far only created technology that can reproduce simple images from the brain, the discovery paves the way for the ability to unlock people's dreams and other brain processes. A spokesman at ATR Computational Neuroscience Laboratories said: "It was the first time in the world that it was possible to visualise what people see directly from the brain activity. "By applying this technology, it may become possible to record and replay subjective images that people perceive like dreams." The scientists, lead by chief researcher Yukiyaso Kamitani, focused on the image recognition procedures in the retina of the human eye. It is while looking at an object that the eye's retina is able to recognise an image, which is subsequently converted into electrical signals sent into the brain's visual cortex. The research investigated how electrical signals are captured and reconstructed into images, according to the study, which will be published in the US journal Neuron. As part of the experiment, researchers showed testers the six letters of the word "neuron", before using the technology to measure their brain activity and subsequently reconstruct the letters on a computer screen. Since Sigmund Freud published The Interpretations of Dreams over a century ago, the workings of the sleeping human mind have been the source of extensive analysis by scientists keen to unlock its mysteries. Dreams were the focus of a scientific survey conducted by the Telegraph last year in which it was concluded that dreams were more likely to be shaped by events of the past week than childhood traumas. ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Scientists Extract Images Directly From The Brain Researchers from Japan’s ATR Computational Neuroscience Laboratories have developed new brain analysis technology that can reconstruct the images inside a person’s mind and display them on a computer monitor, it was announced on December 11. According to the researchers, further development of the technology may soon make it possible to view other people’s dreams while they sleep. The scientists were able to reconstruct various images viewed by a person by analyzing changes in their cerebral blood flow. Using a functional magnetic resonance imaging (fMRI) machine, the researchers first mapped the blood flow changes that occurred in the cerebral visual cortex as subjects viewed various images held in front of their eyes. Subjects were shown 400 random 10 x 10 pixel black-and-white images for a period of 12 seconds each. While the fMRI machine monitored the changes in brain activity, a computer crunched the data and learned to associate the various changes in brain activity with the different image designs. Then, when the test subjects were shown a completely new set of images, such as the letters N-E-U-R-O-N, the system was able to reconstruct and display what the test subjects were viewing based solely on their brain activity. For now, the system is only able to reproduce simple black-and-white images. But Dr. Kang Cheng, a researcher from the RIKEN Brain Science Institute, suggests that improving the measurement accuracy will make it possible to reproduce images in color. “These results are a breakthrough in terms of understanding brain activity,” says Dr. Cheng. “In as little as 10 years, advances in this field of research may make it possible to read a person’s thoughts with some degree of accuracy.” The researchers suggest a future version of this technology could be applied in the fields of art and design — particularly if it becomes possible to quickly and accurately access images existing inside an artist’s head. The technology might also lead to new treatments for conditions such as psychiatric disorders involving hallucinations, by providing doctors a direct window into the mind of the patient. ATR chief researcher Yukiyasu Kamitani says, “This technology can also be applied to senses other than vision. In the future, it may also become possible to read feelings and complicated emotional states.” via N8
  2. It just so happens that Leary makes a number of posthumous appearances in Kurzweil’s The Singularity is Near, one of which is a fictional conversation with a character called Molly2004, who tries to figure out what will separate future humans from “bacteria who would talk and think” once we will be “saturating the universe with our intelligence.” Someone by the name of George2048 responds, “Indeed, Molly, that is fundamentally what the Singularity is all about. The Singularity is the sweetest music, the deepest art, the most beautiful mathematics…” “I’m still trying to envision what the universe will be doing,” Molly insists, whereupon Timothy Leary elucidates that “the universe will be flying like a bird…” via Rene | Space Collective
