Woody Allen’s famous quote on immortality “I don’t want to achieve immortality through my work; I want to achieve immortality through not dying. I don’t want to live on in the hearts of my countrymen; I want to live on in my apartment.” has a different meaning for Dmitry Itskov. He aims to achieve immortality both through his work and through not dying.
Dmitry Itskov is a Russian entrepreneur and billionaire, best known for creating the 2045 initiative, which aims to achieve cybernetic immortality by the year 2045.
Cited in a recent BBC article, Dmitry Itskov promises that “Within the next 30 years, I am going to make sure that we can all live forever.”
The idea sounds preposterous, but there is no doubt he is not deranged and is serious about it. It is indeed a breathtaking ambition, to achieve mind uploading by the year 2045, but could it actually be done?
The scientific director of the 2045 initiative, Randal Koene, a neuroscientist, who has done work on diverse aspects of brain modeling, believes the task is extremely difficult but not impossible, at least in theory. In a number of videos and presentations available in YouTube, he explains how existing technologies could be used, in principle, to reach this goal.
The question remains: will it ever become possible and, if so, when?

Recent news about OpenWorm, a project that aims at recreating in a computer the behaviour of a complete animal, the roundworm Caenorhabditis elegans. The OpenWorm project aims at constructing a complete model of this worm, not only of the 302 neurons and the 95 muscle cells, but also of the remaining thousand cells in each worm (more exactly, 959 somatic cell plus about 2000 germ cells in the hermaphrodite sex and 1031 cells in the males).
The one millimeter long worm C. elegans has a long history in science, as one of the animals more extensively used as a model for the study of simple multicellular organisms. It was the first animal to have its genome sequenced, in 1998.
But well before that, in 1963, Sydney Brenner proposed it as a model organism for the investigation of neural development in animals. In an effort that lasted for more than twelve years, the complete structure of the brain of C. elegans was reverse engineered, leading to a diagram of the wiring of each neuron in this simple brain. The effort of reverse engineering the worm brain included slicing, very thinly, several worm brains, obtaining roughly 8000 photos of the slices using an electron microscope and connecting, mostly by hand, each neuron section of each slice to the corresponding neuron section in the neighbor slices. The complete wiring diagram of the 302 neurons and the roughly 7000 synapses, which constitute the brain of this simple creature, was described in minute detail in a 340 pages article, published in 1986, entitled The Structure of the Nervous System of the Nematode Caenorhabditis elegans, with a running head The Mind of a Worm.
In 2008, IEEE Spectrum, the flagship publication of the Institute for Electrical and Electronic Engineers, the major professional association of this area, dedicated a full issue to the question of the singularity. This issue received an award for the best single oopic magazine issue of that year.
In this special report, which is as actual today as it was in 2008, a number of scientists, visionaries and engineers give their opinion on whether a singularity will or will not exist. The issue covers topics related with the singularity, such as robotics, consciousness and quantum phenomena and artificial intelligence. A must read for anyone interested in the topic, one of the best unbiased assessments of whether the singularity will or will exist.
An article in the NY Times, by Kenneth Miller, addresses the question of whether or not we will one day be able to upload a brain, that is, to simulate in a computer the complete behaviour of a human brain.
The author, a neuroscientist from Columbia University, addresses carefully the challenges involved in mind uploading and whole brain emulation.
The author’s (wild) guess is that it will take centuries to determine a connectome that is detailed enough to enable us to try brain uploading.
However, he also recognises that we may not need to reconstruct all the fine details of a brain, with its billions of neurons and trillions of synapses, whose structure varies in time and space. Still, a level of detail incommensurable with existing technology would be required to even have a shot of creating a model that would reproduce actual brain behaviour.
It seems the singularity may not be over the corner, after all…
