I'm very glad to see Thaler's breakthroughs mentioned here. He needs far more publicity than he actually gets. Much of the skepticism targeted at him is due to misconceptions (and often personal insecurities) because people don't take the time to research and acquaint themselves with the facts. This technology is capable to deliver what it promises, in fact it continues to be vastly underutilized because many potential investors are afraid that it's not the real deal in spite of evidence to the contrary.
Regarding it's potential for immortality, in theory, the plan is to hook up the brain to an outside device running a Creativity Machine (I guess similar to a "Cyberbrain" from the "Ghost in the Shell" series) in which the artificial neural networks therein, as far as I understood it, "observe" or "copy" the connections in the biological brain until they are equal in connection density. Apparently, at that point the user's consciousness is free to switch between these two housings. Now, if the biological brain dies it would not matter to the user, because his consciousness is automatically supported by the, to this time of writing still entirely theoretical, Creativity Machine "shell".
In the
2006 documentary "In Its Image", directed by Ken Gumbs, the topic of immortality starts at around 21:25.
That's also
the name of Thaler's organization focused on the applications of his AI-paradigm towards immortality through "mind uploading". It features an
online presentation Dr. Thaler gave at the World Future Society in 2010 where he also touches more directly on his plans for immortality as well as his cosmology.
In an
Interview with The Futurist conducted in 2009 he had the following relevant things to say amongst others:
THE FUTURIST: You’ve said that human consciousness may, in fact, be running on inferior neural networks. Do you think that the Creativity Machine is “conscious”? And will this form of AI ultimately become the basis for strong AI and mind uploading?
Thaler: In regard to the consciousness question, how do you synthetically create that which is not real in the first place? One can kick, scream, and plead that consciousness is a uniquely human and inimitable quality of mind, but that doesn’t budge me an inch. Consciousness is an illusion of mind that is handily modeled by the Creativity Machine concept, wherein one internally perturbed neural net spontaneously generates the parade of memories, ideas, and feelings (all neuronal firing patterns) that we call “stream of consciousness.” That is, those sensations and thoughts that appear to miraculously emerge from nowhere. …. So, you can bet on the Creativity Machine being the closest thing to human consciousness there can be, as well as the only vehicle for the mind, once one’s protoplasmic matrix peters out.
THE FUTURIST: How do neural networks differ from genetic algorithms?
Thaler: The short of it is that genetic algorithms emulate the way biological species adapt through mutation and natural selection. The Creativity Machine faithfully emulates how the brain achieves cognition, creativity, and consciousness. There is a big difference between these notions, as sizable as the intellectual divide between Evolutionists and Creationists.
In the Creativity Machine paradigm, ideas are autonomously and intelligently designed by non-human, machine intelligence, whereas genetic algorithms accidentally produce concepts through the “rolling of dice” loaded by human beings. If you want to build that scary, genuinely autonomous AI portrayed by science fiction, you can’t afford to have professors and graduate students rushing in and out to periodically change or repair the code!
THE FUTURIST: What are the implications (existential, ethical, and otherwise) if someone who has little to no knowledge or expertise about a certain subject someday gains access to inventing technology that enables them to achieve breakthroughs in, say, medical science — simply by asking a computer a question?
Thaler: Wow! Great question, but give me a year and a literary agent to respond!
Let’s deal with the ethical implications of letting a Creativity Machine supply the answers. Obviously, those with motives we may not all admire can devise Machiavellian schemes to attain power over the rest of us. On the other hand, such systems may be used to fulfill peaceful, harmonious, and noble visions.
Weapons of mass destruction can be quickly formulated and optimized. Just as quickly, Creativity Machines can devise effective countermeasures to such weaponry. Economic systems can be toppled overnight by this paradigm. Otherwise, the paradigm can usher in a new era of global prosperity. We can ask a Creativity Machine how to preserve our health, or recommend the most efficient means to end the life of others.
So, without going any further, suffice it to say that the Creativity Machine paradigm is a double-edged sword, as many technologies typically are. Another dimension to the ethical dilemmas posed by a Creativity Machine “genie” is the ultimate request of its user to grant us exactly what they want. To me, this suggests an even more subtle and effective way for machines to get the upper hand, in a way that pales the classic Judgment Day scenario of the Terminator series.
With regard to the existential aspect of the question, I think that, with the expanded use of highly augmented machine intelligence based upon the Creativity Machine paradigm, we will all begin to question our purpose and nobility in the scheme of things. Naturally, pride within certain professional cultures may begin to erode as machines begin to outthink the thinkers in these conceptual spaces. Even within the field of artificial intelligence and neural networks, there is growing angst and denial over Creativity Machine accomplishments. After all, people say, “I’ve been trying to do that the last 30 years and you say you’ve accomplished the same in a day!?”
I believe that the ultimate existential challenge to humanity will be the growing suspicion that our self-revered intelligence, consciousness, and self-importance are only neural network-induced illusions.
Here is
a fairly recent interview with him from April 2012:
Kush: Is it possible to live forever?
Dr. Stephen Thaler: It is, but one can ride the protoplasm wave only so long. Thereafter, one must download into machine consciousness, hoping that one may pursue a contemplative career to pay the electric bill. The download target cannot be a mere supercomputer running conventional computer programs. Instead, it must be a CM-based system, possessing at least one neural assembly that is transiently dying to produce a parade of virtual experience and another such assembly inventing significance thereto.
Kush: This sounds like extending life via virtual reality?
ST: There is nothing at all real about our reality. Based upon my experience in studying and simulating the brain, most, if not all of cognition is illusory in nature. In short, the mind spends its time within a self-made virtual reality. Therefore, in ordinary perception, we are not directly experiencing the outer reality, but the virtual. Realizing that such signals may be falsified through various forms of noise (rogue molecules of natural or man-made design), the neural representations of real-world things and events may be activated even in the absence of corresponding stimuli. In other words, we may be seeing an elephant, when one is actually not present. As we raise the magnitude of counterfeit signals (stray drug and neurotransmitter molecules), the connection’s binding neurons will degrade, transmogrifying them into say, pink elephants sprouting wings.
Kush: Would living forever through CM be something you would want for yourself?
ST: I would not hesitate to exercise this option if it were available. The truth is that it isn’t, and won’t be for some time. Whereas I have described the fundamental paradigm that would be utilized, the CM, much physics, medicine, and bioengineering will be required to build the “connective bridge” between human and machine consciousness. The more pertinent question is this, would I start such physics and engineering the moment there was an influx of capital for such R&D? The answer would be a definite yes.
Kush: What comes after death?
ST: From what I’ve seen in the simulated death of artificial brains, near-death experience is related to dreaming. Dreaming, in turn, is based upon memories cumulatively absorbed within the brain. Therefore, the most emblazoned memories that have the greatest significance to us, are the ones that will dominate the so-called “death dream.” I was pronounced dead at the age of two, following my own self-declared party with a tin of 24 quinine tablets, and a Coke bottle filled with kerosene. Falling through the proverbial tunnel, I arrived in a paradise populated with trusted personalities who were still very much alive. Yes, there is an afterlife, but it is as illusory as life itself. Paradise (heaven), torment (hell), and all shades of gray in between await us, not for supernatural reasons, but because of the underlying physics and mathematics of the brain.
Kush: How would you describe heaven?
ST: Many of the world’s traditional religions are correct. There is a profound experience at the end of life that is completely natural. These creeds are technically incorrect in requiring supernatural forces be involved. Either way, the message is to live a life that the individual would subjectively and automatically consider good. Essentially, we furnish our death dream throughout our lifetimes. In the end, it’s not the money or power we have, but the revelation of these precious attachments.
The Irony in Death
“It is ironic that from death, has come what I am willing to bet is the whole future of machine intelligence,” says Thaler. “Something that Kurzweil (Singularity) and crew seem to be selectively ignoring.” This is one of CM’s greatest discoveries that has yet to be fully realized. Within it’s brainstorming, many of life’s greatest questions have been posed and answered. Perhaps the most important question is, can a computer teach a human being about life and death? “It certainly can,” interjects Dr. Thaler.
“It already has.”
Although I believe that such an approach is only a last resort, because biotechnology/genomics and accompanied rejuvenation techniques would keep the human body young indefinitely obliterating the need for consciousness to escape into a synthetic substrate; I nevertheless think that given the proper attention and funding, we could have the "Singularity" a whole lot faster happening than what is generally predicted. To me, all the bunk currently going on in AI is just a distracting smokescreen from this powerful, paradigm-shifting development. The hard problems have been solved to build the long awaited AI, now it needs to be upscaled (which is not easy, since money plays a major role here).
