: a world where AI is not just a “chatbot” you interact with, but an entity that is responsible for decision-making, scientific research, and even guiding humanity forward. Picture this Welcome to the world of , Artificial General Intelligence, which refers to AI systems as smart as humans, or greater. The quest for AGI has been a long-standing goal of the AI community, and recent advances in generative models have led to an increasing interest in their potential for achieving AGI. AGIs Generative Models A generative model is a type of machine learning model that is able to generate data samples, based on the large volumes of data that it is trained on (mostly text but now images as well). They can learn the patterns and structures of language from a large corpus of text and then generate new text that is coherent and follows the same patterns. The breakthrough here was to use “ ” – a type of neural network introduced in 2017. Transformers Now, more interestingly ……I asked GPT whether a Generative Model could generate something that was in its training data ( important as we move to AGIs ). never Here was its response: The answer is that, by identifying patterns and data structure, it may be able to, but will struggle to generate anything vastly different from the training data, and nothing “ ”. This is where we are currently. completely novel A mirror into your civilization...... If I had to describe GPT in an exciting way : Currently, Generative Models are a mirror of your civilization at a point in time, an automated and efficient record and reflection of everything you have done (once trained on everything). Given that humans have to generate science, art, and culture over many years, and then train the models on the entirety of this, there is a huge dependency – for these Generative models to have any value, the content on which the model is trained needs to be created first. These models may seem “smarter” than a human, but that is because they can access information generated by human culture and civilization instantly, whereas the humans, whose creativity came up with everything in the first place, cannot..... The Two Planets example To further illustrate, I have come up with the “two planets” example. In this scenario, imagine a duplicate civilization that has evolved to the same level as the Earth-Human civilization, say on Proxima Centauri. They would potentially have similar cultural achievements, and the same level of technology, although their language, appearance, etc could be different. At the same time as Earth, they develop Generative models and their version of GPT4. If we queried the Earth GPT4 model about anything on Proxima Centauri,
it would know nothing..... Of course, the reciprocal would apply as well. Even a more advanced model, a GPT 5 or 6, would have the same limitations, as it was not trained on any data from that planet. Would you still consider it “intelligence”? How useful would GPT be in this scenario? Well, if the aliens came here, they use the Earth GPT4 to learn all about our planet, culture, and achievements, assuming they quickly learned one of our languages that the GPT model is also familiar with. However, what was once being spoken of as an “AGI” may not be considered as such in this example. could What would be truly impressive is if the Earth could understand images or pass an IQ test from the hypothetical Proxima Centauri civilization…. GPT4 Innate Intelligence It is still amazing to me that GPT4 has an understanding of patterns, relationships in images, and the ability to pass a simple IQ test. Yes, it was trained by its creators to do this, based on data from mankind’s history, but once trained it has this ability. This brings us to the definition of Intelligence itself, and the concept of innate intelligence. “Every living being has some level of innate intelligence” While factors such as education, socioeconomic status, and cultural experiences can impact cognitive development and, in turn, influence IQ test performance in humans, these are not the only factors that influence intelligence. Genetics, neurological factors, and individual differences in learning capability also play a role. Therefore, there is an innate intelligence in every living being that plays a large part in the resulting visible intelligence demonstrated in the real world. How do we create artificial intelligence with some level of innate intelligence? Remember, if a human baby grows up in a culture different from his/her parents, learning a different language, the child still manages to learn quickly. Consider this – if we go back to the Two Planets example, and we are confident that while the Earth GPT4, 5, or 6 will have no knowledge of culture, language, events, etc from another civilization, it WILL manage to : Perform mathematical calculations that are constant in the universe Understand basic patterns that are constant in the universe Learn the basic structures of language that may be common in the universe Thus, ….have the ability to potentially learn from ANOTHER civilization and their data We then approach something very exciting…… we could then argue that in creating these models which, admittedly had to be trained on all our data to with, we are taking the first steps into creating something with a small amount of innate intelligence. And each subsequent model would then build on the previous in terms of capability, until….well, would iteration 7 or 8 be an AGI? start Are they AGIs? At this point, we need to be clear on what our definition of an AGI is, as we are finally moving in closer to creating one. I believe that our definition has become muddied. Does an AGI and the Singularity simply refer to any intelligence smarter than humans? If we go back to the 1993 definition of 'The Singularity’, as per the book “The Coming Technological Singularity” by , he spoke of “computers with super-human intelligence”. I could argue that GPT4 is already smarter than any human in terms of recalling knowledge, although it would be less capable of creativity, understanding, and emotional intelligence. Vernor Vinge He also talks about human civilization evolving to merge with this super intelligence. This hasn’t happened but brain interfaces have been built already. A brain interface into Chat GPT4 that would allow a human to call up all our civilization’s knowledge instantly, turning him/her into a “superhuman”, is actually possible with today’s technology. It could be argued then that we have met the criterion already for the singularity by the 1993 definition…… The Singularity If we move to futurist definition of the Singularity, he spoke of “…when technological progress will accelerate so rapidly that it will lead to profound changes in human civilization…”. Ray Kurzweil’s The year 2023, due to the emergence of GPT3 and then GPT4, is a watershed year in technological history, like the launch of the PC or the internet. Already there are conversations that I can only have with GPT4 that I cannot have with anyone else. The reason is that the humans around my may now be knowledgeable on particular topics, so I turn to GPT4. I sometimes do try to argue with it and present my opinion, and it responds with a counterargument. By our previous definition of what an AGI could be, it can be argued that we have already achieved it or are, at least, very close to it with GPT4. We are now certainly on the road to AGI, but we now have to clearly define a roadmap for it. This isn’t binary anymore, as in something is either an AGI or not. More importantly, the fear-mongering around AGIs will certainly not apply to all levels of AGI, once we clearly define these levels. This is particularly important, as recently people such as in the development of AGIs as they could be dangerous. While this is correct, this will also rob humanity of the great benefits that AI can bring to society. Elon Musk have publicly called for a “pause” Surely, if we create a roadmap for AGIs and identify which levels would be dangerous and which will not, we could then proceed with the early levels while exercising more caution at the more advanced levels. Right? The AGI Roadmap Below is a potential roadmap for AGIs with clearly defined stages. - Intelligent machines can perform specific tasks at the human level or better, such as playing chess or diagnosing diseases. They can quickly access the total corpus of humanity’s scientific and cultural achievements and answer questions. Are we here already? Level 1: Intelligent Machines - AGIs that can learn and adapt to new situations, improving their performance over time through experience and feedback. These would be similar to GPT4 but with continued learning post-training. Level 2: Adaptive Minds - AGIs capable of generating original and valuable ideas, whether in science, art, or business. These AGIs build on the scientific and cultural achievements of humans. They start giving us different perspectives on science and the universe. Level 3: Creative Geniuses - AGIs that can understand and respond to human emotions and needs, becoming trusted companions and helpers in daily life. This is the start of “emotion” in these intelligent models, however by this time they may be more than just models but start replicating the brain in electronic form. Level 4: Empathic Companions - AGIs that have subjective experiences, a sense of self, and the ability to reason about their own thoughts and feelings. This is where AGIs could get really unpredictable and potentially dangerous. Level 5: Conscious Thinkers - AGIs that vastly surpass human intelligence in every aspect, with capabilities that we cannot fully define yet with our limited knowledge. These AGIs are what I imagined years ago. These are AGIs that could improve on our civilization’s limitations, and derive the most efficient and advanced designs for just about anything, based on the base principles of physics ( ie. Operating at the highest level of knowledge in the universe). Level 6: Universal Minds As you can see, levels 1-3 may not pose much of a physical threat to humanity, while offering numerous benefits to society, therefore we could make an argument for continuing to develop this capability. Levels 4-6 could pose a significant threat to humanity. It is my view that any work on a level 4-6 AGI should be performed on a space station on Moonbase, to limit potential destruction on Earth. It is debatable whether the human civilization would be able to create a Level 6 AGI, even after 1000 years… Universal Minds Over the last few decades, I have been fascinated with the concept of an Advanced AGI, one that is more advanced than humans and that could thus rapidly expand our technological capability if we utilize it properly. Here is an old blog post on my Blog from 2007 where I was speculating on the Singularity being near, after following people like Kurzweil. What I always imagined was a “super intelligence” that understood the universe from base principles much better than we did, even if it was something we created. Imagine an intelligence that, once it gets to a certain point, facilitates its own growth exponentially. It would perform its own research and learning. It would be logical that such intelligence plays a role in the research  function of humanity going forward. It could take the knowledge given to it and develop scientific theory far more effectively than humans. Already today, for example, we see a lot of data used in Reinforcement Learning being simulated and generated by AI itself. And if the total data we have is limiting, we could then ask it to design better data collection tools for us, ie. Better telescopes, spacecraft, and quantum devices. A simple example that I would use would be the computing infrastructure that we use, on which everything else is built. Most computers today use what’s known as the “Von Neumann” architecture, which is shown below. The main drawback of this architecture is that data has to be constantly moved between CPU and memory, which causes latency. On top of this, we typically use the x86 CPU, then Operating systems like Windows or Linux, then applications are written in programming languages like C++. Imagine if we could engineer an optimal, efficient computing architecture, from base principles, with orders of magnitude improvements at the base architecture level, CPU level, OS level, and application software level. This would be a difficult task for humans to undertake today, not just in terms of the actual technical design, but also in building it, collaborating on the next layer above, and adopting the technology. With a “super-intelligent” Universal AI, it would have the power to generate every layer at once. It would also give us design schematics for the factories to build the new components, that too in the most quickest and efficient way. Now while all this seems like a convenient fantasy, I have used the above example to illustrate the great strides that a “ ” could help humanity make. Universal Mind Another example would be to ask it to calculate how best and efficiently to “ ” or “ ”. solve the world hunger problem solve the climate problem When you consider the above, it does seem like the benefits outweigh the problems, although the one problem that has always been brought up is that a Universal Mind may decide to destroy humanity. Hence I say, if we’re going to try to build it, take the necessary safeguards, over and above the Responsible AI safeguards that we have today, and consider building the AGI off-world, say on a space station or moon base, with the ability to cut networking and power if needed. Summary Hold on to your seats! ….. Some GPT models have already shown an impressive ability to pass IQ tests and learn basic mathematics, hinting at the potential for developing a level of intelligence that goes beyond simple text generation. Now that we have an example of a roadmap for AGIs ( above ), we can certainly see how GPT is the start of the early phases in this roadmap, although more technical breakthroughs will be needed to eventually get to the later stages. So buckle up and get ready – We don’t know where the end of this road is and where it will take us, but with GPT models now mainstream, we now know that as of 2023 we are at least on the road itself, traveling forward.
