Artificial intelligence (AI) has always aimed to go beyond specific tasks and delve into the realm of human-like thinking. The ultimate goal is to create artificial general intelligence (AGI), a system capable of adapting and creating with the same versatility as humans.
Modern language models have made significant progress in language mastery, surprising researchers with their problem-solving abilities. However, they still lack open-ended learning, making them struggl to expand their knowledge beyond the initially trained material. Ben Goertzel of SingularityNET describes this limitation as the “robot college student test” – they cannot progress beyond what they have been taught.
The one area where AGI models have excelled is language comprehension. They possess the ability to understand and respond to any given sentence, even if it’s informal or fragmented. However, they falter in other aspects of human thinking and understanding. Neuroscientist Nancy Kanwisher asserts that these models are primarily language processors and lack real-world perception and interaction.
Large language models mimic the brain’s language abilities and algorithms but do not possess the multifaceted functions of cognition, memory, navigation, or social judgments. Human intelligence is a complex system that combines various overlapping functions across the brain. The modular approach in AI systems attempts to replicate this diversity to enhance their capabilities.
OpenAI’s Generative Pre-trained Transformer (GPT) allows users to select plug-ins for specific functions such as math or internet search. These plug-ins utilize external knowledge banks related to their respective fields. Additionally, the core language system of GPT may consist of separate neural networks or “experts” working collaboratively to answer queries. This form of modularity improves computational efficiency, as training and running smaller networks is more manageable than a single large one.
However, the trade-off for modularity is the challenge of understanding how different modules work together to create a coherent sense of self or consciousness. The integration of information and decision-making processes remains an open question. Global workspace theory (GWT) presents one hypothesis stating that consciousness acts as a common ground, enabling modules to exchange information and request assistance. AI researchers find GWT intriguing as it suggests a crucial link between consciousness and high-level intelligence.
Developers like Goertzel are incorporating workspace concepts into AI systems, not to create conscious machines, but to emulate the underlying principles of consciousness and achieve human-like intelligence. While the possibility of inadvertently creating a sentient being with emotions and motivations exists, it is considered unlikely by experts like Bernard Baars, the founder of GWT. Nonetheless, the development of AGI could provide valuable insights into the nature and mechanics of intelligence itself.
Throughout the history of AI research, neuroscience and AI have mutually influenced and inspired each other. The roots of GWT can be traced back to early AI concepts proposed by Oliver Selfridge and Allen Newell, who envisioned computer systems as either a chaotic collection of demons or a group of mathematicians solving problems. Using AI as a theoretical platform, Baars formulated GWT in the 1980s as a model of human consciousness.
While the quest for AGI continues, language models have illuminated the boundaries of AI capabilities. They excel in language processing but still lack the holistic understanding and contextual awareness that characterize human intelligence. As researchers continue to explore the potential of AI, astonishing discoveries await, shedding light on the intricacies of our own minds and paving the way for a new era of artificial intelligence.
FAQs
1. What is artificial general intelligence (AGI)?
Artificial general intelligence refers to a system that exhibits human-like adaptability and creativity, surpassing the capabilities of narrow AI systems designed for specific tasks.
2. How do language models perform in terms of AGI?
Language models have shown impressive language comprehension skills but lack other essential cognitive abilities. While they excel at parsing and responding to text, they struggle with tasks outside the realm of language processing.
3. Can language models acquire open-ended learning?
Current language models still face limitations when it comes to open-ended learning. Once trained on specific materials, their knowledge remains fixed, preventing further expansion.
4. How do modularity and workspace theories enhance AI systems?
Modularity allows AI systems to mimic the distributed functions of the human brain, enabling specialized task processing. Workspace theories, such as the Global Workspace Theory (GWT), propose that consciousness acts as a platform for information exchange, contributing to higher-level intelligence in AI systems.
5. Could AI systems unintentionally develop consciousness?
While the possibility exists, experts believe that the accidental creation of conscious AI systems is improbable. The focus of AGI development lies in achieving human-like intelligence rather than emulating conscious beings.
The artificial intelligence (AI) industry is experiencing significant advancements, particularly in the development of language models. The ultimate goal is to create artificial general intelligence (AGI), which is a system that possesses human-like adaptability and creativity. While language models have made remarkable progress in language comprehension and problem-solving, they still face limitations in open-ended learning.
