Imagine a machine that doesn’t just answer questions but truly understands them. A machine that can connect ideas, solve new problems, and think through challenges like a human. This is the vision of Artificial General Intelligence (AGI), and it’s a goal that excites many. AGI promises an intelligence that is active, adaptable, and insightful—something much more than what we have today.

Microsoft AI CEO Mustafa Suleyman, believes that AI capable of improving itself and working independently could be here in the next 3–5 years. Sam Altman, CEO of OpenAI, shares a similar view, saying that the path to AGI is clear, and things are progressing faster than most people realize and that, it’s just an engineering problem to solve.

So, what exactly is missing from these AI models that prevents them from achieving true intelligence? Let’s dive in.

Pattern Matching vs. True Intelligence
LLMs have undoubtedly transformed how we interact with technology, enhancing our ability to process information and automate complex tasks. However, they do not think the way humans do. While these models are good at generating responses based on patterns they’ve detected in vast datasets, they lack a genuine understanding of the world or the concepts they discuss. Their operation is based on predicting the next sequence of words rather than reasoning through issues or grasping the meanings behind the language. This disconnect highlights the limitations of current AI in achieving true artificial general intelligence, where a deeper cognitive processing similar to human thought is necessary.

Recent research from Apple highlights this issue. When tested on math and logic problems, even the best AI models struggled. They didn’t actually reason through the problems—they just mimicked reasoning based on patterns they had seen before.

The Chinese Room Experiment: The Difference Between Mimicry and Understanding
The challenge of pattern recognition versus true understanding isn’t new. Philosopher John Searle’s 1980 Chinese Room experiment highlights this point. In the experiment, a person who doesn’t understand Chinese follows a set of rules to manipulate Chinese symbols and produce correct responses. To an outside observer, it might seem like the person understands Chinese, but in reality, they’re just following a set of instructions without any true comprehension.

This is a lot like how AI models work today. They generate human-like responses but don’t truly understand the meaning behind the words. They’re good at following patterns, but they’re not reasoning through problems the way we do.

True Intelligence: Understanding Beyond Patterns

True intelligence is more than just recognizing patterns and statistical correlations. It involves understanding basic principles, abstract ideas, and the ability to apply knowledge in new situations.

Humans don’t just react to things based on past data; we infer, deduce, and create new knowledge through reasoning and experience.
Key aspects of true intelligence include:

Consciousness and Self-Awareness: Being aware of oneself and the ability to reflect on one’s thoughts and actions.
Understanding and Context: Grasping the meaning behind information, not just the information itself.
Abstract Reasoning: The ability to think about objects, principles, and ideas that are not physically present.
Adaptability and Learning: Learning from new experiences and adjusting to new environments.
Emotional Intelligence: Recognizing and managing one’s emotions and the emotions of others, helping with social interactions.

These qualities enable humans to navigate complex situations, solve unexpected problems, and innovate—capabilities that pattern-based AI currently lacks.

Recognizing what true intelligence involves helps us understand the intricacies of the human brain that make such intelligence possible.

The Intricacies of the Human Brain

The human brain is a highly complex and efficient organ. It has about 86 billion neurons, each forming thousands of connections with other neurons, resulting in a network of immense computational power.

Features that distinguish the human brain include:

Parallel Processing: The brain processes vast amounts of information at the same time, integrating sensory inputs, memories, and emotions in real-time.
Neuroplasticity: The ability to form new neural connections enables learning and memory formation, allowing the brain to adapt continually.
Hierarchical and Modular Structure: Different brain regions specialize in various functions but work together, enabling complex tasks like language, abstract thought, and movement coordination.
Chemical Signaling and Neuromodulation: Neurotransmitters and hormones influence mood, motivation, and cognition, adding layers of complexity to information processing.
Embodied Cognition: The brain doesn’t operate alone; it constantly interacts with the body and environment, grounding cognition in sensory and motor experiences.

These complexities allow for consciousness, subjective experiences, and a depth of understanding that current AI models cannot replicate.

What True Intelligence Needs to Be

To achieve AGI, an artificial system must have several key attributes:

Reasoning and Problem-Solving: The ability to apply logic, understand cause and effect, and solve new problems without explicit prior examples.
Learning from Minimal Data: Humans often learn concepts from few examples. AGI should similarly generalize from limited data.
Contextual Understanding: Grasping the broader context in which information exists, including cultural, historical, and situational factors.
Adaptability: The capacity to adjust to new environments and situations dynamically.
Consciousness and Self-Reflection: Some argue that a level of self-awareness is necessary for true general intelligence.
Common Sense: An inherent understanding of how the world operates, which guides expectations and interpretations of new information.
Emotional and Social Intelligence: Recognizing and appropriately responding to emotional cues, essential for meaningful interactions.

Achieving these attributes requires more than data and computational power; it needs a fundamentally different approach to AI design.

The Limits of Transformer Architecture in Achieving AGI
Today’s AI models, like GPT-4, are built on Transformer architecture, which is great at recognizing patterns in large datasets and predicting the next word in a sequence. The Transformer model uses a mechanism called self-attention to weigh the importance of different words in a sentence, enabling the generation of contextually appropriate responses.

Their “understanding” is a reflection of patterns, not cognition.
However, Transformers have inherent limitations:

Lack of Deep Understanding: They do not comprehend the meaning behind data; they detect statistical patterns without true insight.
No Genuine Reasoning: Transformers cannot perform logical reasoning as humans do; they cannot infer beyond their training data.
Static Learning: Once trained, these models do not learn from new experiences in real-time; they require retraining to update their knowledge.
Limited Context: They process information within a limited context, struggling with tasks requiring long-term dependencies or extensive background knowledge.
Absence of Embodiment: Without sensory experiences or interaction with the physical world, they lack the grounding necessary for understanding context as humans do.

Why Transformers May Not Be Key to AGI
While Transformers can generate fluent and often insightful text, they aren’t designed to achieve AGI. Here’s why:

Predictive Power, Not Comprehension: Transformers predict what comes next based on data patterns, not on an understanding of the world or the context.
No True Understanding: They may generate text that makes sense, but they don’t understand the concepts they’re discussing. It’s all based on pattern matching and .
No Real Reasoning or Problem-Solving: True intelligence involves problem-solving that’s flexible and adaptive. Transformers can’t reason through problems or adapt to new situations beyond their training data.
Dependency on Data, Not Experience: Human intelligence grows through experience and learning. Transformers, on the other hand, rely solely on data they’ve been trained on. They don’t evolve or learn from new experiences.
Creativity vs. Mimicry: AI-generated creativity is just a remix of existing ideas—it’s not the same as human creativity, which draws on personal experiences, emotions, and original thinking.

What’s Needed for AGI? A New Approach
AGI will need more than just powerful models and bigger datasets. It requires an approach that goes beyond pattern recognition to incorporate symbolic reasoning, flexible memory structures, and adaptive learning mechanisms. AGI must be able to understand the world, reason through problems, and learn in real-time from experience—much like humans do.

Multimodal Learning and Understanding

One crucial aspect is multimodal learning, where an AI system processes and integrates information from various sources such as text, images, audio, and sensory data. Humans perceive the world through multiple senses, allowing for a richer and more grounded understanding of context. By emulating this, AI can form a more comprehensive picture of its environment. For example, combining visual data with textual information can help an AI understand concepts that are difficult to grasp through text alone.

Multimodal learning enables AI to:

Develop Contextual Awareness: By integrating different types of data, AI can understand the nuances of situations, leading to more accurate interpretations.
Enhance Problem-Solving: Access to diverse information sources allows AI to draw connections between disparate concepts, fostering creativity and innovation.
Improve Interaction: An AI that understands speech, gestures, and visual cues can interact more naturally with humans.

Adaptive Learning and Continuous Improvement

Another essential component is adaptive learning. Unlike current models that require retraining on new data, AGI should learn continuously from new experiences, updating its knowledge base in real-time. This involves developing algorithms that allow the AI to adjust its behavior based on feedback from its environment.

Adaptive learning allows AI to:

Personalize Responses: Tailoring interactions based on past experiences with users.
Learn from Mistakes: Adjusting strategies when previous actions didn’t yield desired results.
Stay Relevant: Keeping knowledge up-to-date without manual intervention.

Flexible Memory and Knowledge Representation

AGI will also need flexible memory systems that can store and retrieve information efficiently. This isn’t just about holding vast amounts of data but about organizing knowledge in a way that supports reasoning and inference. Incorporating symbolic reasoning—where AI manipulates symbols representing concepts and relationships—can enhance understanding and decision-making.

Flexible memory enables AI to:

Connect Concepts: Relate new information to existing knowledge.
Reason Logically: Use stored knowledge to infer conclusions.
Plan Strategically: Remember past actions to inform future decisions.

Understanding Causality and Reasoning

To reason effectively, AGI must understand causality—the relationship between cause and effect. This requires moving beyond models that only recognize correlations to ones that can infer causal relationships. By understanding why things happen, an AI can make predictions about future events and plan actions to achieve specific goals.

Understanding causality helps AI to:

Predict Outcomes: Anticipate the consequences of actions.
Diagnose Problems: Identify root causes rather than just symptoms.
Make Informed Decisions: Choose actions based on likely effects.

A New Architecture from the Ground Up

These requirements suggest that we need new AI architectures built from the ground up, rather than just scaling existing models. Such architectures would:

Integrate Multiple Learning Paradigms: Combine deep learning with symbolic reasoning and other approaches.
Emulate Human Cognitive Processes: Model aspects of human thought, such as memory, attention, and perception.
Facilitate Continuous Learning: Allow the system to adapt and grow without retraining from scratch.

Developing this new approach involves interdisciplinary research, drawing from neuroscience, cognitive science, computer science, and other fields. It’s about creating AI systems that don’t just process data but understand and interact with the world in a meaningful way.

By focusing on multimodal learning and adaptive systems, we can build AI that learns from its environment and experiences, much like humans do. This would mark a significant step toward achieving AGI.

The Challenge of Scaling AI: Power vs. Intelligence
As AI models like GPT-4 grow in complexity, they require more computational power. NVIDIA’s latest GPUs, such as the H200, are designed to handle the enormous amounts of data these models need. However, the question remains: does more computational power bring us closer to true intelligence, or are we just making more powerful machines that still can’t reason or understand?

Scaling AI doesn’t automatically mean achieving intelligence. The ability to process massive datasets and generate highly accurate predictions based on statistical patterns doesn’t equate to real understanding. More computational power allows AI to mimic intelligence more convincingly, but it doesn’t enable it to reason, adapt, or genuinely comprehend the world. We can make AI models faster, more accurate, and more efficient at pattern recognition—but without fundamental breakthroughs in how these models process and apply knowledge, we won’t have true AGI.

The Dilemma: More Computing Power vs. Real Intelligence
We’ve reached a point where we have the computational resources to train larger, more complex AI systems, but scaling AI doesn’t mean we’ve solved the problem of intelligence. Even with massive computational power, today’s models still can’t think or reason the way humans can. They can recognize patterns, but they lack the flexibility, creativity, and problem-solving abilities that define true intelligence.

The more computing power we apply to current models, the more sophisticated their outputs become—but they still operate based on patterns and predictions. We’re pushing the boundary of how well AI can mimic human behaviors, but we’re still far from creating machines that can understand the context of their actions, reason through complex scenarios, or adapt to new and unforeseen challenges. The more we scale AI, the more we face the paradox: we can build bigger, faster, and more powerful models, but we don’t yet have the architectural breakthroughs needed to create true intelligence.

Nuclear Power for AI: What It Will Take to Power the Future
As the demand for massive computational power grows to fuel AI advancements, tech companies are looking to secure reliable, high-output energy sources. Microsoft, for instance, has announced plans to hire experts in nuclear technology to help develop and implement nuclear energy solutions for its energy-intensive operations.

While there haven’t been reports of Microsoft striking a deal to restart the Three Mile Island nuclear power plant specifically, the company’s move highlights a broader industry trend.

The energy demands of training and running advanced AI models are enormous, and traditional power sources may not suffice in the long term. Nuclear energy presents a potential solution due to its ability to provide a consistent and powerful energy supply with lower carbon emissions compared to fossil fuels.
However, leveraging nuclear power for AI brings its own set of challenges. Restarting dormant nuclear facilities or building new ones requires significant investment, rigorous safety protocols, and public acceptance. The legacy of incidents like the 1979 partial meltdown at Three Mile Island underscores the importance of safety and transparency in any nuclear endeavor.

The balance between powering the next generation of AI and ensuring environmental and safety standards is delicate.

Conclusion: Rethinking AI’s Path to AGI
Today’s AI models like GPT-4 excel in several areas:

Pattern Recognition: They can identify and replicate complex patterns in data faster and more accurately than humans.
Data Processing: AI can handle vast amounts of information, providing insights and analysis far beyond human capacity.
Language Generation: These models are adept at creating text that is grammatically correct and contextually relevant, useful for tasks like writing assistance, customer service, and content creation.
Automating Routine Tasks: AI excels at automating repetitive and rule-based tasks, freeing humans for more creative and strategic activities.

While we’ve made incredible progress with AI, it’s clear that the current approach of scaling up models and increasing computational power won’t lead us to AGI. True intelligence involves more than just mimicking human-like responses; it requires deep understanding, abstract reasoning, and the ability to learn from real-world experience. We need to shift from creating more complex models to developing systems that can think critically, solve new problems, and adapt flexibly to different contexts.

The next step in AI development will require a new paradigm—one that moves beyond pattern matching and predictive text to include reasoning, abstract thinking, and adaptive learning. This shift will require breakthroughs not only in algorithms and hardware but in the very way we conceive of intelligence itself. Until we make that leap, AI will continue to be a powerful tool, but it won’t achieve the true, flexible intelligence we imagine for AGI.
