Why AI Models Can't Achieve General Intelligence — Yet


In the realm of artificial intelligence, the quest for general intelligence—an AI that mimics human-like reasoning and cognition—remains one of the most ambitious goals. Today, AI excels in specialized tasks like computer vision and language processing, but we’re still far from developing machines that can reason across the full spectrum of human experience. One key reason for this gap is that these AI models lack something fundamentally important: the integrated, multisensory experience that underpins human reasoning.

Human Reasoning: A Blend of Sensory Inputs

Human intelligence is not just about logic or data processing—it’s about how we experience the world. Our reasoning emerges from a complex interaction of sensory information, memory, emotions, and cognitive processing. Every moment, our brains are receiving stimuli from multiple sensory channels: sight, sound, touch, taste, and smell. Our brains integrate these sensory inputs in real-time, which informs our thoughts, decisions, and actions.

For example, imagine you're walking in a park. Your eyes are processing visual cues: trees, people, and paths. Your ears are picking up the sounds of birds or distant conversations. Your feet are feeling the ground beneath you, helping you gauge distance and movement. These sensory inputs are constantly being synthesized in the brain, helping you navigate the world, understand your environment, and make decisions.

Memory plays a critical role too. Past experiences—whether it's remembering how to avoid a puddle or recalling what a tree looks like from previous visits—also shape your reasoning. So, human reasoning is more than just processing data; it’s about understanding context, adapting to new situations, and making decisions based on an evolving pool of sensory data and memories.

The Limits of Current AI Models

AI today is largely focused on specialized tasks, and two of the most prominent areas are computer vision and language processing.

  • Computer vision models analyze images or video data, recognizing patterns, objects, and even faces. They excel at tasks like identifying objects in pictures or detecting anomalies in video feeds. But these models are focused solely on visual input. They do not experience the world in the way humans do—they cannot "feel" the texture of objects or "hear" the sounds in the environment that might inform their understanding of a situation.

  • Language models like GPT-3 are trained to process and generate text. These models excel at understanding language, answering questions, and generating coherent sentences. However, they don’t truly "understand" the world—they don’t experience sensory inputs or physical environments. They base their responses on patterns they've learned from vast amounts of text data, not on direct interaction with the world.

Despite their successes, both computer vision and language models lack the ability to integrate multiple forms of sensory data in real time, as the human brain does. These models excel in their domains but are unable to reason across them or understand broader, context-dependent situations in a way that humans can.

Why AI Needs More Than Just Vision and Language

To approach general intelligence, AI would need to do more than just process images or text. It would need to integrate sensory inputs, understand context, and reason based on a rich pool of experiences. Consider this:

  • Embodiment: Humans don’t just think abstractly—we interact with the world physically. Our motor skills, like moving our arms, walking, and even feeling objects, contribute to our understanding of the world. For AI to reason like humans, it would need a body that can sense and interact with its environment.

  • Multimodal Learning: To match human intelligence, AI would need the ability to process inputs from multiple sensory channels—vision, sound, touch, and even possibly smell and taste. A computer vision model may recognize a cup, but a human can not only identify the cup but also feel its texture, hear it clink against a surface, or smell the coffee inside. This combined sensory input leads to richer reasoning.

  • Contextual Understanding: Humans don’t just react to isolated stimuli—they understand the context around them. If you see someone smile, you might infer happiness, but if you hear a joke right before, you might infer that the smile is related to the humor. AI models often lack this contextual flexibility and fail to adapt when the scenario changes.

The Road to General Intelligence: A Long Way to Go

The ultimate goal in AI research is to create Artificial General Intelligence (AGI), an AI system that can perform any intellectual task that a human can. However, as it stands, AGI would require much more than the current computer vision and language models. It would need multimodal integration, embodied experiences, and the ability to reason and adapt to an ever-changing world.

While AI systems today are making impressive strides in narrow tasks, the journey to true general intelligence remains a complex challenge. AI will need to develop in ways that mirror the human brain—not just processing information in isolated domains but integrating it across senses, contexts, and experiences.

The road ahead is long, but as AI researchers work to build more multimodal systems and explore the embodiment of machines, we may one day come closer to building machines that think—and experience—the way humans do.

The Eternal November

 The concept of Eternal September originated from the internet's early days, when AOL started offering easy internet access to a massive number of people in September 1993. This influx of new users overwhelmed the existing online communities, changing the dynamics of the internet forever. What was once a niche, controlled space became open to everyone, leading to a period of chaotic growth and learning curves. Now, when we think about AI's public emergence — especially large language models like GPT (and its successors) becoming publicly accessible and widely used — we might say we're experiencing a similar phenomenon, except this time in the realm of artificial intelligence. The "Second Eternal September" of AI In a way, we are indeed living through something like a **second Eternal September**, but this time for AI: 1. Mass Adoption of AI Tools: With platforms like ChatGPT, DALL·E, and MidJourney becoming widely accessible to the public, AI is no longer confine...

The Split in OOP: Compositional vs. Genealogical Design

The Two Faces of Object-Oriented Programming: Inheritance vs. Composition Object-oriented programming (OOP) has evolved over the decades, branching into two distinct paradigms that shape how developers model and structure their systems: genealogical (inheritance-based) OOP and compositional (composition-over-inheritance) OOP. While both approaches fall under the OOP umbrella, they reflect fundamentally different philosophies on how to build and organize behavior. 🔹 Genealogical OOP (Classical Inheritance) This is the traditional, textbook model of OOP. In this approach, classes form hierarchies where child classes inherit behavior and structure from parent classes—a lineage that resembles a family tree. This is the familiar “is-a” relationship. Common Languages : Java, C++, classic Python, Ruby Key Characteristics : Emphasis on class hierarchies Behavior is reused via subclassing Polymorphism is achieved through inheritance Often leads to deep class trees that can becom...

Spinnin’ and Steppin’: Traversing 3D Space with SpinStep

Image
The 3D Tree Traversal Problem Spatial data structures are everywhere — from game engines to robotics and scientific simulations. But while traditional trees like quadtrees, octrees, and BSP trees do well in axis-aligned or position-based contexts, they begin to falter when direction and orientation become the dominant parameters. How do you traverse a hierarchy not by going "left" or "down," but by rotating your point of view? Enter SpinStep SpinStep is intended to be a lightweight traversal framework based on quaternions — mathematical structures that represent 3D rotations. Rather than following nodes based on positional distance, SpinStep selects branches according to their angular proximity to the current orientation. This creates a new traversal metaphor: not stepping from point A to B, but rotating into the next part of the tree. At its core, SpinStep implements a directional depth-first iterator. It uses quaternions to determine whether a child node is reacha...
