The Human Factor: What AI Still Needs to Learn from People

Artificial intelligence (AI) has come a long way in recent years. From beating human champions at games like chess and Go, to driving cars autonomously, to generating human-like conversations, AI is increasingly encroaching on activities that were once considered exclusively human. However, there are still many things that AI lacks when compared to human intelligence and abilities. In this comprehensive guide, we’ll explore the key areas where AI still needs to learn from people.

Introduction

The rapid advances in artificial intelligence, machine learning and neural networks have led many to speculate that AI may one day exceed human capabilities. Some even predict that superintelligent AI could pose an existential threat to humanity. However, most experts agree that we are still far from developing truly human-like artificial general intelligence.

AI excels at narrow, limited tasks like playing specific games, transcribing speech, or scanning images. But when it comes to general intelligence, creativity, empathy, ethics, and other capacities that come naturally to people, AI still has a lot to learn. As advanced as modern AI systems are, they lack the nuance, contextual understanding, general knowledge, and reasoning ability that even a young child possesses.

So while AI is superhuman at some things, it remains subhuman at many others. By exploring the limitations of current AI and the contrasts with human cognition, we can shed light on the inner workings of the human mind and also chart a path for developing more human-like artificial intelligence.

Key Areas Where AI Needs to Improve

Understanding Context and Nuance

Humans effortlessly interpret subtle context cues and nuances of language that enable us to understand text and speech. We grasp sarcasm, metaphors, ambiguities, idioms and more based on contextual clues. AI, on the other hand, takes words literally and struggles with the subtleties of human communication. It fails to comprehend nuance and double meanings.

Teaching AI systems to understand natural language context remains an unsolved challenge. Without the ability to discern sarcasm or metaphors, parse ambiguous phrases, or grasp implied meaning, AI cannot achieve true language understanding.

General Knowledge and Common Sense

People possess vast stores of general world knowledge and common sense accumulated over a lifetime of experiencing the world. This contextual understanding is what enables us to have intelligent conversations on a limitless array of topics.

AI systems today have very limited general knowledge. While machine learning algorithms can extract statistical patterns from massive datasets, this is not the same as human-like concept understanding. AI lacks the top-down general knowledge and bottom-up sensory understanding of the world that people take for granted.

Endowing AI with general knowledge graphs and common sense reasoning remains an open research problem. Narrow AI today is ignorant about basic facts, unable to answer simple questions, and lacks the sound reasoning abilities that come naturally to people.

Creativity and Imagination

Human intelligence excels at creativity, imagination, and ideation. We can envision fictional scenarios, imagine solutions to open-ended problems, and create art, literature and music that sparks emotion. AI has achieved little in these areas so far.

The stunning creativity of the human mind arises from our lived experiences, emotions, memories, and rich mental models of the world. But today’s neural networks have no experiences to draw upon. Without a lifetime of sensations, understanding, emotions, and memories, AI lacks the ingredients essential for creativity.

While neural networks can generate paintings or continue a story prompt, the results are devoid of true depth, emotion and meaning. AI has a long way to go before it can match the creative capabilities of even a young child.

Social Intelligence and Emotional IQ

Interacting with others in social situations requires intuition, etiquette, empathy, and theory of mind. Humans (with the exception of some psychological conditions) easily recognize emotions in others from facial expressions, body language and tone of voice. We understand that others may have different mental states than our own.

In contrast, AI algorithms today have zero inherent social intelligence or emotional IQ. Systems can be trained to recognize emotions, but they do not naturally understand social cues or possess any empathy. Human emotional intelligence emerges from our evolutionary history as highly social creatures dependent on reading others’ mental states to survive and thrive. AI lacks this intrinsic social nature.

The social ineptitude of today’s AI would be like an alien species with no concept of human norms. Social intelligence and emotional IQ remain almost completely absent in machines.

Ethics, Morals and Values

People have an intrinsic system of ethics that guides our decisions and behaviors. Empathy, integrity, fairness, and care for others are human values present in children without any training needed. We learn and internalize moral values from parents, society, and religion. AI systems today have no inherent ethics, morals or values. They simply optimize whatever goal or metric they are programmed to maximize.

There are initiatives to train AI systems in ethical reasoning and equip them with top-down rules. But this is very different from the innate empathy, ethics and values that guide human behavior. We do not yet know how to instill genuine ethical reasoning in AI. It remains an open challenge.

Reasoning, Critical Thinking and Problem Solving

Human thought excels at reasoning, critical thinking and complex problem solving in open-ended situations with ambiguous, incomplete or contradictory information. Our general intelligence allows inferring answers, weighing alternatives and making judicious decisions.

Today’s AI, in contrast, is specialized for narrow tasks with fixed rules and objectives. Systems rely on pattern recognition within training data rather than reasoning from first principles. They falter outside narrowly defined domains. AI cannot yet exhibit the flexible reasoning and problem solving that comes naturally to people.

Developing AI with more broad capabilities for reasoning and critical thinking in the messy real world remains an ongoing research goal.

Learning Quickly from Limited Experience

Humans are capable of quickly learning new skills and concepts from very few examples. Show a person a single image of an unfamiliar object, and they can recognize other instances, imagine views from different angles, and understand related objects. In contrast, machine learning algorithms require thousands to millions of training examples to perform tasks like object recognition.

The human ability for one-shot or few-shot learning arises from our general world knowledge and inductive biases. We can correctly guess how an unfamiliar animal might behave based on our experience with related objects. AI today lacks this inductive reasoning ability and struggles to generalize from limited data.

Rapid learning from small data remains an important open challenge and key difference from human intelligence. Future AI systems will need more efficient learning algorithms and knowledge transfer abilities to acquire new skills as quickly as people can.

Common Sense Understanding of the Physical World

People intuitively understand basic properties of the physical world such as object permanence, rigid body mechanics and natural phenomena. This innate “naive physics” enables even infants to interpret scenes, predict how objects behave, and learn cause-and-effect relationships.

AI systems today have no inherent concept of the dynamics of the physical world. Algorithms can learn patterns from data but lack human instinctive understanding of forces, materials, light, shadows, etc. As a result, AI can fail at tasks that involve interacting with or reasoning about the 3D world in ways that come naturally to people.

Imbuing AI with more human-like intuitions about fundamental physics and mechanics remains an open research problem to overcome the brittleness of today’s systems.

Intent, Deliberation and Planning

Unlike current AI systems that passively observe data, people exhibit active intelligence. Human cognition constructs mental models of the world used to consciously deliberate, set goals, formulate plans, and carry out actions with intent. Our agency and metacognition allow reflecting on our own knowledge and thought processes.

AI algorithms today lack any inherent goals, intentions, deliberation or metacognition. Systems are trained through passive pattern recognition, not active learning and planning. While algorithms can optimize behaviour to maximize a reward signal, this is not equivalent to human-like cognition, agency and introspection.

Developing AI that exhibits intent, planning, initiative, self-supervised learning, and metacognitive abilities remains an open challenge and key to achieving artificial general intelligence.

Why Closing the Gap Matters

Understanding the stark contrasts between human and machine cognition is not just an academic exercise. Continuing to push AI capabilities closer to human-level intelligence in areas like language, creativity, reasoning, ethics, and social skills should be a priority for AI research.

Narrow AI has achieved remarkable successes in specialized domains. But the limitations highlight how far we still have to go to achieve artificial general intelligence comparable to the flexible, well-rounded and multifaceted cognitive abilities of people.

Pursuing this challenge matters for several reasons:

• To realize the full potential of AI to assist and cooperate with humans, it needs to share more of our contextual understanding and reasoning abilities.
• Developing human-like social and emotional intelligence is key to integrating AI systems into human collaborations and roles.
• Teaching AI ethics, common sense and sound reasoning is essential to ensure reliable and safe behaviour as systems become more autonomous.
• Matching more facets of human intelligence will pave the way for general artificial intelligence.
• Understanding how the human mind works is fascinating scientific knowledge in itself with implications for fields like psychology, neuroscience and cognitive science.

The contrasts between today’s AI and natural human cognition highlight gaps but also a path forward. While fully replicating the breathtaking complexity of the human mind remains a long-term challenge, each step towards closing the gap represents progress. The brain’s capabilities evolved over millions of years; AI has only existed for decades. With sustained research mapping more human qualities into machines, the coming centuries will continue closing the gaps between biological and artificial intelligence.

Key Areas Where AI Exceeds Human Abilities

Thus far we have focused on capacities where AI trails human intelligence. For a balanced perspective, it is also important to highlight areas where AI has surpassed people:

• Calculation – AI can perform arithmetic and data analytics orders of magnitude faster and more accurately than humans.
• Game playing – AI has exceeded human skill at complex games like chess, Go and poker that involve planning and probability.
• Pattern recognition – Machine learning can spot subtle patterns in data that humans would never notice.
• Language translation – AI can translate between languages more fluently than all but the most skilled human experts.
• Object detection – Algorithms can locate and identify objects in images with superhuman accuracy.
• Data retrieval – AI can instantly retrieve information from vast databases many times larger than any human could memorize.

So while AI still struggles with many attributes of human intelligence, it has already surpassed people in various narrow domains. With continued exponential progress, AI may one day exceed human capabilities in more multifaceted areas as well.

Developing More Human-Like AI

Given the contrasts between human and machine intelligence, what strategies show the most promise for developing AI that better captures broad facets of human cognitive abilities? Here are some promising directions:

• Lifelong and multitask learning – Equip AI agents with more general world knowledge by training them on a wide diversity of tasks without siloed specialization.
• Cognitive architectures – Develop computational frameworks based on theoretical models of human cognition rather than pure black-box statistical learning.
• Memory networks – Augment neural networks with external memory stores that accumulate knowledge, akin to how people learn.
• Relational reasoning – Move beyond pattern recognition to infer new relationships and perform the kind of abstract reasoning people excel at.
• neuromorphic computing – Architect AI hardware modeled on the neural structure and signal processing of the human brain.
• Developmental learning – Mimic key stages of child development to achieve more human-like learning trajectories.
• Embodied cognition – Situate AI agents in simulated or physical environments to gather sensory experiences like people.
• Multimodal perception – Integrate multiple sensory inputs like vision, audio, touch, proprioception, etc to achieve more grounded understanding.
• Social learning – Develop socially interactive agents that learn by observing and cooperating with others.
• Curiosity and autonomy – Enable agents to set their own goals and autonomously explore and learn like human children.
• Theory of mind – Endow agents with models of others’ beliefs, desires, and intentions for more social intelligence.
• Inverse reinforcement learning – Discover intrinsic human values and ethics by modeling observed behavior.

This list highlights promising directions for reducing the gaps between human minds and artificial minds. While exclusively human characteristics like qualitative experience, emotion, and consciousness may remain elusive, continuing to map more human qualities into machines will still vastly expand AI capabilities.

Bridging these gaps matters not only for developing powerful general artificial intelligence, but also for gaining a deeper scientific understanding of the marvels of human cognition and intelligence.

Frequently Asked Questions

Does today’s AI pose a threat to humanity?

No, today’s AI systems are too narrow and limited to pose any existential threat to humanity. While concerns about highly advanced future AI are reasonable, today’s technology has no goals, values, or general intelligence and remains focused on well-defined tasks. Current hype about the dangers of AI vastly overstates actual capabilities. AI can, however, negatively impact society if used irresponsibly.

What are the main risks around AI safety?

The two main risks are 1) flawed objectives, where an advanced system optimizes harmful goals rather than beneficial ones, and 2) limited oversight, where autonomous systems behave in unintended ways without human supervision and feedback. However, these risks likely only apply to hypothetical advanced future AI, not today’s technology. Responsible development of human-compatible objectives and human-in-the-loop oversight can mitigate AI risks.

Can we build ethical AI systems?

Yes, instilling human ethical values in AI systems is an important research goal. Potential approaches include training AI through reinforcement learning on human moral judgments, formalizing ethics into constraints and rules, and embedding proxy objectives that encapsulate common values around fairness, safety and transparency. Integrating ethics requires ongoing collaboration between technologists, philosophers and social scientists.

Isn’t AI a threat to human jobs and work?

Like past innovations, AI will displace certain jobs but also create many new kinds of work and economic growth. Adaptation is needed, and the net effect on jobs is debatable. But a reasoned historical perspective suggests AI will not permanently end human labor. Many tasks still exceed AI capabilities. Regulation may be needed to reap the benefits of AI while mitigating harms.

Should there be more regulation around AI technology?

Reasonable oversight and regulation mechanisms are prudent to ensure ethical use of AI that respects human rights and shared values. Regulation is already emerging in domains like self-driving vehicles, medicine, and weapons systems. But overly restrictive regulations risk curtailing innovation and technological progress. The ideal policy balances public safety with continuing advancement.

When will we achieve human-level artificial general intelligence?

It is impossible to predict accurately, but most experts estimate human-level AI is at least decades away, though incremental progress will continue. The human brain evolved over millions of years, so matching its broad general capabilities in machines remains an immense technical challenge requiring fundamental conceptual breakthroughs, not just faster hardware. But humanity’s first steps toward AGI are now underway.

Conclusion

The contrasts between human and artificial intelligence suggest AI still has a long path ahead to equal the cognitive abilities that come naturally to people. While today’s systems excel in narrow domains, they lack the breadth, flexibility, context, knowledge, reasoning, ethics, social skills, and well-rounded intelligence of the human mind. However, the rapid advances in AI and neural networks indicate we are at the dawn of the journey towards artificial general intelligence.

By studying the shortcomings of modern AI versus human cognition, we chart a roadmap towards the development of broader, more human-compatible machine intelligence. And by reverse engineering the mechanisms underlying the fluid multifaceted intelligence of our own minds, we unlock deep scientific insights into the nature of biological cognition. Understanding the interplay between human and artificial intelligence remains one of the most fascinating and important frontiers of science and technology.
