Strong AI (Artificial General Intelligence)
Hypothetical artificial intelligence with human-level cognitive abilities across all domains of intelligence.
What is Strong AI?
Strong AI, also known as Artificial General Intelligence (AGI), refers to a hypothetical type of artificial intelligence that possesses human-level cognitive abilities across all domains of intelligence. Unlike Weak AI which is designed for specific tasks, Strong AI would have the capacity to understand, learn, and apply knowledge in any intellectual task that a human being can, including reasoning, problem-solving, creativity, and abstract thinking.
Key Characteristics of Strong AI
- General Intelligence: Ability to perform any intellectual task
- Human-Level Cognition: Comparable to human cognitive abilities
- Understanding: True comprehension of concepts and contexts
- Adaptability: Ability to learn and adapt across diverse domains
- Consciousness: Hypothetical self-awareness (debated)
- Transfer Learning: Applying knowledge from one domain to another
- Common Sense: Human-like general knowledge and reasoning
Strong AI vs Other AI Concepts
| Concept | Relationship to Strong AI | Key Differences |
|---|---|---|
| Weak AI | Current reality | Task-specific, no general intelligence |
| Strong AI (AGI) | Hypothetical human-level AI | General intelligence across domains |
| ASI | Potential evolution of Strong AI | Surpasses human intelligence |
| Human Intelligence | Benchmark for Strong AI | Biological rather than artificial |
