What is AI?
Defining artificial intelligence, narrow vs general vs super AI
Artificial Intelligence (AI) is the simulation of human intelligence by machines — enabling computers to perform tasks that would normally require human cognition: learning, reasoning, problem-solving, perception, and language understanding.
At its core, AI is a broad field of computer science concerned with building systems that can act intelligently in the world, whether that means recognising a face, recommending a movie, driving a car, or generating a poem.
Key Points
- AI is the broadest umbrella — it encompasses Machine Learning and Deep Learning as subfields
- Narrow AI (ANI): excels at one specific task (chess, image recognition, voice assistants)
- General AI (AGI): hypothetical human-level intelligence across all tasks — does not yet exist
- Super AI (ASI): hypothetical AI surpassing human intelligence in every domain
- AI systems learn from data, rules, or a combination of both
- Key AI capabilities: perception, reasoning, planning, natural language, learning, and action
| AI Type | Description | Example |
|---|---|---|
| Narrow AI (ANI) | Optimised for a single task | Siri, AlphaGo, spam filter |
| General AI (AGI) | Human-level reasoning across domains | Theoretical — not achieved |
| Super AI (ASI) | Surpasses human intelligence | Theoretical — science fiction |
Real-World Example
Every time Netflix recommends a show, Google Maps reroutes you around traffic, or your email client moves spam to junk — that is narrow AI in action. Modern AI runs on billions of devices and affects nearly every industry.
