Narrow AI is the most common type of AI we interact with daily.
2. General AI (Strong AI)
General AI, or Strong AI, is a more advanced form of AI that can understand, learn, and apply intelligence across a broad range of tasks, much like a human. While we’re still far from achieving true General AI, researchers are working toward creating systems that can exhibit cognitive abilities comparable to human thinking.
A General AI system would:
- Reason about the world
- Understand abstract concepts
- Solve problems in unfamiliar situations
- Learn new tasks without specific programming
As of now, General AI remains theoretical, and most AI applications fall into the category of Narrow AI.
3. Artificial Superintelligence (ASI)
Artificial Superintelligence (ASI) refers to AI that surpasses human intelligence in all aspects, from creativity and problem-solving to emotional intelligence and decision-making. ASI would be capable of autonomously solving complex problems, potentially outperforming humans in every field.
Though ASI is a topic of much debate and speculation, it remains a future concept. Experts disagree on when, or even if, Artificial Superintelligence will ever be achieved.
