Narrow (Weak) AI

Narrow AI, or weak AI, is the most common today. It’s made for specific tasks and does well in those areas. For instance, Apple’s Siri, launched in 2011, is great at understanding voice commands and helping with tasks.

Reactive machines, a part of narrow AI, act based on what they see or hear right then. IBM’s Deep Blue, which beat chess champion Garry Kasparov in the 1990s, is a good example. These systems don’t learn from past experiences but are very good at what they do.

Artificial General Intelligence (AGI)

Artificial general intelligence agi wants to be as smart as humans in many areas. Though AGI is just an idea, scientists are trying to make AI that can understand and feel emotions, called Theory of Mind AI.

Superintelligent AI

Superintelligent AI is a dream of the future where machines are smarter than humans in everything. This idea is more like science fiction for now, as we haven’t even reached AGI yet.

AI Type	Capabilities	Real-world Examples
Narrow AI	Task-specific, limited scope	Siri, Netflix recommendations
AGI	Human-level intelligence (theoretical)	None yet
Superintelligent AI	Beyond human capabilities (hypothetical)	None yet

As AI keeps getting better, it’s important to keep up with these different kinds and their effects on society and work.

How Artificial Intelligence Works

AI systems handle big data to make choices and solve problems. They use complex algorithms to look through information and spot patterns. This lets them think and solve problems like humans do.

At its heart, AI relies on machine learning. This tech lets computers learn from experience without being told how. The more data it gets, the better it gets at its job.

Here’s a breakdown of how AI works:

1. Data collection: AI systems gather vast amounts of information from various sources.
2. Data processing: The collected data is cleaned and organized for analysis.
3. Pattern recognition: AI algorithms identify trends and relationships within the data.
4. Decision making: Based on the patterns found, the AI makes predictions or takes actions.

Different types of AI use unique methods. For instance, neural networks are like the human brain to process info. Deep learning models use many layers of these networks to handle tough tasks.

AI Type	Function	Application
Machine Learning	Learns from data without explicit programming	Recommendation systems
Natural Language Processing	Understands and generates human language	Virtual assistants
