Today, we'll explore two primary types of AI: Narrow AI and General AI. Who can remind us what Narrow AI refers to?
I think Narrow AI is focused on one specific task, like a voice assistant?
Correct! Narrow AI, or weak AI, specializes in a single task. Can anyone give me an example?
Spam filters in emails could be one.
Exactly! Now, what about General AI? How does it differ?
Is it the AI that can do any intellectual task like a human?
Yes, that's right! General AI, or strong AI, is still under research and aims to mimic human-like intelligence.
So, what is Super AI then?
Super AI refers to a future form of AI that would be smarter than humans. Right now, it's hypothetical.
In summary, Narrow AI is task-specific, while General AI aims for human-like problem solving, and Super AI is a future concept.

Now, let's shift our focus to the functionality of AI. What are the two main types of AI we classify by functionality?
Reactive Machines and Limited Memory?
Close! There are Reactive Machines, Limited Memory, Theory of Mind, and Self-Aware AI. Let's start with Reactive Machines.
Reactive Machines don't have memory, right? They just respond to immediate inputs?
Exactly! They perform simple tasks using set rules, like a chess-playing AI. What about Limited Memory?
That would be AI that learns from past experiences, like self-driving cars?
Perfect! Limited Memory AI uses past data to make informed decisions. Now, can anyone explain the Theory of Mind?
Is it when AI understands human emotions and social interactions?
Exactly right! The Theory of Mind is still a goal for future AI development. Finally, what's the concept of Self-Aware AI?
It’s a theoretical AI that's conscious of its existence?
Yes! It's currently purely theoretical. Great job today! We covered a lot about AI types.

Quick Overview
Standard
In this section, we explore the various types of AI, distinguishing them by capability—including Narrow AI, General AI, and Super AI—and by functionality, such as Reactive Machines, Limited Memory, Theory of Mind, and Self-Aware AI, highlighting examples and their significance.
Detailed
Types of AI
Artificial Intelligence (AI) can be categorized based on two primary criteria: capability and functionality. Understanding these types helps clarify the current state of AI technology and its potential future developments.
By Capability
- Narrow AI (Weak AI): This type of AI is specialized in one specific task. Most AI applications, such as spam filters in emails or voice assistants, fall under this category.
- General AI (Strong AI): This refers to AI systems that have the ability to perform any intellectual task that a human can do. Currently, this type of AI is still under research and development.
- Super AI: A hypothetical form of AI that would surpass human intelligence and capabilities. This level of AI has not yet been achieved.
By Functionality
- Reactive Machines: These systems operate on basic data input and output, with no memory. A classic example is AI that plays chess.
- Limited Memory: AI in this category can use past data to inform decisions. Self-driving cars utilize this ability to navigate safely by learning from past driving experiences.
- Theory of Mind: This is a future goal of AI—that is, to enable systems to understand human emotions, beliefs, and interactions.
- Self-Aware AI: This is purely theoretical at the moment and refers to AI that possesses self-consciousness and awareness.
Understanding these classifications is essential as we navigate the growing influence of AI in society.

Chapter Content
AI can be categorized based on capability and functionality:
By Capability:
1. Narrow AI (Weak AI):
- Specialized in one task.
- Most current AI systems fall under this.
- Example: Spam filters in email.
2. General AI (Strong AI):
- Performs any intellectual task like a human.
- Still under research.
3. Super AI:
- Hypothetical AI smarter than humans.
- Not yet achieved.
Detailed Explanation
AI can be divided based on its capability to perform tasks.
1. Narrow AI (Weak AI): This type of AI is designed for a specific task and excels at it. Most of the AI systems we interact with today, like spam filters which separate unwanted emails from our inbox, are examples of Narrow AI.
- General AI (Strong AI): This advanced form of AI would have the ability to understand and perform any intellectual task that a human can do. However, this type of AI is still being researched and does not yet exist.
- Super AI: This is a theoretical concept referring to a future AI that surpasses human intelligence in all aspects. It remains an idea for future exploration and has not been realized.
Examples & Analogies
Think of Narrow AI as a specialized athlete, like a sprinter who is incredibly fast but can only run races. In contrast, General AI would be like a multi-sport athlete who excels in various disciplines, while Super AI is like a hypothetical champion who could outperform every athlete in any sport imaginable.

By Functionality:
1. Reactive Machines:
- Simple task performers, no memory.
- Example: Chess-playing AI.
2. Limited Memory:
- Can use past data for decisions.
- Example: Self-driving cars.
3. Theory of Mind:
- Understands emotions, beliefs, and interactions (future AI goal).
4. Self-Aware AI:
- Conscious and self-aware (purely theoretical currently).
Detailed Explanation
AI can also be categorized based on its functionalities in performing tasks.
1. Reactive Machines: These AIs operate solely on the present and cannot use past experiences to inform current actions. For example, chess-playing AI analyzes the current board position without remembering prior games.
- Limited Memory: This type of AI can refer to past experiences to inform decisions. Self-driving cars are a good example as they gather and process previous driving data to navigate safely.
- Theory of Mind: This is an aspirational concept where AI would be able to understand human emotions and beliefs, enabling more nuanced interactions. This goal represents the next evolution of AI functionality.
- Self-Aware AI: This remains a theoretical construct that symbolizes a level of consciousness akin to humans. Currently, such AI does not exist.
Examples & Analogies
Consider Reactive Machines as a calculator that gives you answers based only on the numbers you input right now, with no memory of past calculations. Limited Memory is like an experienced tutor who remembers your previous test scores and tailors your lessons accordingly. Theory of Mind reflects the goal of making AI more relatable, similar to how a trusted friend understands your emotions. Lastly, Self-Aware AI is akin to a character in a sci-fi movie who possesses self-awareness and can think independently, a fascinating concept yet to be realized.
