6.3. Types of AI

Types of AI can be categorized based on their capabilities:

1. Narrow AI (Weak AI):

   • Designed for a specific task.
   • Example: Siri, Alexa, Google Translate.

2. General AI (Strong AI):

   • Hypothetical AI that can perform any intellectual task that a human can do.
   • Still under research.

3. Super AI:

   • A level beyond human intelligence.
   • Currently theoretical and subject to ethical debates.

This chunk introduces the categorization of AI based on capabilities.

• Narrow AI, also known as Weak AI, is designed to perform a specific task, such as virtual assistants like Siri and Alexa or translation applications like Google Translate. They are proficient at their designated tasks but cannot perform beyond them.
• General AI, or Strong AI, is still a theoretical concept that refers to machines capable of performing any intellectual task a human can, demonstrating the same level of intelligence as humans. Current research focuses on making this a reality.
• Super AI represents an advanced stage of AI that exceeds human intelligence and cognitive abilities. This form of AI is primarily theoretical and raises ethical dilemmas regarding its creation and control.

Think of Narrow AI like a skilled chef who specializes in Italian cuisine; they can cook exceptionally well but would struggle to prepare a full-course meal from a different cuisine, such as Japanese. General AI would be the equivalent of a 'master chef' who can cook any type of cuisine, while Super AI compares to a culinary genius who can invent entirely new dishes and cooking methods beyond current human understanding.

AI can also be categorized based on functionalities:

1. Reactive Machines:

   • Respond to present inputs only.
   • No memory.
   • Example: IBM’s Deep Blue.

2. Limited Memory:

   • Can use past data to make decisions.
   • Example: Self-driving cars.

3. Theory of Mind (Future AI):

   • Can understand human emotions and intentions.
   • Still under development.

4. Self-Aware AI:

   • AI with self-consciousness and awareness.
   • Completely theoretical.

This chunk highlights the categorization of AI based on its functionalities.

• Reactive Machines like IBM's Deep Blue chess computer can only react to the current situations without any historical knowledge, meaning they don't remember past games or experiences, which limits their adaptability.
• Limited Memory systems can draw on past experiences to make decisions, similar to how a self-driving car uses past data (like previous routes) to navigate traffic.
• Theory of Mind AI is a future concept, aimed at machines that can comprehend human emotions and social dynamics, allowing for more intuitive interactions.
• Self-Aware AI is another future concept where AI possesses consciousness and self-awareness, though this remains hypothetical and not yet achieved.

Imagine a child's toy robot that only responds to immediate actions as a Reactive Machine; it follows commands but cannot recall past instructions. In contrast, think of a chatbot that learns from previous conversations with customers as a Limited Memory system, adapting its responses over time. Theory of Mind and Self-Aware AI would be like having a robotic companion that not only understands what makes you happy or sad but can also reflect on its own feelings and the implications of those feelings.
