What are the 4 types of AI technology?

The four commonly referenced types of AI technology are based on capability and functionality. Here’s a clear breakdown:

1. Reactive Machines

• The most basic form of AI.
• No memory, cannot learn from past experiences.
• Respond only to current inputs.
• Example: IBM’s Deep Blue chess computer.

2. Limited Memory

• Most AI systems today fall into this category.
• Can use past data for a short time to make decisions.
• Example: Self-driving cars, chatbots (like me), recommendation systems.

3. Theory of Mind (Future / Experimental)

• AI that understands emotions, beliefs, intentions, and can socially interact.
• Still in research; not yet achieved.

4. Self-Aware AI (Hypothetical)

• AI that has consciousness, self-awareness, and independent thoughts.
• Does not exist yet.
