Types of AI

While the concept of Artificial General Intelligence (AGI), an AI as intelligent as a human, is still largely theoretical, we've made significant strides in developing and implementing various forms of Narrow AI (ANI).

Here are some of the most common types of AI being used today:

1. Reactive Machines: These are the most basic form of AI, capable of reacting to present situations but unable to learn or form memories. Examples: Early chess computers, classic video game opponents.
2. Limited Decisions: These AI systems can use past data to inform their decisions, but they cannot store this information for long-term use. Examples: Self-driving cars, which use sensor data to navigate but don't store this data permanently.
3. Theory of Mind (Hypothetical): This level of AI would require understanding and reasoning about mental states, including beliefs, desires, and intentions. Examples: Not yet achieved, but would be necessary for truly natural human-computer interaction.
4. Self-Awareness (Hypothetical): This is the highest level of AI, where machines would have consciousness and self-awareness. Examples: Purely hypothetical at this stage.
