Americans interact with artificial intelligence (AI) products daily, from talking to Amazon’s Alexa to scrolling through Netflix recommendations. However, artificial intelligence is a broad term that encompasses a range of technologies.
Here are four types of AI, from the most basic to the entirely theoretical.
Reactive AI
Reactive AI is the most basic form of AI. It is designed to respond to inputs in a specific way. For example, an email spam filter is reactive AI. It is programmed to identify specific patterns in spam emails and block them.
Limited memory AI
Limited memory AI is more sophisticated than reactive AI. It can remember past events and learn from them.
For example, semi-autonomous vehicles use limited memory AI. They can use cameras and sensors to detect nearby traffic, pedestrians and stoplights, and they can store this information in their memory. This allows them to make smarter, safer decisions on the road.
Theory of mind AI
Theory of mind AI is even more sophisticated than limited memory AI. It can understand the thoughts and emotions of people and animals, and adjust its own behavior accordingly.
For example, some experts say that ChatGPT has demonstrated theory of mind, but many remain skeptical.
Self-aware AI
Self-aware AI is the most advanced form of AI. It would have its own thoughts, feelings and aspirations. Some would call it sentient.
While it has the potential to streamline many aspects of society, many fear that this AI could see humans as a threat and decide to take over.
At this point, self-aware AI is largely theoretical. No one can guarantee that this level of technology will ever be achieved. For now, the frontier of AI lies between limited memory and theory of mind. But it is evolving fast, and it is important to stay aware of the potential risks and benefits of this technology.
