Definition of Artificial Intelligence

Artificial Intelligence is defined as the ability of machines to perform tasks that require human intelligence, such as learning, reasoning, and perception. AI machines or systems are capable of processing large amounts of data, identifying patterns, making decisions based on those patterns and performing machine learning. There are several types of AI, each with its own capabilities and limitations.

"Artificial intelligence is the new electricity. Just as electricity transformed almost everything we do 100 years ago, today AI has the potential to profoundly transform almost everything we do in the next 100 years" - Andrew Ng, computer scientist and entrepreneur.

Brief History of Artificial Intelligence

The history of AI dates back to the 1950s, when researchers began to explore the idea of creating machines that could perform tasks that previously could only be done by human beings. Arthur Samuel developed one of the earliest computer programs related to AI in 1959, which was designed for playing checkers, not chess. However, the chess-playing computer program named Deep Blue was developed much later by IBM, and in 1997 it made history by defeating the world champion Garry Kasparov. In the following decades, researchers continued to develop and improve AI systems, creating more advanced algorithms and applying them to a wide range of fields, such as robotics, computer vision, and natural language processing.

The Importance of AI in the Modern World

Today, it's commonly agreed upon that AI has become an integral part of our day-to-day lives and is used in a wide range of applications and businesses. There are many types of artificial intelligence systems.

AI is used in healthcare to help diagnose diseases and perform complex surgeries more accurately. In financial firms, the use of AI is prominent in mathematics, fraud detection and improving risk management. In manufacturing, AI-equipped robots can automate production and improve efficiency. In the car industry, AI is used for self-driving cars. They can even be used by a child to complete tasks.

In addition, AI has enabled significant advances in areas such as scientific research, there are other applications of intelligence, such as space exploration and environmental protection. As the technology continues to evolve, it's likely that humans will see even more applications of AI in the future, thanks to which it could have a significant impact on society and the economy.

Levels of Artificial Intelligence: What are the stages of Artificial Intelligence?

There are different ways to categorize the stages of AI, but one common way is:

  1. Artificial Narrow Intelligence (ANI): ANI refers to systems that are designed to perform a specific task or a set of tasks with a high level of accuracy, but do not have the ability to generalize beyond the specific task or adapt to new situations. Examples of ANI include image recognition systems, language translation systems, and game-playing algorithms.

  2. Artificial General Intelligence (AGI): AGI refers to systems that have the ability to perform any intellectual task that a human can. AGI systems are not limited to specific tasks or domains and can learn and adapt to new situations. AGI is often considered the ultimate goal of AI research.

  3. Artificial Super Intelligence (ASI): ASI refers to systems that surpass human intelligence in all areas, including creativity, problem-solving, and social intelligence. ASI is often portrayed as a hypothetical stage of AI that may be reached in the future, but there is currently no consensus among AI researchers about whether it is achievable or what its implications would be.

It is worth noting that some researchers propose additional stages or subdivisions within these categories, and there is ongoing debate about the definitions and boundaries of these stages.

Understanding the types of Artificial Intelligence: How many types of AI are there?

As AI technology has advanced, researchers have developed different types of AI systems that can be classified into different categories based on their capabilities and limitations. Here are some of the most common types of AI and what they do.

Different types of AI: Reactive Machines

What are Reactive Machines?

Reactive machines (also known as reactive AI) are Artificial Intelligence systems that can make decisions based on specific inputs without the need to store prior information. In other words, these systems have no memory or internal state, so they can only respond to inputs they receive in real time, like voice assistants.

Examples of Reactive Machines

A common example of a reactive machine is a thermostat. The thermostat is activated when the temperature in a room drops below a certain threshold and turns off when the temperature returns to normal. Another example is a car's cruise control, which automatically adjusts the vehicle's speed based on traffic conditions.

Different types of AI: Limited Memory AI

Limited Memory AI Understanding

Limited Memory AI is a type of AI that can remember things in the short term, but cannot store it permanently. These systems are useful for performing specific tasks, such as language translation or speech recognition.

Examples of Limited Memory AI Systems

A common example of limited memory AI is the virtual assistant on a smartphone. The assistant can remember your name and other personal information, such as email, but cannot remember previous conversations unless specifically instructed to do so. Another example is speech recognition software, which can remember the pronunciation of specific words, but cannot remember previous conversations.

Different types of AI: AI Theory of Mind

Definition of AI Theory of Mind

Artificial Intelligence Theory of Mind refers to the ability of an AI system to understand the emotions, intentions, and beliefs of other people. They use mental models to predict the behavior of others and adjust their own behavior accordingly.

Examples of Artificial Intelligence and AI Systems Theory of Mind

A theory of mind AI system would be emotion recognition software. This software can analyze facial expressions and speech tones to determine a person's emotional state and adjust its own behavior accordingly. Of particular note is the movie recommendation system, which uses mental models to predict which movies a user will like based on their previous movie choices.

Different types of AI: Self-Aware AI

The Concept of Self-Aware AI

Self-Aware Artificial Intelligence is a type of system that has the ability to be aware of its own existence and its environment. As an application, they can perform complex jobs or functions and make decisions based on their own experience as well as previous stored information.

Although there are currently no self-aware AIs on the market, researchers are working on developing this breakthrough. One AI system approaching self-awareness is the humanoid robot Sophia, created by Hanson Robotics, which can ask questions and respond autonomously in real time.

Real World Applications of Artificial Intelligence

Artificial intelligence (AI or AI) has become a fundamental area of development in our daily lives, and is being used in many areas, from robotics to natural language processing to gaming.


Robotics is one of the fields that is increasingly benefiting from AI. Robots can be programmed to perform repetitive tasks, but they can also be programmed to make autonomous decisions and actions in changing environments.

Possibilities in Robotics

The possibilities in robotics are endless, from childlike robots that can perform simple jobs around the home, to advanced intelligences that can perform complex tasks in environments dangerous to human individuals, such as space exploration.

The Role of AI in Robotics

The role of Artificial Intelligence in robotics is crucial, as AI can improve the perception and decision-making of robots. An example is the humanoid robot Pepper, developed by Softbank Robotics, which can recognize emotions and communicate with humans in a natural way.

Natural Language Processing

Introduction to Natural Language Processing

The term natural language processing (NLP) or natural language processing is a branch of artificial intelligence that focuses on the interaction between humans and machine computers using natural language. The introduction of the NLP element is something that has improved communication and interaction between humans and computers. NLP can process large amounts of natural language information and understand the intent behind the words, which has significantly improved the ability of computers to communicate with humans effectively.

How AI Improves Natural Language Processing

Artificial Intelligence improves NLP by enabling people and computers to learn from experience and improve their ability to recognize patterns and respond more effectively to user requests.


The use of Artificial Intelligence in gaming

The use of Artificial Intelligence in gaming has led to almost science fiction-like gaming experiences that are increasingly interactive and personalized. AI can tailor the game to each player's experience and skill, providing a personalized challenge.

The Impact of Artificial Intelligence on Gaming Experiences

The impact of AI on gaming experiences can also be seen in AI used on non-playable characters (NPCs). NPCs can be programmed to make autonomous decisions and respond to players in a more natural way, which creates a more immersive and realistic gaming experience.

Limitations and Challenges of Artificial Intelligence

Data Dependency

Artificial Intelligence is highly dependent on the availability and quality of internet data used to train machine learning models. If the data is incomplete, inaccurate, or biased, the AI results will be as well. In addition, data privacy can also be an issue, as a large amount of data is needed to train AI models, which may require the collection and storage of large amounts of personal information.

However, data quality issues are not only a technical problem, but can also have ethical and social implications. Biased data can reinforce stereotypes or prejudices and thus perpetuate discrimination. Therefore, it is important to address not only the quality of the data, but also the social and ethical context in which it is collected and used.

"Artificial intelligence is neither artificial nor intelligent. It is simply software. All the 'decisions' it makes are programmed by humans, and reflect the biases and assumptions of its creators" - Margaret Mitchell, expert in artificial intelligence ethics.

The Problem of Creativity

Another major challenge in Artificial Intelligence is the ability of AI to be creative. The field of human creativity is a complex process involving the ability to generate new ideas and solutions, and AI currently cannot replicate these processes or functions in effective ways. Although significant advances have been made in areas such as art and AI-generated music, creativity remains one of the most difficult human abilities to mimic. However, some researchers believe that AI may be able to mimic human creativity in the not-too-distant future. AIs using deep learning algorithms have proven capable of producing original and stunning images and music.

Potential Job Displacement

AI also presents a significant challenge to the job market. As technology continues to improve, other jobs that were once performed by humans may be replaced, especially in areas that require repetitive or cognitive skills. This could have a significant impact on the economy and society as a whole, as it could lead to job loss and economic inequality. However, it is also important to keep in mind that AI can also create new jobs for businesses and economic opportunities.

AI presents a number of challenges and limitations that need to be addressed carefully and strategically. As the technology continues to improve, it is important to consider not only the technical aspects of AI, but also the broader ethical, social, and economic implications. In doing so, we can ensure that AI is developed responsibly and for the benefit of society as a whole.

The possibilities of artificial intelligence (AI) are endless, and it is clear that it can make our lives easier and better. Moreover, it is expected to bring considerable prosperity.


Throughout this article we explored the different types of artificial intelligence, from reactive machines to AI theory of mind and self-aware AI. We also discussed the real-world applications of AI, from robotics to natural language processing and gaming, as well as the limitations and challenges of AI.

Summary: The different types of artificial intelligence

Each type of artificial intelligence has its own characteristics and limitations. Reactive machines are able to make decisions based on the data they receive in real time, while limited memory AI can remember certain things but cannot learn from their experience. AI theory of mind is able to understand the intentions and emotions of others, and self-aware AI is able to make decisions based on its own experience while being aware of its existence.

Imagining the Future of AI

The future of AI is exciting and full of possibilities. AI is increasingly being used in a wide range of industries and fields, from medicine to agriculture to education. Advances in AI are also enabling the creation of more advanced and autonomous robots, which could have a huge impact on society and the way we work and live.

Final Thoughts on Artificial Intelligence

However, it is also important to keep in mind the limitations and challenges of AI. The reliance on data and the need for large amounts of information can limit the scope of AI. In addition, the issue of creativity and potential job substitution are important challenges that must be addressed as AI continues to evolve. Ultimately, it is important to continue to advance AI research and development, but also to be aware of its limitations and ensure that its use is ethical and responsible.
