4. Deep Learning and Neural Networks Era (2000s)
The 2000s marked a major advancement in Artificial Intelligence (AI), especially with the advent of deep learning and neural networks. The use of self-learning algorithms, which allows machines to learn from data without special programming, is a major focus in the industry. This technology allows the system to analyze large amounts of data and find complex patterns that are difficult to achieve with legacy methods.
One of the most striking examples of self-learning algorithms is in the field of computer vision, where this technology is used for facial recognition, object detection, and image analysis. For example, companies like Google and Facebook have implemented facial recognition technology on their platforms, so users can automatically tag friends in photos. Additionally, in the automotive industry, self-learning technology is used to develop autonomous vehicles that can understand and navigate the environment safely.
In the field of natural language processing, deep learning has also brought significant progress. Self-learning algorithms allow machines to better understand the context and nuances of human language, which helps to improve the capabilities of virtual assistants such as Siri and Alexa. With deep learning techniques, this system can process voice commands and provide more relevant and accurate responses.

1. Narrow AI (Weak AI)
Narrow AI, also referred to as Weak AI, is a type of artificial intelligence created to complete specific tasks within a limited scope. In contrast to Artificial General Intelligence (AGI), which seeks to mimic the ability of human thinking as a whole, Narrow AI is only capable of handling specific cognitive skills.
Examples of Narrow AI are virtual assistants such as Siri and Alexa, which can understand and respond to voice commands to perform various tasks such as setting reminders or answering questions. In addition, facial recognition software also falls under the category of Narrow AI, where the system can recognize the faces of people in images but cannot perform other tasks outside of those functions.
The advantage of Narrow AI lies in its ability to complete tasks very efficiently and accurately, often better than humans in certain situations. For example, facial recognition systems can process and analyze images quickly and accurately, making them an important tool in the field of security. Virtual assistants such as Siri and Alexa also provide convenience for users with quick access to information and services.
However, the main drawback of Narrow AI is its inability to adapt outside of predetermined tasks. For example, while Siri can answer questions, it can’t perform in-depth analysis or make complex decisions outside of the virtual assistant’s function. This shortcoming suggests that Narrow AI does not have a contextual understanding or the ability to learn independently beyond pre-programmed data.
2. General AI (Strong AI)
General AI, otherwise known as Strong AI and Artificial General Intelligence (AGI), is a concept in which machines can think and learn like humans. This means that AI can not only complete certain tasks, but it can also understand and apply knowledge in a variety of situations. Achieving AGI is a big challenge because it requires algorithms that can mimic the way humans think holistically, including the ability to adapt, innovate, and understand emotions.
One of the main challenges in developing AGI is the complexity of the human brain. Our brains have about a trillion neurons connected in an intricate network, allowing for highly efficient information processing. Creating a computer system that can replicate these capabilities is still a major technical challenge. In addition, there are also ethical and social issues to think about, such as the impact of AGI on human jobs and the risks if machines become smarter than humans.
In addition, there is a philosophical challenge as to what “human” intelligence means. For example, do machines that can perform cognitive tasks like humans really “think” or simply mimic human behavior? This question leads to a discussion about subjective consciousness and experience.
The Turing Test, introduced by Alan Turing in 1950, is a way to determine whether a machine can exhibit intelligent behavior that is indistinguishable from humans. In this test, an evaluator interacts with machines and humans without knowing who is which. If the evaluator cannot distinguish between the two based on the response, then the machine is considered to have passed the Turing Test.
Today, while some AI systems have demonstrated exceptional abilities in answering questions and interacting with users (such as advanced chatbots), none have consistently met the criteria of the Turing Test. Although advances in natural language processing have made interactions more natural, challenges in understanding the emotional context and nuances of language still exist.
