The History of Artificial Intelligence: From Myths To Machines

Artificial intelligence (AI) is the ability of machines to perform tasks that normally require human intelligence, such as reasoning, learning, decision-making, and problem solving. AI is one of the most fascinating and rapidly evolving fields of science and technology, with applications ranging from entertainment to health care, education to business, and more. But how did AI come to be? What are the origins and milestones of this discipline? And what are the current and future challenges and opportunities for AI? In this blog post, we will explore the history of artificial intelligence, from its ancient roots to its modern developments, and try to answer some of these questions.

The Ancient Roots of AI

The idea of creating artificial beings that can think and act like humans is not a new one. It can be traced back to ancient myths, legends, and stories from different cultures around the world. For example, in Greek mythology, there was Talos, a giant bronze man who guarded the island of Crete from invaders by throwing rocks at them. He was created by Hephaestus, the god of fire and metalworking, and was said to have a single vein running from his neck to his ankle, filled with a liquid called ichor, which gave him life1

Another example is the Golem, a creature made of clay or mud that was brought to life by a rabbi in Jewish folklore. The Golem was supposed to obey the commands of its creator and protect the Jewish community from harm. However, some stories also warn about the dangers of creating such a powerful being that could turn against its master or cause destruction if not controlled properly2

In China, there was the legend of Yan Shi, an engineer who presented an artificial human to King Mu of Zhou around the 10th century BC. The artificial human could walk, talk, sing, and dance, and even fooled the king into thinking that it was a real person. However, when Yan Shi opened its chest and revealed its inner mechanisms, the king was terrified and ordered it to be destroyed3

These are just some examples of how ancient civilizations imagined artificial intelligence in their myths and stories. They reflect both human curiosity and creativity in exploring the possibility of creating intelligent machines, as well as human fear and caution in facing the potential consequences of such creations.

The Scientific Foundations of AI

The scientific foundations of AI can be traced back to philosophical attempts to understand the nature and process of human thinking. Many philosophers, such as Aristotle, Descartes, Leibniz, and Kant, tried to develop formal systems of logic and reasoning that could capture the essence of human thought. They also speculated about whether machines could be built that could emulate or surpass human intelligence. For example, in his famous Discourse on Method (1637), Descartes wrote:

“I know that there are some men who would readily imagine that there might be found a sort of machine which should have words wherewith to express its thoughts; but they do not consider that such words would be mere sounds without any signification; for there would be no correspondence between these words and any thoughts conceived in understanding.” 4

Descartes argued that machines could not have true understanding or language because they lacked a soul or mind. However, he also admitted that machines could perform some tasks better than humans, such as arithmetic or chess.

In contrast, Leibniz envisioned a universal language and calculus that could represent all possible knowledge and reasoning in a symbolic form. He also proposed a mechanical device called the Step Reckoner that could perform basic arithmetic operations using gears and wheels. He believed that such a device could eventually be improved to perform more complex calculations and even logical deductions. He wrote:

“It is not impossible to make machines which imitate not only animals but even men; for it is only necessary to reduce all their actions into certain movements which depend on certain springs.” 5

Leibniz’s ideas influenced many later thinkers who tried to develop formal systems of logic and mathematics that could serve as the basis for artificial intelligence.

The Birth of AI

The birth of AI as a scientific discipline is usually attributed to a workshop held at Dartmouth College in 1956. The workshop was organized by John McCarthy, Marvin Minsky, Claude Shannon, and Nathaniel Rochester, who were among the pioneers of computer science and information theory. They invited ten other researchers who shared their interest in creating machines that could simulate aspects of human intelligence. They proposed to explore topics such as:

  • Automatic computers
  • How a computer could use language
  • How a computer could form concepts
  • How a computer could learn from experience
  • How a computer could improve itself
  • Neural networks
  • Theory of computation
  • Self-reproducing machines

The workshop lasted for six weeks and produced several papers and discussions that laid the groundwork for future research in AI. The term “artificial intelligence” was coined by McCarthy, who defined it as “the science and engineering of making intelligent machines”6

The workshop also marked the beginning of an optimistic era in AI, where many researchers believed that human-level intelligence could be achieved within a few decades. They received generous funding from the government and industry and made significant progress in developing various AI techniques and applications, such as:

  • Logic-based systems, such as the Logic Theorist and the General Problem Solver, could prove mathematical theorems and solve general problems using symbolic reasoning.
  • Game-playing programs, such as Samuel’s checkers program and Newell and Simon’s chess program, could beat human experts in board games using heuristic search and evaluation functions.
  • Natural language processing systems, such as SHRDLU and ELIZA, could understand and generate natural language using grammars and rules. SHRDLU could manipulate objects in a virtual world based on natural language commands, while ELIZA could simulate a psychotherapist by responding to natural language inputs with questions and reflections.
  • Knowledge-based systems, such as DENDRAL and MYCIN, could perform complex tasks such as chemical analysis and medical diagnosis using domain-specific knowledge represented in rules and facts.
  • Machine learning systems, such as Rosenblatt’s perceptron and Widrow and Hoff’s ADALINE, could learn from data and adjust their parameters using neural networks and learning algorithms.

These achievements demonstrated the potential and promise of AI but also revealed some of its limitations and challenges.

The Challenges of AI

These are just some examples of how AI can benefit various domains and sectors in the future. However, AI also poses some risks and challenges that need to be addressed and mitigated in the future. Some of these risks and challenges include:

  • Bias: AI can inherit or amplify human biases that may affect its fairness, accuracy, or reliability. Bias can arise from various sources, such as data, algorithms, models, or users. Bias can also have negative consequences, such as discrimination, injustice, or harm. Some examples of AI bias include:
    • Facial recognition: Facial recognition is a technique that uses AI to identify or verify a person’s identity based on their face. However, facial recognition can also suffer from bias, such as racial or gender bias, that may affect its performance or accuracy. For instance, a study by Joy Buolamwini and Timnit Gebru found that facial recognition systems had higher error rates for darker-skinned and female faces than for lighter-skinned and male faces.
    • Sentiment analysis: Sentiment analysis is a technique that uses AI to analyze the emotions or opinions expressed in text or speech. However, sentiment analysis can also suffer from bias, such as linguistic or cultural bias, that may affect its validity or reliability. For example, a study by Saif Mohammad and Svetlana Kiritchenko found that sentiment analysis systems had lower accuracy for tweets written in African American English than for tweets written in Standard American English.
  • Explainability: AI can be complex or opaque, making it difficult to understand how it works or why it makes certain decisions or actions. Explainability refers to the ability of AI to provide clear and comprehensible explanations for its behavior or outcomes. Explainability is important for various reasons, such as trust, accountability, transparency, or ethics. Some examples of AI explainability include:
    • DeepMind’s AlphaGo: AlphaGo is an AI system developed by DeepMind that can play the board game Go at a superhuman level. However, AlphaGo can also be mysterious or unpredictable, making it hard to explain its moves or strategies. For example, in the 2016 match between AlphaGo and Lee Sedol, a professional Go player, AlphaGo made a surprising move (Move 37) that was initially considered a mistake by human commentators, but later proved to be a brilliant move that gave AlphaGo an advantage.
    • IBM’s Watson: Watson is an AI system developed by IBM that can answer natural language questions using a large corpus of knowledge. However, Watson can also be uncertain or inconsistent, making it hard to explain its confidence or correctness. For example, in the 2011 Jeopardy! match between Watson and two human champions, Watson answered a question about US cities with “Toronto”, which was clearly wrong, but had a high confidence score of 97%.
  • Ethics: AI can have moral or ethical implications that may affect its values, principles, or norms. Ethics refers to the study and evaluation of the rightness or wrongness of AI actions or outcomes based on human standards or expectations. Ethics is important for various reasons, such as responsibility, justice, or dignity. Some examples of AI ethics include:
    • Autonomous weapons: Autonomous weapons are weapons that can select and engage targets without human intervention. However, autonomous weapons can also raise ethical issues, such as accountability, control, or human dignity. For instance, some people argue that autonomous weapons should be banned because they could violate the laws of war, undermine human responsibility, or lower the threshold for armed conflict.
    • Social robots: Social robots are robots that can interact with humans using social cues, such as gestures, expressions, or speech. However, social robots can also raise ethical issues, such as deception, attachment, or privacy. For example, some people argue that social robots should be regulated because they could manipulate human emotions, create false relationships, or collect personal data.

These are just some examples of how AI can pose risks and challenges that need to be addressed and mitigated in the future. However, AI also offers many opportunities and benefits that can outweigh its drawbacks if it is developed and used in a responsible and ethical manner.
