What is Artificial Intelligence (AI)? – Introduction and History
🟢 1. What is Artificial Intelligence?
Artificial Intelligence (AI) refers to the implementation of human-like thinking, learning, decision-making, and problem-solving abilities on computers and machines. It enables machines to perform tasks typically requiring human intelligence such as understanding, reasoning, and decision-making.
•We use AI-powered tools every day, such as:
•Google Assistant
•Siri
•ChatGPT
•Recommendation systems like those on YouTube and Netflix
•Smart TVs and mobile apps
All these technologies operate based on AI.
🟢 2. Differences Between Human Intelligence and AI
🟢 3. Types of AI
1. Narrow AI (Weak AI) :
AI developed to perform a specific task only.
Examples: Siri, ChatGPT, Google Translate
2. General AI (AGI) :
AI that functions with intelligence similar to the human brain.
This is still a scientific concept under development.
3. Super AI :
AI with intelligence surpassing human intelligence.
This is a future projection still in the theoretical stage.
🏛️ II. History of Artificial Intelligence
🟢 1. The Beginning – 1950s
The concept of AI is not entirely new. It became scientifically recognized through the work of Alan Turing, who, in his 1950 paper "Computing Machinery and Intelligence", posed the question:
"Can machines think like humans?"
🟢 2. Alan Turing and the Turing Test
Alan Turing proposed the Turing Test, in which a machine is said to exhibit intelligence if a human conversing with it cannot distinguish whether the conversation partner is a machine or a human. If indistinguishable, the machine is considered to have AI.
🟢 3. 1956 – The Dartmouth Conference
In 1956, at Dartmouth College in the United States, the term “Artificial Intelligence” was first used.
This conference brought together experts like Marvin Minsky, John McCarthy, Allen Newell, and others who deeply discussed and explored this new field.
🟢 4. 1970–1990: The AI Winter Era
During this period:
Many research projects failed.
Due to lack of funding and unmet expectations, the term “AI Winter” was coined to describe the decline in interest and investment in AI.
🟢 5. The New Renaissance – Post-2000
With advances in computing power, cloud storage, and the explosion of data, AI gained a second life.
Tech giants like Google, Facebook, Amazon, and Microsoft made massive investments in AI.
Products like ChatGPT, Tesla’s autonomous features, and Siri became widely popular and accessible to the public.
