What is AI? History & Evolution
What is Artificial Intelligence?
Artificial Intelligence (AI) is the branch of computer science focused on building machines capable of performing tasks that typically require human intelligence — reasoning, learning, problem-solving, understanding language, and recognizing patterns.
A Brief History of AI
- 1950 — Alan Turing proposes the Turing Test as a measure of machine intelligence.
- 1956 — John McCarthy coins “Artificial Intelligence” at the Dartmouth Conference.
- 1960s–70s — Early programs like ELIZA and expert systems are developed.
- 1997 — IBM’s Deep Blue defeats chess world champion Garry Kasparov.
- 2012 — Deep learning breakthrough with AlexNet transforms image recognition.
- 2016 — Google DeepMind’s AlphaGo defeats the world Go champion.
- 2020s — Large Language Models like GPT and Claude bring AI into everyday life.
Why Does AI Matter Today?
AI is embedded in your smartphone, search engine, bank fraud detection, and streaming recommendations. Understanding AI is now a fundamental literacy for the modern world.
Key Takeaways
- AI makes machines simulate human-like intelligence.
- The field formally began in 1956 at the Dartmouth Conference.
- Recent advances in computing power and data have made AI practical and widespread.
