History of AI
AI didn't appear in 2022 with ChatGPT — it has a 70-year history of breakthroughs and 'AI winters' (funding droughts when hype outran reality).
Introduction
AI didn't appear in 2022 with ChatGPT — it has a 70-year history of breakthroughs and 'AI winters' (funding droughts when hype outran reality). Understanding the timeline helps you separate marketing from substance.
Beginner analogy: AI's history is like rocketry — decades of research, several spectacular failures, and then suddenly SpaceX-style commercial liftoff with deep learning.
Understanding the topic
Core concepts to understand:
- 1956 — Dartmouth Conference coins the term 'Artificial Intelligence'.
- 1980s — Expert systems boom; early neural networks (backpropagation).
- 1997 — IBM Deep Blue beats Garry Kasparov at chess.
- 2012 — AlexNet wins ImageNet → Deep Learning revolution.
- 2017 — Google publishes Attention Is All You Need → Transformers.
- 2020 — GPT-3 (175B parameters) shocks the world.
- 2022 — ChatGPT launches; AI goes mainstream.
- 2023+ — Multimodal LLMs, AI agents, enterprise rollouts.

Real-world use
Each breakthrough enabled the next. Without GPUs (gaming) → no AlexNet → no deep learning → no transformers → no ChatGPT. Today's LLMs literally stand on 70 years of compounding research.
Best practices
- Read landmark papers — Attention Is All You Need (2017), GPT-3 (2020), Chinchilla (2022).
- Watch for new milestones; the field moves monthly, not yearly.
Hands-on exercise
Interview preparation — practice these questions:
- Q1. What were AI winters and why did they happen?
- Q2. Why did deep learning explode after 2012?
- Q3. What did the 2017 Transformer paper change?
