Phase 1: The Big Picture Lesson 1 of 4

The Story of AI:
From Turing to Today

Before we write a single line of code or touch any data, you need to understand where AI came from, why it matters right now, and why you are not late to this.

How to place yourself in this story

Let us start with an honest question

When most people hear the words "Artificial Intelligence," they picture one of two things: a robot with glowing eyes trying to take over the world, or a futuristic technology so complex that only computer scientists at top universities could ever understand it.

Neither of those pictures is accurate. And that gap between what people imagine and what AI actually is, right now, is exactly where we are going to begin.

AI is not magic. It is not science fiction. It is a set of ideas that humans have been developing, failing at, picking back up, and slowly perfecting since the 1950s. Once you understand that story, everything else in this course will make much more sense.

"A computer would deserve to be called intelligent if it could deceive a human into believing it was human."

Alan Turing, 1950

It started with one question

In 1950, a British mathematician named Alan Turing published a paper that asked a question nobody had seriously asked before: can machines think?

Turing did not try to answer that question philosophically. Instead, he proposed a test. Put a human in one room and a machine in another. A judge communicates with both through text only, without knowing which is which. If the judge cannot reliably tell which is the human, the machine has passed the test.

This was the moment the field of AI was born, not with a computer, not with data, but with a question.

Worth knowing

Turing never got to see where his question led. He died in 1954 at the age of 41. The field he inspired would go on to spend the next 70 years trying to answer it, and we are still not entirely done.

Ten moments that built the world you live in

AI history is not a straight line upward. It is more like a heartbeat, periods of enormous excitement followed by disappointment, followed by a new breakthrough that restarts the whole cycle. Here are the ten moments you need to know.

1950
The Turing Test
Alan Turing publishes "Computing Machinery and Intelligence." The question of whether machines can think enters serious scientific discussion for the first time.
1956
The birth of AI as a field
A summer workshop at Dartmouth College coins the term "Artificial Intelligence." Researchers predict machines will be as smart as humans within 20 years. They were off by quite a bit.
1974
The first AI winter
Funding dries up. Computers are too slow. Data is too scarce. The early promises were not delivered. Governments and universities lose interest, and AI nearly disappears as a field.
1997
Deep Blue beats a chess world champion
IBM's Deep Blue defeats Garry Kasparov, the reigning world chess champion. It is a landmark moment, though critics point out the machine cannot do anything except play chess.
2006
Deep learning is reborn
Geoffrey Hinton and colleagues publish research that makes training deep neural networks practical. Most people in the field ignore it. A small group does not.
2012
AlexNet changes everything
A deep learning model wins an image recognition competition by such a large margin that every serious AI researcher stops and takes notice. The modern AI era begins here.
2016
AlphaGo beats the world Go champion
Google DeepMind's AlphaGo defeats Lee Sedol at Go, a game so complex that experts said machines would never crack it. The AI beats him four games to one.
2017
The transformer architecture
Google researchers publish "Attention Is All You Need," introducing the transformer. Almost every powerful AI system you use today, including ChatGPT and Claude, is built on this architecture.
2022
ChatGPT reaches 100 million users in 2 months
OpenAI releases ChatGPT to the public. It becomes the fastest-growing consumer application in history. AI stops being a specialist topic and becomes everyone's conversation.
Now
You are here
AI is being built into every industry, every job, every device. The people who understand it will shape how it develops. That is why you are taking this course.

Why did it take so long?

If the ideas behind AI are 70 years old, why did it only explode in the last decade? Three things had to come together at the same time, and for most of AI history, at least one of them was missing.

💾
Data

AI learns from examples. The more examples, the better it learns. The internet created an ocean of data that simply did not exist before the 2000s.

⚡
Computing power

Training AI models requires enormous amounts of calculation. GPUs, originally built for video games, turned out to be perfect for the job. They got cheap and powerful at just the right time.

🧠
Better algorithms

The core ideas of deep learning existed in the 1980s but did not work well in practice. Decades of refinement turned a promising idea into something that actually worked.

☁️
Cloud infrastructure

Amazon, Google and Microsoft built global computing infrastructure that made it possible to train huge models without owning a supercomputer. Overnight, AI became accessible.

Think of it this way

Imagine a recipe that has existed for 70 years but nobody could make it properly because one essential ingredient was not available in shops yet. The recipe did not change. The knowledge did not change. The ingredient finally arrived, and suddenly every restaurant in the world started serving the dish.

Why this matters for you specifically

Here is something worth sitting with. Most of the people building and deploying AI systems today are not the people who invented the underlying mathematics. They are engineers, product designers, analysts and educators who learned how to use the tools that the researchers built.

You do not need to have been there in 1956. You do not need a PhD. What you need is a clear understanding of how these tools work, where they come from, and how to apply them to real problems. That is exactly what this course will give you.

The story of AI is still being written. The next chapter will be written by people who took the time to understand it properly. You are now one of those people.

Lesson Activity · No tools needed
The AI Audit
Before our next session, we want you to start noticing AI in your everyday life. Not the dramatic sci-fi version. The real version that is already running quietly around you.
01 Pick 10 apps or services you used in the last 48 hours. Your phone, your music, your email, maps, shopping, anything.
02 For each one, ask yourself: where might AI be involved here? What decisions is the app making automatically on your behalf?
03 Write down your list and your guesses. Bring it to the live session. There are no wrong answers. The goal is to start seeing what was always there.

Click any question to reveal a thinking prompt. There are no wrong answers.

The first AI winter happened because researchers over-promised results. Can you think of a modern AI trend that might face the same problem?

Think about large language models, self-driving cars, or AI in medicine. What promises have been made publicly? What would "failure to deliver" look like, and how might that affect funding and public trust?

Why did AI progress so dramatically after 2012? Name at least two factors.

Consider: the availability of large labelled datasets, the rise of GPU computing, breakthroughs in deep learning architectures (like AlexNet), and the growth of the internet generating vast amounts of training data.

If Alan Turing came back today, which modern AI achievement do you think would surprise him most — and which would he say he predicted?

Turing proposed his "imitation game" as a test for machine intelligence. Consider whether chatbots pass that test, and what he might say about AI that plays games, generates art, or writes code.
