We're Back!
It has been a while since I made a post here.
During this time, I explored quite a few Computer Science courses, curricula, and learning paths.
I looked at what they do well, where they fall short, and, more importantly, what I felt was missing.
And I kept coming back to one question:
What if we didn't just learn how to USE today's technology...
What if we actually understood the JOURNEY that created it?
That question led us to something new.
🚀 Welcome to “The Complete Understanding of Computer Science — From Abacus to AI”
This is not going to be another course where we rush through Python, learn a few frameworks, build a couple of projects, and immediately ask:
“How can I make money with this?”
There is absolutely nothing wrong with learning those things.
But I believe there is a much deeper path.
We are going back to the beginning.
From numbers and the Abacus...
→ Mathematical Thinking
→ Logic
→ Algorithms
→ Information
→ Computation
→ Programming
→ Data Structures
→ Computer Architecture
→ Operating Systems
→ Computer Networks
→ Databases
→ Software Engineering
→ The Internet
→ Artificial Intelligence
→ Machine Learning
→ Deep Learning
→ Generative AI
→ Intelligent Agents
→ And beyond...
But here is the important part:
We won't simply study WHAT was built.
We will try to understand WHY it had to be built.
Why did humans need algorithms?
Why weren't numbers enough?
Why did we need abstraction?
Why did programming languages emerge?
Why did operating systems become necessary?
Why did databases appear?
Why did computer networks become essential?
Why wasn't traditional programming enough?
Why did Machine Learning become necessary?
Why did neural networks return?
Why did Deep Learning change AI?
And finally...
Why have we arrived at today's era of Generative AI and increasingly capable intelligent systems?
This changes the entire way we learn.
Instead of memorizing technologies, we begin to understand the PROBLEMS that create technologies.
And I believe that is one of the most important abilities a Computer Scientist can develop.
🧠 WHY UNDERSTAND COMPUTER SCIENCE WHEN AI CAN ALREADY CODE?
This may be one of the most important questions of the AI era.
AI can write code.
AI can explain code.
AI can generate websites.
AI can build applications.
AI can implement algorithms.
AI can analyze data.
AI can help researchers explore scientific problems.
So why should we spend years understanding Computer Science?
Because USING intelligence is different from UNDERSTANDING what is being done.
If AI gives you a solution, your ability to evaluate that solution still depends on your understanding.
Is the algorithm appropriate?
Is the architecture scalable?
Is the complexity acceptable?
Is the data structure correct?
Is the model actually learning what we think it is learning?
Is the result statistically meaningful?
Is there a better way to formulate the problem?
Where does the system fail?
What assumptions are hidden inside it?
And perhaps most importantly...
Can you identify a problem that nobody has solved yet?
The tools will change.
The frameworks will change.
The programming languages will evolve.
The AI models will change.
But the underlying principles of Computer Science will continue to matter.
🔬 FROM “LEARNING TECHNOLOGY” TO “LEARNING HOW TO THINK”
There is another reason I want to build this differently.
I don't want this community to produce only developers who know how to use tools.
I want us to develop:
Problem Solvers.
Researchers.
Engineers.
Inventors.
Builders.
Thinkers.
Because when you understand fundamentals deeply, something interesting begins to happen.
You start seeing connections.
You can take an idea from Mathematics and apply it to Computing.
You can take an idea from Biology and apply it to AI.
You can understand why a particular architecture works.
You can question existing approaches.
You can design experiments.
You can reproduce research.
You can identify limitations.
You can formulate better questions.
And eventually...
You can create something that did not exist before.
That is the transition I want us to make:
Consumer → Practitioner → Researcher → Innovator
💰 BUT WHAT ABOUT MAKING MONEY?
Let's be honest.
Many people are learning AI because they want better careers, freelancing opportunities, businesses, startups, or higher salaries.
There is absolutely nothing wrong with that.
But I believe there are two very different strategies.
Strategy 1:
Learn the currently popular tool.
Use it until the market changes.
Then learn the next tool.
Then the next.
Then the next.
Strategy 2:
Understand the foundations deeply enough that when the tools change, you can learn the new tools much faster.
The second path is slower in the beginning.
But it can become incredibly powerful over time.
The World Economic Forum's Future of Jobs Report 2025 identifies analytical thinking as the top core skill among employers, while AI and Big Data, technological literacy, creative thinking, systems thinking, curiosity, and lifelong learning are among the skills expected to become increasingly important.
So yes...
AI skills matter.
But AI skills built on top of strong reasoning, mathematical, computational, and systems foundations can become much more powerful.
The goal isn't simply to become someone who can OPERATE today's AI tools.
The goal is to become someone who can:
Understand.
Build.
Evaluate.
Improve.
Research.
And eventually...
INVENT tomorrow's tools.
🧠 AND THERE IS SOMETHING EVEN BIGGER HERE...
Learning Computer Science properly isn't only about getting a job.
It changes the way you approach problems.
You begin breaking large problems into smaller problems.
You learn abstraction.
You learn to recognize patterns.
You learn to reason about constraints.
You learn to think in systems.
You learn to question assumptions.
And you learn to ask:
“What exactly is the problem?”
BEFORE asking:
“What is the solution?”
That difference is incredibly powerful.
And perhaps this is one of the biggest reasons I want to take this journey slowly.
We are NOT racing toward the finish line.
There is no shortcut here.
This will NOT be a 30-day sprint where we learn a few technologies and declare ourselves “AI Engineers.”
It may take a long time.
And that's intentional.
Because we aren't trying to merely LEARN Computer Science.
We are trying to develop a COMPUTER SCIENCE MIND.
🌍 FROM ABACUS → TO AI
Think about how extraordinary this journey really is.
Humans started with simple tools for representing and manipulating quantities.
Then came mathematical ideas.
Logic.
Mechanical computation.
Electronic computers.
Programming languages.
Algorithms.
Operating systems.
Computer Networks.
The Internet.
The Web.
Mobile Computing.
Cloud Computing.
Machine Learning.
Deep Learning.
Generative AI.
And now increasingly capable AI systems.
This isn't simply a collection of technologies.
It is a story of HUMAN PROBLEM-SOLVING.
And I want us to experience that story.
At every major step, we will ask:
❓ What problem were humans trying to solve?
❓ Why wasn't the previous solution enough?
❓ What new idea solved the problem?
❓ What limitations remained?
❓ What did those limitations eventually lead to?
That is how I hope we can develop the habit of thinking like researchers and innovators.
🤖 WELCOME TO THE ERA OF AI
And this is where our journey begins.
Not with the latest AI framework.
Not with the latest AI model.
Not with a list of prompts.
We begin with the FOUNDATIONS.
And slowly, step by step, we will travel all the way to AI.
Some of you may already be programmers.
Some may be engineers.
Some may be students.
Some may be researchers.
Some may be teachers.
And some of you may be completely new to technology.
It doesn't matter.
START FROM WHEREVER YOU ARE.
Bring your curiosity.
Bring your questions.
Bring your willingness to struggle with difficult ideas.
And most importantly...
Don't be afraid of NOT knowing.
Every great invention began with someone who didn't know the answer.
