There was a time when C++ was one of the languages I used almost every day. It taught me how memory actually works, why performance matters, and how much control developers can have over the software they build. Like many engineers, though, my day-to-day work gradually shifted toward other languages. Python became my go-to scripting language, JavaScript found its way into side projects, and higher-level frameworks slowly replaced the need to think about pointers, manual memory management, or template metaprogramming.
A few months ago, I found myself opening a C++ project again.
What surprised me wasn't that I'd forgotten the language entirely. It was that I remembered just enough to make things frustrating. I knew what I was looking at, but I couldn't remember the details without constantly opening documentation or searching for examples. Smart pointers looked familiar, but I had to stop and remind myself when to use unique_ptr instead of shared_ptr. Modern C++ features felt recognizable, yet they weren't part of my natural workflow anymore.
That experience made me realize something I hadn't really considered before.
Relearning a programming language is a completely different problem from learning one for the first time.
The internet doesn't have a C++ problem
If you're trying to learn C++ today, you're spoiled for choice.
-There are fantastic books.
-Interactive coding platforms.
-University lectures.
-Thousands of YouTube tutorials.
-Official documentation.
-Complete learning websites.
Finding educational material is easier than it's ever been. The challenge is figuring out which parts of C++ you actually need to revisit.
That's a much harder question to answer because every developer arrives with different experience. Someone preparing for game development has different goals than someone interviewing for backend engineering roles. Likewise, someone returning to C++ after five years probably doesn't need another introduction to variables or loops.
Traditional online courses aren't really designed for those situations.
Relearning isn't the same as starting over
Most online courses follow a logical progression because that's exactly what beginners need.
-Variables become functions.
-Functions become classes.
-Classes become object-oriented programming.
Eventually you reach templates, STL containers, concurrency, memory management, and modern C++ features.
That sequence works extremely well when you're starting from zero. It becomes much less efficient when you've already spent years writing software. My problem was identifying the parts of C++ that had faded over time.
I didn't want to spend three hours reviewing concepts I'd never actually forgotten. I wanted to rebuild confidence in the parts of the language I hadn't touched in years.
That's a very different learning experience.
I realized I wasn't looking for another course
The more I searched for refresher resources, the more obvious the problem became. Every platform expected me to choose a course.
-Complete Modern C++.
-C++ for Beginners.
-Advanced C++.
-STL Masterclass.
-Object-Oriented Programming.
-Interview Preparation.
The responsibility always fell back on me to decide which curriculum was the right fit.
The irony is that making those decisions often requires knowing exactly what you've forgotten, and if you already knew that, you probably wouldn't need the course in the first place.
What I really wanted wasn't another catalog.
I wanted guidance.
That's why AI course builders caught my attention
The idea behind AI course builders feels fundamentally different from traditional online learning.
Instead of asking you to browse hundreds of existing courses, they begin by asking a much simpler question:
What are you trying to accomplish?
That might sound like a small difference, but it changes the entire learning experience.
Instead of fitting yourself into someone else's curriculum, the curriculum is generated around your goals, your experience, and the concepts you actually want to strengthen.
For someone returning to C++, that sounds much more useful than starting Lesson 1 of another beginner course.
Discovering Fenzo.ai
While exploring this idea, I came across Fenzo.ai, an AI-powered platform focused on building personalized courses rather than maintaining a fixed library of learning paths.
That immediately stood out to me because it approaches education differently. Instead of presenting dozens of predefined C++ courses and asking you to choose one, Fenzo.ai starts with your objective.
-Maybe you're preparing for technical interviews.
-Maybe you're transitioning into systems programming.
-Maybe you've written C++ before but want to refresh modern language features.
Those goals become the foundation of the learning experience rather than an afterthought. That approach feels much closer to working with a tutor than enrolling in a traditional online course.
The personalization is what interested me most
One thing I kept thinking about while exploring Fenzo.ai was how rarely online education adapts to the learner.
Most platforms personalize recommendations. Very few personalize the curriculum itself. That's an important distinction.
Imagine two developers opening the same C++ course.
One hasn't programmed before. The other has spent ten years writing Java and simply wants to refresh modern C++ before interviewing.
Should both students really begin with exactly the same lesson?
Probably not.
That's where personalized course generation starts making a lot of sense.
Instead of assuming everyone follows the same path, the learning experience can be shaped around where you already are.
Beyond static learning paths
Another thing I appreciate about the idea behind Fenzo.ai is that it moves away from the traditional "course marketplace" model. Most learning platforms continue growing by adding more courses.
Ten courses become one hundred.
One hundred become one thousand.
Eventually the biggest challenge becomes choosing which course to take. Fenzo.ai takes a different approach.
Rather than expanding the catalog indefinitely, it focuses on generating a learning experience designed around an individual learner's needs.
That feels like a meaningful shift.
Instead of asking, Which course should I buy?, the question becomes, What do I actually want to learn?
What I'd want from an AI-generated C++ course
If I were using an AI course builder to refresh C++, there are a few capabilities I'd value more than anything else.
Rather than another fixed syllabus, I'd want the platform to:
- Skip concepts I already understand.
- Spend more time on areas where my knowledge is rusty.
- Mix explanations with practical coding exercises.
- Reinforce important ideas through quizzes and review.
- Continuously adapt as my understanding improves.
Those features don't change the language itself.
They simply make the learning experience much more efficient.
AI shouldn't replace great learning resources
One thing I don't think AI course builders are trying to do is replace traditional education. Books still matter. Documentation still matters. Projects remain one of the best ways to improve as a developer. Experienced instructors continue offering explanations that AI simply can't replicate.
Where I think platforms like Fenzo.ai become interesting is everything that happens before those resources.
Instead of spending hours deciding what to study next, an AI-generated roadmap can help organize your learning so that every lesson has a clear purpose.
That guidance can remove a surprising amount of friction.
Would I choose this approach today?
If I were starting C++ from scratch, I'd probably still combine multiple learning resources.
-I'd read documentation.
-I'd build projects.
-I'd solve programming problems.
-I'd study modern C++ best practices.
But if my goal was specifically refreshing skills I'd already developed years ago, I'd seriously consider starting with an AI-generated learning path.
The biggest advantage isn't that AI somehow teaches C++ better.
It's that personalization helps eliminate unnecessary learning and focuses your time where it creates the most value.
That's ultimately what makes platforms like Fenzo.ai interesting.
They're not trying to replace programming education. They're trying to make it more personal.
Final thoughts
One of the biggest changes happening in online education isn't the arrival of more programming courses. It's the gradual shift away from one-size-fits-all learning.
Every developer has different experiences. Different goals. Different strengths. Different knowledge gaps.
Treating everyone as though they're starting from exactly the same place has always been one of the biggest limitations of online learning.
Whether AI course builders become the future of programming education remains to be seen. What platforms like Fenzo.ai demonstrate, though, is that personalization is becoming a much larger part of the conversation. If that means developers spend less time searching for the right course and more time actually writing code, that's a direction I'm excited to watch.
