To some extent, that’s not the point. You don’t need to learn all of CS in one tool.

That said, I think you can learn good fundamentals of SWE with tools like Snap!. You can still learn testing, design patterns, working with APIs, modularity etc.

No it’s not a distributed system, and perhaps the biggest pain point is collaboration is tricky. But still you can learn a ton of cool things without going that far into CS. :)
