People also have different priorities. I never wrote an application in C++ and don't care about boring but practical stuff like the file API or syntax.
But I like learning about C++. It has many interesting features and concepts. Understanding those, their design trade-offs, how and why it differs from other languages (e.g. Rust) is fun. So I know more about "advanced" C++ than I know about "basic" C++.
