Earlier quoted context omitted.
C++ is not very canonical OOP. And by that I don’t just mean it’s multi paradigm nature, but it’s realization of OOP features. Using C++ teaches you mostly about using C++ and doesn’t really transfer across the paradigm.
I think that statement would have to be classified as inaccurate. using C++ teaches you mostly about general purpose programming and it's pretty easy to go from C++ to python to Java to bash, etc.
Learning bash became easy when I learned pipelines and the GNU coreutils.
Now I wish I could take what I'd learned from GNU coreutils and apply that to C++.
