The changes to C++ are too little, too late. These changes should have been made years ago, and C++ has lost momentum and credibility. Is anyone comparing Python to c++? nope, only the other way around.
Are you suggesting C++ lacks available libraries? Because for all of its faults, lack of libraries is not one I've run into.
Many desktop and server applications are still written in C or C++, including the Web browser I'm writing this on. Reports of their deaths are exaggerations.
Unfortunately, many programming tutorials are written by an intermediate for a beginner. This means they can only take you so far. Thankfully, C++ is so old that there are quite a few superb books on both the language (and it's many pitfalls) and applying the strengths to build large scale, maintainable programs.
C++ does not need the credibility. Hey, in what language is your Python compiler written in C/C++. When performance is the criteria C++ will shine. The world runs on C/C++, this comes from a C# developer.
