C++ is several different languages in one compiler.

You can use it as a stricter C, as a C with some syntactic support of ADTs, as C++98-style OO, or as a C++17 style meta-programming system.  And I’ve probably missed a few.

The resulting complexity requires a lot of discipline to use successfully, especially in a large team.

Java competes pretty successfully with the C++98-style OO subset.  C11 now competes with the stricter C subset.

The C++17 feature set competes with ... LISP, maybe?  It’s a pretty clear winner for some  application areas.
