"Still the standard" among people who don't know that C++ is faster than C.
Fortran used to be the language for what we now call HPC. C was too slow. C++ is used now. This did not happen because Fortran got slower. Instead, C++ got faster.
The reasons are interesting. It turns out that to get faster Fortran, your compiler vendor has to code optimizations in the compiler. But in C++ you can code them in a library, and not wait on the attention of a compiler developer.
