I know that modern Fortran is a thing but from my limited experience, it is being phased out. I work for an aeronautics company that has a lot of Fortran code: flight models, material calculations, etc... Some of it is maintained but I didn't see any new Fortran project, and most of the legacy Fortran code have been replaced by C++, Java, etc... as well as more specific tools like SCADE (which generates C code).

Same thing for ADA.
