What makes you think that Fortran is not a modern language? And when writing scientific code which involves multidimensional matrices, Fortran is most of the time more readable than C, because you can do array slicing, use elemental functions over an array (like simply doing sin(a) where a is an array).
Your whole post is just complaining about Fortran still beeing used, but you don't really explain why. The only point I can find is
> The best part: No documentation, no maintainer, and no migration plan.
which is in no way language specific.
Have you looked at modern Fortran? You have object orientation, polymophism and even parallel features like coarrays (I have to admit that I never really used them, because the gcc support is somehow incomplete).
