For what it is worth - I write Fortran professionally (in some of the use cases you describe) and I doubt its usefulness.

The way I see it, Fortran exists today because of inertia, not because it still has technical superiority.

These mountains of Fortran code represent decades of investment and undocumented "features" that you could never code around during a rewrite.

And so today, new code is bolted on, with a prayer that nothing breaks, may god have mercy on your soul.
