The problem with those old codebases that governments, hospitals, big businesses are struggling with is not really the language, it's the engineering practices of that time with regards to constraints of old technology. The language is not the problem - lack of comments, bad variable naming, bad structure (little or no procedures or readability), and just sheer volume of it, is.
It would be very interesting to see the old systems rewritten in a modern language, with modern engineering practices, but keeping the old UI and UX (which often is incredibly ergonomic) - so as to limit scope and not mess it all up by trying to introduce mouse navigation and windowing mess.
