In the last fifteen years, I’ve worked at banks, insurance companies, and telcos on COBOL, and defence contractors and telcos with Ada.
There is always talk about replacing these huge legacy systems with something in Erlang, or Rust, or even Java (!); but some of these systems are more than fifty years old, with patches on patches, so in my opinion, replacement is going to be cumbersome and impractical.
