>What would "modern" bring to a bank except even more pain & suffering? It probably depends on what "modern" means here. If updating from tons of COBOL to {Julia, Python, Rust, or some other well known language} with an update to an SQLite backend (or perhaps postgres is acceptable for very specific scenarios), that is likely a good choice due to being able to fix old cruft and add maintainability for the future. If it's a switch to some nosql database backend with everything switched to some cypher-based lang or anything that touches javascript in any way, it's probably a mistake.
