problem is that the original COBOL programmers were expecting their stuff to be replaced within a decade, they never realized that companies would never pay to replace something if it was still (barely) functional after years of neglect – now those programs have become the backbone of their company and they’re having to shell out because it takes a special breed to learn COBOL in the day of C, C++, C#, Elixir, Nim, Crystal, JavaScript, Lua, GDScript, Dart, Swift, Kotlin, Clojure, …, …, …
Tl:dw; She's a social person and cobol is an antisocial type of job, there's nothing wrong with the cobol job industry as a whole, and it's generally an incredibly stable position to have.
