Why is COBOL difficult?

There are a ton of reasons why COBOL is no longer used as a modern programming language. It is rigid, difficult to get started with (especially if you want to execute code on an actual mainframe) and a lot of the concepts you learn for COBOL don’t really translate to other modern programming languages.
