COBOL is not dead, but it's difficult to get access to, because there is almost no open-source tooling around it for Linux. We (OCamlPro) have created a project, called SuperBOL, to create an open-source environment around the GnuCOBOL open-source compiler (that is now very mature and used by companies). We have already released the VScode extension with an LSP for COBOL to get a modern IDE, and we are working on other tools, mostly depending on our customers.
