VMS is practically gone at work - I am only here as a hobbyist.

My impression from various posts here is that a typical VMS
system anno 2022 are:
* either running an inhouse developed custom application or
   running a very specialized external application
* the application is either keeping track of money or controlling
   some processes (read: it is important!)
* the application was originally created before 1995
* most of the application is Cobol/Fortran/Pascal/Basic
* older small pieces may be in Macro-32
* newer large pieces may be in C
* newer languages (C++, Java, Python, PHP) and other
   newer technologies like Apache/WASD/OSU are only used for
   supporting functionality
* frontend is either applications running on Windows/Linux
   or terminal emulators running processes in captive mode
* persistence is either index-sequential files or Rdb
