COBOL is not a "cool" language, but mainframes have been around long enough to be "retro cool" now, and most run Linux at least as an optional OS under some virtualization (IBM Z).
As a doctoral candidate in the noughties, I purchased a book about FORTRAN due to its "retro-coolness" and read it, and eventually took on a short university gig to earn the money that the book cost back, tutoring architects/engineers in FORTRAN 95 for a bit, which was fun; to date, I could not bring myself to do the same with COBOL, though, or not yet.
Because it is so verbose, if I had to use it I would probably write in another language and transpile to it.
