Implementations of Lisp are no more niche than other languages with managed run-times.
Lisp has been used for even operating system development: Lisp code taking interrupts, and driving ethernet cards and disks and so on.
Which member of the Lisp family are you talking about, and what do you think is the niche?
No more niche than Java, C# .NET and Python? Right...

You can combine all of the Lisp family together and still it wouldn't scratch the popularity, demand or job positions of any of the top languages.
Look, nobody denies Lisp'like languages are being used. Just like Fortran. :)
Fortran has a niche: numeric computing in scientific areas. However, even Fortran is not your grandfather's Fortran 66 or 77 any more. I had a semester of the latter once, as part of an engineering curriculum before switching to CS.
It supposedly has OOP programming in it, and operator overloading and such.
I don't know modern Fortran, so I wouldn't want to look ignorant spreading decades-old misinformation about Fortran.
Infantile language tribalism though, have no place in engineering and is blatant ignorance when coming from a supposed adult.
