I disagree. The same was said when perl dominated before Ruby and Python came along. And Pascal, C and C++ before that. Nowadays Nim, Crystal, Rust, Go, F#, D, Zig, JavaScript, Haskell, and more are all viable options for application development.

We have more viable programming languages than ever.

I live in a moderately large urban area in france (~800k inhabitants) and for your list ("Nim, Crystal, Rust, Go, F#, D, Zig, JavaScript, Haskell") I've never seen any local job ad for any of those except JS and Go, and only saw a bit of Haskell at the university.

From a quick glance over a few dozen pages of job ads, it's mostly Java & PHP, with a bit of JS, Python and C# here and there and some C/C++ in embedded. Saw 2 node.js ads, as well as a COBOL and a Kotlin too.

So, yes, maybe they are viable. But.. used ? they're blimps in the radar next to the big ones.

In my city in the US:

+ Node.js is plentiful

+ Golang is up and coming

+ Some elixir

+ Haskell is pretty rare but it shows up as a secondary language

+ Java and php are plentiful but these tend to be large, older corporate gigs

+ Rust is rare

+ No crystal/nim/f#/zig/D that I've seen

Obviously anecdotal and your case my differ.

Sadly just because a language has a quality implementation and lots of libraries available and so is suitable for application development from an engineering point of view doesn't mean that PHBs are going to allow it to happen at the workplace, for various business reasons.
