I do not think all this language fragmentation is a good thing. A million little obscure languages that all at the end of the day do the same thing.
Yeah, we need language research to keep devising new features and more efficient ways of programming, but this is different.
I wish the world would get behind a couple well thought out languages that cover most programming needs (functional, systems/bare metal, scripting) and stick with those.
I've seen some ridiculous and unsustainable stacks at some shops because everyone got to pick their favorite language. Then the morale of subsequent hires is in toilet because there's such a cognitive load to learn all these little crap languages.
I feel like some of these languages come about because someone needed to do some task and didn't understand or take the time to learn how to do it in an existing language. Among the latest versions of the mainstream language, there is no programming paradigm you cannot do.
And where these obscure languages REALLY fall down is tooling. Got debugger support for this? Got perftool support? No, of course you don't.
With a small number of languages, work can be put into serious tooling, and fixing compiler bugs, rather than a few devs spread thin trying to keep up with the bugs in their hobby language.
