If you are wondering why people seem a bit offended by your comment, it's because calling something vapourware has an implication almost of dishonesty or a con.

Crystal is real software that you can use today and build yourself and modify. It's doesn't make sense to accuse it of being vapourware.

I've always taken "vaporware" to refer to abandoned software.

This makes sense if you mean abandoned before release.

Ha! It's even made it into Merriam-Webster's!

I'd hardly call a language with a fully-functioning compiler, a fairly complete standard library, which is being used in production in multiple (albeit small) companies as vaporware.

Crystal, I don't know, but how is Elixir vapor?

I honestly don't know a ton about it, but I see it mentioned in the same cool kid crowd of "rubyists" a lot.

Then I guess you just have a weird concept of what 'vapor' is in this context.

I believe you were thinking about so-called "hipster languages".

The language works. It has a full toolchain. It has Erlang interoperability.

If the entire Elixir project and team disappeared tomorrow, I could still write the same software and deploy it to the same (decades-old) BEAM VM.

You should swing by https://elixirforum.com/ and see what's going on in the community. There are a lot of ELixir users who come from Java, OCaml, Haskell, Ruby, C#/F#, and further afield. It's a great language with a really sold niche in building systems with low latency, high availability, and good parallel data processing.
