I have three specific questions about this:
- Can you make your program executable directly from the command line, by using a shebang and building an executable binary?
- What about the startup time?
- Do you need a lot of "boilerplate", or can you put everything in a single file?

You can also compile Elixir and Erlang to native code if you want it to run computational stuff faster...

@compile [:native, {:hipe, [:verbose, :o3]}]
:-o

I switched from Ruby to Scala, and I have had an absolute blast. Elixir is sort of chained to BEAM, which doesn't appear to have as bright a future as the JVM or LLVM does, so Scala seemed like a safer bet. Reading about Elixir is cool sometimes, but then I look at Dotty, and I feel confident that I made the correct choice. I've also been keeping an eye on Crystal (statically typed Ruby-esque language, LLVM), but the…
When you say BEAMs future is not as bright, what indicators are pointing you in that direction?

Apples and oranges. LLVM is not a virtual machine, it's a compiler development infrastructure. But JVM vs. BEAM is a sensible VM comparison.
Note the lack of technical claims that one is superior to the other, thanks for pigeonholing what I was getting at.

Or JS with Scala.js Or literally anything with Scala Native, which is being sponsored and supported by EPFL directly. So yeah, no.
I saw about 5-6 products which use Scala.js and I haven't heard of any of them before. Who else uses that? Seems rather obscure. Is Scala Native used widely? They just finished implementing java.lang.String 20 days ago or so. At least Erlang on Xen has been serving web pages for a few years now: http://erlangonxen.org But most usage of Scala is on JVM still, wouldn't you agree? We are not talking CPython/Jython/PyPy/…
Scala Native is not very far along compared to Scala.js, but it is actively being improved, and is considered an official extension. Additionally, Dotty will bring huge improvements for JVM scala.
I am not super happy with JVM most days, but I'd far and away prefer to be chained to JVM than BEAM. I mean, it's not even a question at this point, considering the billions of dollars spent developing JVM and the work of the brightest minds of several generations. Joe is a cool guy and all, but Erlang is objectively a niche platform compared to JVM.

Relative to LLVM, I mean. I don't think there are any huge red flags with regards to BEAM.

Add this at the top of your module (in Elixir): @compile [:native, {:hipe, [:verbose, :o3]}] :-o
But it doesn't produce a native binary, does it?

Hi forgot about HiPE :-) But it doesn't produce a native binary, does it?
Where did I claim it did?
Is using HiPE a standard practice in the Erlang/Elixir community? What is the quantitative performance gain?

Nowhere :-) I read too fast and mistakenly assumed native code = native executable binary. Is using HiPE a standard practice in the Erlang/Elixir community? What is the quantitative performance gain?
I just discovered about HiPE as well, and I just gave it a try with a simple fibonacci module. Running fibonacci(40) went from 3.9s BEAM to 0.7s HiPE.
I know it's a silly test, but it's pretty sweet to witness such a massive difference out of the box. :)
