People will do anything except actually try Elixir. :D

...I mean: pipes, immutability, transparent mega-parallelism... helloooo?

I tried F# some years ago (after I was fired from a shop that decided they will go all-in on Java and F# and dropping everything else overnight) and I was not impressed. I mean the language is really nice but the C# baggage and runtime was just a bit much. And I was not left convinced that immutability alone is worth the switch. I suppose we can call F# an FP gateway drug?

Now arguably you get a runtime and some baggage from the Erlang runtime (the BEAM VM, where Elixir also runs), but the guarantees and features you get are invaluable, and have proven themselves many times over the last literal three decades.

For me, it's Erlang. I just really like its horn clause syntax, it's so clean and readable. I know a common complaint is lack of piping (and even though you can implement it trivially, the order of arguments for some functions makes it of dubious use) but it's a small price to pay.

This was my experience with F#. Frankly, I've never been happy with my experience with CLI on Linux, and the toolchain inherits a lot of baggage from its C# heritage. Microsoft's toolchains have a very distinct workflow to them. F# has some interesting aspects to it like active patterns (something I wish was more common in the ML-family), but tbh I'm more than happy with ocaml.

I can't remember which version of Erlang was the most current when I started learning Elixir, but I do know that it was years before OTP 20, which fixed its string issues. Prior to that, Erlang didn't have very good string support for internationalization (I do a lot of Japanese language programming). Elixir, on the other hand, did. Otherwise, I may have gone with Erlang back then.

I like Erlang a lot, too. Both are great languages.
