I love Elixir but you cannot compile it into a single binary, it is massively concurrent but single-threaded slow, and deployment is still nontrivial.

And lists are slower than arrays, even if they provide functional guarantees (everything is a tradeoff…)

That said, pretty much everything else about it is amazing though IMHO and it has unique features you won’t find almost anywhere else

That doesn’t exist yet. Also Elixir is in no way a replacement for Go.

It can’t match it for performance. There’s no mutable array, almost everything is a linked list, and message passing is the only way to share data.

I primarily use Elixir in my day job, but I just had to write high performance tool for data migration and I used Go for that.

My vote is for Elixir as well, but it's not a competitor for multiple important reasons. There are some languages in that niche, although too small and immature, like Crystal, Nim. Still waiting for something better.

P.S. Swift, anyone?

yeah, if the requirement is "makes it pretty straightforward to write reliable, highly concurrent services that don't rely on heavy multithreading", Elixir is a perfect match.

And even without types (which are coming and are looking good), Elixir's pattern matching is a thousands times better than the horror of Go error handling

This one i can get behind.
