I've looked into Elixir a bit, I'd probably be into it or Rust if Crystal didn't exist, more so than Go. Something about languages that run in a VM turns me off tho, reminds me of Java too much I guess. I've never heard of Gleam, that makes two languages I've learned of due to Lemmy in like 3 weeks!
I wouldn't dismiss VM languages outright. I'm also not a fan of the Java VM but the two VMs are very much very different. Also Erlang (and it's VM) were built for telecommunication, and the problems they tried to solve 30 years ago with it are very similar to modern backend engineering problems.
Erlang is in large parts also what allowed WhatsApp to scale to it's userbase with only 30 engineers.
