Okay so I’m wondering, if you’re not in the Golang universe yet, what language is better to start with learning?

I'm curious as well. Are there alternatives to Go in some fields completely dominated by it? (like Kubernetes controllers/operators)

Depends on what you want to do.

Go's channels are probably awesome, if you need parallel computing.

If you want to build in k8s land, you can't avoid Go.

But besides that?

Maybe, use Gleam or Elixir.
