Have Haskell's ergonomics improved?

I feel your snark is unjustified. You might be putting people in two extremes: wise elders and hip kids. There's a huge amount of people in-between however.

(Also, the saying actually is: "You're going to where I am coming back from".)

Find me something like Erlang/Elixir with the speed of Rust and I won't learn another programming language ever again.

No? Then the search continues.

So far Haskell hasn't impressed. In all honesty Rust is quite hard to put in that niche as well since its `async` stuff is extremely annoying and hard to get right but I guess the tries are still ongoing. OCaml is progressing but who knows when will they get there.

Well, based on your comment, I might reevaluate Haskell. Last time I was severely put off by lack of good tooling (but I did hear cabal was improving) and a fragmented ecosystem. Maybe things have changed.
