Ask HN: What do you dislike about Erlang?

My main interest these days is writing non-blocking GUIs. I don't want to see a "spinning beach ball" or "no results found" or similar things ever.

In theory Erlang has the best non-blocking support of any language, but I see a lot of risk in developing prototypes to get to the point where I know it was a good decision.

I don't see Elixir as moving the needle so far as what is conceptually tricky about Erlang.

No one uses it. The average programmer writes Javascript/Java/Python code. Erlang is a great functional language, and I've actually seen it used in the real world, but it goes above the heads of most programmers.

It’s dynamically-typed and it doesn’t have real arrays. It can sometimes be frustratingly slow to do things that imperative languages do easily, but that’s the price of entry for functional languages. Luckily you can drop down into Rust or C if you need high performance.

Otherwise, it’s a great language. I’m consistently happy with the decisions that the Erlang and Elixir core teams make, and it’s my go-to language for web development.

High learning curve. First two weeks might fry your brain.

Language is perfect for what was created: matching pathologicaly ordered number arrays (phone numbers); but needs some way to get people onboard fast.
