My question is: is how one approaches writing programs in Erlang, Elixir, and Gleam fundamentally different from one another? And is the difference enough for the split in the ecosystem?

> Our recent developer survey showed that the majority of Gleam programmers ... largely were not attracted to that language.

I must admit that I find that fairly bizarre. What do you imagine the source of that lack of desire is?

For context, my favorite language is F# and ML-dialects in general, but I also like what I call "principled" dynamically typed languages like Scheme, Racket, Erlang, and Elixir.
