In my experience most of the community in Elm is made up of people who don't really know what type classes can give you, for example, but they'll happily argue that it's too advanced or not needed. Most of that comes from parroting the popular in-community opinion instead of informing themselves.

This kind of inbred opinion is not unique to Elm: you can find it in Elixir, Clojure and pretty much every other community that relies too much on the benevolent dictator or the prominent founder/inventor paradigm.

[...] I also find it interesting that a lot of these languages that rely on this paradigm have leaders that constantly complain that it's hard to run this kind of community. The reason it's so hard is because they've made themselves a benevolent dictator and they keep that status quo because presumably they like that they can sort of control opinion in the community that way as well.

It's like when you don't know someone they are more interesting, they can be anyone you like them to be.
