This is the first justification of not using Rust that I actually agree with. Well written.

I recommend reading Roc's FAQ too - it's got some really great points. E.g. I'm internally screaming YESSS! to this: https://www.roc-lang.org/faq.html#curried-functions

But then it has other weird features too, like they seem to be really emphasising "friendliness" (great!) but then it has weird syntax like `\` for anonymous functions (I dunno where that dumb syntax came from by Nix also uses it and it's pretty awful). Omitting brackets and commas for function calls is also a bad decision if you care about friendliness. I have yet to find a language where that doesn't make the code harder to read and understand.
