Thanks, I missed this at the bottom of the gist, but it was helpfully quoted in a comment:

> As one might have guessed, this is not an essay. It's a transcript of the following talk by R. Martin with some substitutions made (SmallTalk -> Haskell, Ruby -> Rust, and others). You are free to make any conclusions from this.

I think that means that this isn't a serious enough argument to be worth engaging with.
