They progress the language by adding syntactic sugar. Many Ruby programmers aren't waiting around for Ruby to suddenly become fast. If that happened it'd be great, but most code I write isn't performance critical, so it's okay if they just give me a feature where i can write `user&.name` instead of `user && user.name`
