I think you misunderstand the direction the author is coming from - Jynn is definitely not a newcomer to Rust who doesn't understand why things in Rust are the way they are
Yep - I came away from this as someone who hasn't touched Rust yet as "Yes, it's complicated, but that's for good reasons, because all of these complicated things work very well together to make writing software better ... when that doesn't happen you have things like Pythons pattern matching which is yuck".
