Yeah, i agree. I think there is a time where rewriting in a faster language is useful (just like how handcrafted assembly is still a thing), but most of the time you are very far away from the point where that is neccesary.

I also think there is an element of, "rewrite in rust" is just easy to say, where changing data structures or whatever requires analysis of the problem at hand.

It is analogues discussion to C vs Rust. Sure Rust is memory safe, but whole ecosystem I am using today is C based. Compiler, SDK, drivers, RTOS, ... Nobody sane is going to rewrite it for the sake of rewriting it into a different language.

I would disagree with that comparison. Rust really does provide an improvement in memory safety that is hard to achieve by other means. That's not to say you should always rewrite in rust, there are plenty of situations where that doesn't make sense. However its not analgous to the performance situation in my opinion.
