With all due respect, are you sure you're not the one being dogmatic here?

90% of the code I write these days is Rust. It's a great tool, and the performance/safety balance, as well as general developer experience makes it well-suited to a wide variety of applications.

But in the past I've also built an ECS implementation. For that to optimize performance (and yes I did measure this) you want to do bulk memory allocations memory, pack bytes in order to minimize cache misses, and dispatch multiple threads to read and write concurrently over your memory pool. You can do all that in Rust, and people have, but it's a pain in the ass.

And for example, if I were working on a high-frequency trading application, where every millisecond of additional latency represents millions of dollars of lost revenue, I wouldn't waste my time fighting the burrow checker just so I can have a prettier program.

Rust is an amazing tool, but that doesn't mean it's the optimal tool for every job.
