Using python for a purpose like this is extremely strange -- it clearly is just technology debt they've been carrying around from a silly decision over a decade ago -- so someone mentioned a contemporary, more acceptable alternative. I don't really see why this threatens some people, much less the incredibly stupid "religious" nonsense.

Rust has lots of inertia behind it, a fantastic core library, fantastic concurrency and scalability and excellent LLM support. If someone were greenfield building a service like this today, instead of being bound by poor decisions in the past, had infinite knowledge of every toolset and language and option, there is a very good chance they would settle on Rust. They might not, but it's definitely a finalist. So not remotely surprising someone would mention it.

That this caused someone to flip out is hilarious though.
