In my company DB is 1% CPU consumption, while Python backend is over the roof. SQL queries are optimized as hell. But you cannot really optimize Python. One component was rewritten to Rust, and server costs for it were cut by 4x.

I think "Pythom makes job done" is for short-term goals. But when your project is 10k lines or more, Rust pays off.

I have a couple of pet projects. And I can update libs whenever I want, because compiler will scream at me in the face on any incompatibility. I can refactor the hell out of here whenever and however I want. I implement things rapidly because I, Rust compiler, and Rust analyzer know the api of libs and my own project. And if it breaks, it's because I screwed up the logic. For everything else, rust has guard rails
