For a web backend? Rust is pretty mature there, it doesn't even feel like an innovation token - it's by my favorite thing to use Rust for.

You have very mature webservers, asyncio, ORMs, auth, etc., it's very easy to write, and the type safety helps a ton.

In 2020 it might have taken some innovation tokens, but the only things that require a ton less (for web backend) are probably Java, python, and node.js, and they all have their unique pain points that it doesn't seem at all crazy?
