Rust is an unergonomic language that slows development in the general case (because it has lots of arcane syntax and rules, and people generally don't know it). Suggesting it as the "obvious" choice ignores the tradeoffs that come with adopting it for a project.
You can just hire people who know Rust. One Rust developer would likely end up more productive than ten Cursor baby sitters in the long run, and you would actually get a high quality app.
