Sure. SWE is not a first industry where you can get away with cutting corners or straight incompetence. And some people are going to write a code taking care of ownership by experience, skill, etc. and they don't need Rust. They might not know they are taking care of ownership, and yet do it correctly. Rust is only formalizing and verifying it.

I think in time more and more people and teams will discover that doing stuff with Rust is just cheaper and more productive. You learn ownership once, you get great results ever after.
