AI-assisted coding looks fastest when we stop the clock too early.
A model can scaffold a crate, implement a trait, generate tests, and reach a green cargo check before a human engineer has finished tracing the existing ownership model. That is a real capability. It is also a poor measure of completed engineering work.
Senior systems developers care about the rest of the path:
Is the ownership model intentional, or did the implementation clone its way out of a lifetime problem?
Is shared state necessary, and are lock scope and contention understood?
