I think after a while writing the language, you're able to reason about your object memory with little friction from the compiler. On the Rust-written projects that I work on, I rarely have significant compiler errors that impede on my efficiency in adding new features. After a while, you know that you're mutably borrowing something, or that you're crossing a thread boundary and are carrying something not thread-safe along. Maybe like other low-level languages there's a large learning cost, but it gets better after a while.
