Rust’s borrow system is actually not the key part; if it were just that, then yes, it would be purely a complication performance would be the only important part about it when comparing it with garbage collection. No: the key part is the ownership model, that an object is owned in precisely one location. Borrowing sits on top of and fits into that, not the other way round.
The ownership model is the part that I don't myself yearning for in other languages I work in such as Python and JavaScript.
