Possibly. Depends on the quality of the reviewer and the complexity of the code (as a whole). On average Rust programmers aren't necessarily better than programmers using any other language. If history is a guide then if Rust takes off there will be plenty of terrible, buggy, unsafe and very thoroughly reviewed Rust code out there used in popular, widely used applications or services.

I find the notion that "explicit unsafe makes bugs less likely" to be suspect. It seems reasonable, almost tautological at first glance. But theory and practice are different animals.
