> However, the mental cost a Rust programmer pays for that trade (due to borrow checker) seems too high for me In C++ land, you'd have to use TSan thread sanitizer and a lot of other tooling (ASan, Valgrind, etc) to achieve even close to the same level of confidence. Not only is this a runtime check but all that tooling has a fairly heavy mental cost too.
