Exactly. Compiler-enforced ownership and lifetimes _dramatically_ reduces the mental overhead of memory management compared to C. It also saves time from having to run things under Valgrind and ASAN just to make sure I didn't mess up. The extra time spent getting Rust code to compile is considerably shorter than the time required to debug something Valgrind found.

I feel the same way about C++ smart pointers, which are remarkably simple to use and understand.

While definitely an improvement over raw pointers, ultimately C++'s smart pointers still fall short in several ways: they can be null, there's no lifetime checking for references (so you can still use after free), there's no object freezing (so you can still have data races), etc.
