100% agree. We had a C++ service that made heavy use of libcurl. A particular release of libcurl introduced some memory safety problems that caused frequent segfaults for us. These memory safety bugs were eventually fixed in another release, but it scared us enough that we investigated rewriting the service in Rust.

After successful experimentation with some prototypes, we eventually rewrote the service in Rust, auditing the unsafe code in our dependencies (of which there was very little). No segfaults ever since.

Side benefit: Since Rust networking libraries tend to have strong async support, and since some of our C++ libraries performed synchronous networking operations, we saw a big improvement in performance. The number of threads needed dropped by 5x.
