Yeah, it's kind of a shame in this case. There's tons to talk about in the area of where Rust shines here ("makes concurrency easy", "provides easy access to fast algorithm libraries", etc.) but security is just not really one of those points.
I don't disagree. I am just happy to point out that Rust increases security (since most security vulnerabilities I see reported are buffer over/under-flows or other memory safety mishaps). Rust definitely does not solve everything in security. You can still open yourself up for an elementary replay attack if you're not careful -- like I did just a few days ago.
