I'd say making buffer overflow and UAF CVEs Just Go Away -- forever -- is a DAMN good reason to switch to Rust.

I've found that prior exposure to C is somewhat negatively correlated with willingness to grok Rust. Something in their mind rebels against it, which is why I say that if you're an "old hand" C programmer who feels that the syntax of Rust is too hard, or the borrow checker is obscure, maybe you shouldn't worry about learining Rust because Rust isn't for you -- it's for your replacement. You're John Henry, the borrow checker is the mechanical spike driver, and no matter how hard you work at it all your programming discipline is just no match.
