But neither Zig nor Odin solve this problem. The only serious attempt is Rust.

Rust is super heavy handed in how it does it.

See. Rust fans are often naïve believers in silver bullet solutions.

Computer security and exploitation is a complex and difficult topic.

Bad actors are looking for vulnerabilities to build exploits, some are related to memory corruption but many of the most sophisticated ones are not.

All programs are potentially unsafe, regardless of the language. Using a language like Rust can help to some extent, but it won't be sufficient if the programmer is too ignorant about code hardening.

You can't replace experts with the flip of a switch.
