Rust just exposes the complexity an equivalent program in C leaves you to find at runtime. It doesn't have to prevent every bug, just substantially more than the languages it might replace.

You can write simple or complex code in any language.

The Obfuscated C contests exist so I really don't see what points you think you're making.

Some people have fun pushing their tools to their limits. That doesn't mean they do the same thing in production code.

Rust is a very obvious security win.
