Linux

The un along with other governments are requiring all software including open source to be validated by a 3rd party security audit, C is notorious for its memory leaks and so switching to Rust is almost legally mandated but C is the foundation of modern society and switching will literally require rewriting linux from the ground up since Rust didn’t exist when it was made needles to say developers are not happy having to essentially learn a new language and start from scratch only harder because they can’t change anything they just need to rewrite it in another language and get nothing in return but happy bureaucrats as happy as bureaucrats can be anyway.
