It is fascinating how despite the thousands and thousands of high profile memory related RCE vulnerabilities, how this community doesn't seem to like pointing the fact that C is an unsafe language.
Rust is only “safe” because by default you’re not allowed to do certain things. If you applied those same limitations to C it would be just as if not more safe. And the things you’re not allowed to do in “safe” Rust is required in various applications that C excels at, meaning that for Rust to do the same it has to be “unsafe”.
Nobody has ever denied that unsafe Rust code exists, so I don't know why people keep acting like it's some gotcha that invalidates the value of Rust. The point is that in Rust, it is clearly delimited where those unsafe operations are occurring, so you can focus on making sure those specific parts of your code are solid. In C, you have to be vigilant about your entire code base, not just a handful of blocks. Moreover, most Rust programs don't need to use unsafe at all, so those authors can rest easier.
