When Michael Abrash wrote his books, C compilers weren't known for the quality of their blazing machine code.
It also has a proven record that no matter what, exploits are bound to happen, making the whole industry turn into hardware memory tagging as the ultimate solution to fix C.
Memory exploits in Rust : Yes much less. That's where the world is (hopefully) headed to.
But then a lot of people would disagree on "Lets jump on the <new-hot-language> bandwagon ASAP". Even the transition to parts of Linux kernel components in Rust is slow and cautious. In that sense, C is still a wide choice. Plus there are a lot of people actively working on C. Rust is only but picking up. it's more likely people will write buggy code on a new language than something which has been around for a while.
