I think we'll have flying cars before we have to start focusing on compiler bugs. Most software is already written in memory safe languages and their vulnerabilities are unrelated to memory safety, they're just plain old logic bugs.
No, you are wrong. Rust compiler bug uncovered this month was aboıt memory safety: https://www.penligent.ai/hackinglabs/rust-borrow-checker-bug....
Basically, the borrow checker allowed writing memory unsafe programs without using the keyword unsafe.
Compilers for C, C++ etc. are well established but Rust is a relatively new language. There are many bugs to come just like this.
Using a memory safe language is not a silver bullet for writing memory safe code. The implementation of the memory safe language introduces bugs as well.
You misunderstood, I'm not saying that compiler bugs don't exist or that they're unrelated to memory safety.
I'm saying that these compiler bugs are extremely low on our list of priorities. If we want to eliminate all vulnerabilities in all of software we have about a century worth of logic bugs that are likely more critical and easily exploitable than compiler bugs.
