Who said anything about interpreted languages?

Modula-2, Modula-3, Go, D, Haskell, OCaml, Oberon, Ada, Extended Pascal, Object Pascal, C#, Java, ...

The list of languages with native code compilers is quite big, no need for interpreters.

The problem with fuzzing is that, like the use of safer languages, it just won't get adopted unless forced down the throat of developers.

This is why, Google, Microsoft and now Apple are adopting a "our way or the high way" in memory safe languages for their platforms. After all, proprietary APIs would already be enough for platform lockin.

I do agree no one is going to re-write the huge amount of code out there. However it is already good enough if new code get written into something else.
