So many memory corruption issues, I'd like to think in 5/10 years time this would be solved and everything written in a safe language but maybe I'm being optimistic.
Now, we've got languages like Rust that offer improved safety mechanisms without really sacrificing expressiveness or runtime performance the way "managed" languages do, so there's a real alternative for software that needs the highest performance or best battery life.
If you mean safe like there's no way a programer can screw this (100% memory managed like JavaScript, Python, Ruby) than I'd bet not.
