The original comment to rewrite VLC in rust was mostly sarcasm. Sure, if every app and library was rewritten in rust without using the unsafe features, we'd see a lot fewer of these kinds of bugs. But it's going to be a long long time before we live in that kind of world. That doesn't mean people can't start today - imagine if the top 5 codecs were written in a safe language, then they could warn users about "less safe" content for anything else without pissing off too many users. Maybe. And that alone is a big job.
