There are safer, better alternatives for almost everything we do. But economy dictates that we end up with a compromise. Rust would be just another compromise, slightly different stage, no huge difference and potentially a huge cost.
Silver bullets in software development do not exist, rust is no exception to this and the irrational hyping of rust as being a silver bullet actually has the opposite effect.
If rust is that much better at all aspects of software development (and not just in preventing one class of bugs) then it will find mainstream adoption. But you don't get that effect by ramming it down other people's throats, you get that effect by showing it in practice. And this is where rust - at least so far - is underwhelming.
Also, and this is another point of irritation with me, the rust community makes it seem as if theirs is the only language that will avoid this kind of bug, which is far from true, there are other platforms / languages with far wider adoption that have these traits as well.
