I am not saying C++ and all the stuff listed is always safe, just that it's good enough for daily use, including professional use where lives are on the line. As I said before, you used extreme words and made C++ sound like Java applets - something no one ever should use nowdays outside of truly exceptional circumstances (a.k.a. not something as widely used as OSes, browser and the HotSpot JVM). I'm sure you have seen BS codebases in Java, C#, PHP, Python, etc. as well, I've seen weird interactions with GC in WildFly (I can't comment more because I'm not a Java programmer), spooky action at a distance, globals, using one huge table in a DB to store everything thus missing the point of a relational DB, etc. all in non C nor C++ and it'd not help these things if they were in Rust. Not all bugs come from the language itself either, some are just true programmer errors. I just google for PHP SQL tutorial (not an English one) and the result is of course pasting input together with SQL to form a query, 0 escaping... Sony had a leak like that. Many Windows issues are pure ignorance like having SMB (that turned out to be buggy, but still) running by default, similarly stuff like misconfiguration, default passwords, Apple's goto fail won't be solved if people are copy pasting code and formatting it badly (unless Rust enforces that, I'm not sure, I don't know Rust yet). Rust will not prevent these kinds of mistakes (maybe the last one if the compiler itself detect inaccessible code and maaybe the SQL one if it marks the variable from user input unsafe at first and cascades that through the function calls to see if it was pasted and passed to SQL) unless it has extremely deep understanding of what's going on. Additionally, despite all the bugs in Windows there (sadly) wasn't a huge exodus to Linux (which too has tons of bugs and is in C and has lots of programs in C++), it just works "well enough" despite the flaws, there no disaster hanging over our heads.
