Unsafe is not evil, however as far as teaching beginners what to stay away from until they know better, I can understand why people jokingly say that it is =) It's just a tool of course, so the perspective that it's neither bad nor good is justified to an extent. But it's not that unsafe is complicated, it's that it's full of unknown unknowns. If you don't know any better, it's _really_ easy to write something not exception-safe, accidentally trust safe code a little too much to maintain invariants in your in unsafe code, or to break some other subtle assumption that prevented LLVM from merrily miscompiling what's in your head.
