It's still in early development, but there is a tool[1] that automatically converts potentially unsafe C/C++ code to be memory-safe. If the problem is C/C++ programmers that write unsafe code, rather than trying to change their practices (or even change the language they program in) maybe it's more practical to just have a robot "fix" the code.
