Bluntly: exactly why does Ada matter, at all? The code footprint of software (1) written in Ada and (2) of concern when we talk about memory safety has measure zero. Is Ada better than C++? It turns out, I don't have to care: to go from C++ to Ada, one needs to rewrite, and if one is going to rewrite for memory safety, they're not going to rewrite to Ada.
