The memory safety track records of large-scale software written in modern C++ disagree with you. I don't think this is a tenable argument.
C++11 and C++14 don't really add any memory safety features over C++03 plus user-defined reference counted smart pointers. In fact, I think there's a reasonable argument to be made that C++11 is less safe in practice than this use of C++03. If you use rvalue references and move semantics a lot (since "use-after-move" is now a very real problem), or if you use lambdas a lot (since it's so easy to make dangling upvar references).
