Smart pointers aren't the beginning and end of things. C++ is riddled with places that can be converted into weird machines, even if you guarantee correct lifetimes of everything on the heap. Look at how much fun we can just have with the stack! std::string_view foo(std::string_view s) { return s; } auto s = foo("temporary"); // kaboom Modern C++ does not force you to initialize everything before it is read. Modern C++ happily lets you ignore bounds checks with vector operator[] or by using c style arrays or by doing pointer arithmetic. Modern C++ happily lets you overflow integers or silently truncate when widths change. And on and on and on. Turning every "new" into "make_shared" is nowhere close to enough to make C++ safe in the face of bugs.
