Even the modernest pointers unique_ptr and shared_ptr are dangerous (use after free/move and, e.g., ease of data-racing in the data, respectively). The problems with them are relatively fundamental to C++ and its idioms. The classes you define will need to avoid using fundamental C++ features like references too: anything pointer-like can lead to problems (including `this`) The "you (and the standard library, including the completely new parts) are holding it wrong" defence is tired, when it is so ridiculously easy to do so: it is okay and important to acknowledge that a tool is powerful but also has a pile of hard-to-avoid sharp edges.
