That perspective is blown to those that see beyond themselves.

Or can admit themselves as fallible.

Or realize that even if they are near-infallible, that unless they've studied the C _and_ C++ standards to the finest detail they will probably unintentionally produce code at some point that the modern C++ compilers will manage to make vulnerable in the name of undefined behaviors optimizations (see the recent HN article about how modern C/C++ compilers has a tendency to turn fixed-time multiplications into variable time and vulnerable to timing attacks).

But of course, there is always tons of people that believe that they are better than the "average schmuck" and never produce vulnerable code.
