It is clear that the way things are going, even the most passionate C++ developers can't make use of the language in a full safe way, understand the changes between revisions, and naturally Scott Meyers can't write books forever.
I certainly wouldn't manage a C++ interview quizz, even though I try to keep up with it.
The university where I studied during the 1990's, C was already on the way out.
First year students got Pascal and C++ with proper set of vector, string and other common data structures. This was a couple of years before C++98.
All data structures used bounds checking, and it was great, because the professor has a similar point of view as I, so C++ was taught as a kind of poor man's Ada in regards to safe coding.
What about C? Well, those taking OS classes were expected to be able to dive into it from C++ point of view.
However, this isn't normal, most institutes follow the more traditional path of C with classes, and most of them, hardly moved beyond C++98 anyway.
