That's an other problem, not technical but educational. A lot of (older) programmer came to C++ passing by C and continue to use C in C++.

That need time, education and guidelines to change that... a lot of time.

Changing mindset and programmer education is sometimes harder than changing the program itself.

> Now you just need to convince a large spectrum of companies to actually stop doing C idioms while writing C++ code.

That is already ongoing. However do not forget that C++ has a bagage of 25 years of code pre-C++11 to upgrade before arriving there.

While I mostly agree, plenty of companies aren't going to change their coding, and outsourcing practices, until they hurt their button line.
