We also need to keep in mind that for a small segment of C++ 
programmers it is important to be able to use CPU/SoC/hardware 
vendor backed compilers so that they can ship optimized code the 
day a new CPU is available. So there is a distinct advantage 
there for people who don't aim for consumer CPUs.

Most programmers don't care as much, since adoption of new CPUs 
is slow enough for GCC/Clang to catch up in time.

Anyway, as C++ is taking more and more of C's niche, this issue 
can be more an more "threatening". E.g. hardware vendors that now 
only ship C compilers might in the future only  ship C++ 
compilers... I don't know exactly where this is going, but it is 
possible that C++ could become hard to displace for hardware 
oriented programming. Seems like more an more embedded 
programming is moving to C++ from C.
