This may not invalidate your point, but C++11 was a major step forward that, for me, made C++ feel much more convenient and modern than before. And C++14 is basically just adding/fixing stuff that should have been in C++11 in the first place.
I’m a “traveling programmer” in Korea. But when I go out to a work site because they say I have to work on C++, as you know, there are so many versions that it’s painful.
