That doesn't match my experience _at all_. Have you worked in C++ 
in a professional capacity?

C++ has a major version every 3 years, that comes with myriads of 
traps and new best practices.

The new stuff is non-breaking, except by living in that ecosystem 
you will inevitable be exposed to approximately all parts of the 
language. That's a huge mental load to spend.

Last time I touched C++ (2015) people were _in some companies_ 
starting to use C++11 (30% of it), because the compilers are 
necessarily lagging behind the C++ comittee.

Who said C++ was hard to learn/teach?
