True. So true.

The thing is c++ is a vast massive monster. Most likely whoever deeply worked on it, knows there's so much stuff left to learn, and so many deep dives, that whoever claims expertise is likely to be a newbie who hasn't been close enough to the edge to see what's ahead.

I remember once, spending like a couple full days along with a graphics researcher, who worked on that stuff full time, trying to get to work some rendering done with OpenGL on c++ which just didn't behave when compiled in MSBuild. Only on MSBuild. We found way later the solution from a guy in a forum, which was hacking the opengl implementation , overriding some macros ,and doing some other obscure thing on the library as well.

Even today we're both baffled at how that dude came up with that hack.
