When I made a meme about C++ [1] I was purposeful in choosing the iceberg format. To me it's not quite satisfying to say that C++ is merely complex or vast. A more fitting word would be "arcane", "monumental" or "titanic" (get it?). There's a specific feeling you get when you're trying to understand what the hell is an xvalue, why std::move doesn't move or why std::remove doesn't remove.
The Forest Gump C++ is another meme that captures this feeling very well (not by me) [2].
What it comes down to is developer experience (DX), and C++ has a terrible one. Down to syntax and all the way up to package management a C++ developper feels stuck to a time before they were born. At least we have a lot of time to think about all that while our code compiles. But that might just be the price for all the power it gives you.
