I feel like I'm in the minority in not finding C++ complicated. C++ has gotten significantly LESS complicated c++11 and onward, I'd say. Inheritance hierarchies with private/protected/friends and virtual methods lead to significantly more complex codebases than flat templates and judicious use of constructors and destructors to handle things' lifetimes. When you've got a nice templated API, writing the client code almost feels like writing in a scripting language.

I'd say the only really hard part is understanding move semantics, but even then that's not really necessary and the verbiage on the internet is way too academic in that regard when it's really simpler in practice than it is when explained.
