As the intro page demonstrates, modern C++ isn't really all that messy. I think there's a solid argument that it's a more dependable option than Dart, which isn't really used by anyone other than Google.
Better languages have moved beyond C++. I've developed software for over 20 years. I've use C++ for many of those years. Software languages and tools have evolved past C++.
Imagine the "evolution of man" drawing. C++ is the middle guy not exactly standing upright.
An "evolution of man" drawing wouldn't really be accurate because it implies each entry is static in terms of evolution. C++ is very obviously not, and modern C++ is barely recognizable compared to code written years ago.
