As someone who never liked writing anything C++ since 2000+ (did like it before) I cannot agree with this. C++ and Rust are not comparable in this sense at all.
One can argue Rust is what C++ wanted to be maybe. But C++ as it is now is anything but clean and clear.
I think the comparison is fair, strictly in the sense that both Rust and C++ are designed around extensible programming via a sort of subtyping (C++ classes, Rust traits), and similar resource management patterns (ownership, RAII), where Zig and C do not have anything comparable.
See my other comment[1]
It replaces C++ for me, so I would say it's "a C++"
