I don't think Rust is the evolution of C. Its a nice thought, just like I like to think im the evolution of [famous well known person].

C++ was the evolution of C and so was Java, but they both turned out to be their own things and C kept on chugging. Rust is a big complicated language, there is nothing C like about it. I see more parallels between Rust and C++ than I do Rust and C.
