Super sane choice, C has had its time, Rust is an improvement over C++, but lacks higher kinded types and other niceties that are easy to implement in C++. C++ is also used in a large number of projects that fuchsia needs to interface with, such as skia, the graphics stack and so on. This is one of fuchsias competitive advantages. Moreover FIDL (fuchsia interface description language) allows for components to be implemented in a number of other languages.
