C++ has loads of inefficient abstracted programming models but rust doesn't? C++ has moved on from the days when that argument was made. This may have sufficed for an argument against C++ then but it should also apply to rust today which has similar infrastructure like generics and traits that allows a level of abstract programming that C doesn't provide.
