Bjarne took the wonderful thing that was C and made C++. Rob is not a fan of C++: he thinks the language evolved badly and added poor concepts from the beginning (IIRC iostreams and templates were two of the concepts), and it embedded a number of design decisions that led to extremely slow compiles and links (like, 45 minutes to link a Google binary). Ian Taylor even wrote a better linker (gold) for Google to deal with that.
