I think there's room for two large open source C++ compilers (GCC and Clang), just as there's room for two large open source Web rendering engines (Gecko and WebKit), two large open source general-purpose scripting languages (Python and Ruby), two large open source statically typed VM languages (Java and Mono), three large open source desktop environments (Unity, GNOME, and KDE), etc. Why people think competition is a bad thing (e.g. "the Web should just be WebKit!") is beyond me.
