Rubinius is neat, but for me personally (and I think most of the community) it's performance. Writing C enables optimizations by hand that still yield very significant performance gains over the best of what any other high level language (java, c++, ruby) can muster. I don't want to write C, but I'm glad someone else does so I get the benefits when I write Ruby.

I don't understand how you can say Java, C++, and Ruby in the same breath. They are not at all alike. Also what optimizations are available to C which are not in C++? C++ is (almost) a strict superset of C.

  Just because C++ is a superset of C doesn't mean that all C++ features are in a way comparable to C (in compiling and at runtime).

  Restrict pointers in C let you write code that's faster than the C++ equivalent for functions that copy a lot of memory.
