I'll keep saying it: give me a modern language that is cross platform, results in reasonably sized code footprints, is fast, and that can be used to ship code on all the major OSes, and I'll switch. Until then C/C++ is the only way to achieve that.
It's analogous to the situation with JavaScript on the web. JavaScript is the language of the web because JavaScript is the language of the web. C/C++ is the language of systems because C/C++ is the language of systems.
