On "Scripting" Languages:
The nice thing about saying "nobody has ever written a reliable, high-performance program" in a so-called scripting language is the person saying it controls the debate. If you point one out, he can claim that such and such a program isn't reliable enough or doesn't exhibit high enough performance.
Remember folks, it's not the experience, skill, dedication, talent, or luck of your developers, it's whether you choose a language that forces a dedicated compilation stage... at least if you're poisoning the well.
