Then how do you explain the fact that some of the most secure pieces of software ever written were written in C? (I&#x27;m thinking of, e.g., Qmail — and pretty much everything else DJB has ever written — and OpenBSD, just to name a couple off the top of my head.)<p>I would also qualify your statement that &quot;performance is not everything&quot; to say that performance isn&#x27;t <i>always</i> everything. Writing a kernel in an interpreted language probably isn&#x27;t the best idea, for example.
