When someone writes about the end of the Von Neumann architecture, I take it as dreaming that the poster's favorite language will someday be faster than C.
"You do realize that John von Neumann spent the last 10 years of his life singlehandedly developing a theory of computing based on cellular automata? The computer you're reading this blog rant on was his frigging prototype! He was going to throw it out and make a better one! And then he died of cancer, just like my brother Dave did, just like so many people with so much more to give and so much more life to live. And we're not making headway on cancer, either, because our computers and languages are such miserable crap."
