Though I disagree with most of the conclusions in that essay, and in particular the expectation that Lisp (or a direct descendant) is going to be the language of the future, I still think it's way too early to call the above languages failures, even in the "Grahammiam" sense.
Python and Ruby especially are growing in popularity, and I think it's awfully premature to consider them evolutionary dead ends at this stage in the game.
I don't necessarily agree that those languages are dead either. I was just clarifying the point I thought he was trying to make. Plus I wanted to turn pg into an adjective :)
