From bookfrag.com: Forget post-literacy. I prefer post-complexity. (Ah, but for a niggling doubt.)

Perhaps only once, on one blue planet, consciousness may emerge. Why? Was it worth the trouble? In any system, growing in complexity, falling apart as it must, there is a moment of emergence, maintained only by increasing energy and work. Is it worth it? I confess that I find consciousness, if nothing else, irresistibly interesting.
