I would offer that it's not the algorithmic complexity, but the interconnections that are "interesting", and any (perceived) relationships in a block universe necessarily entail an observer. This is the "zen" running through Pirsig's book about the meaning of meaning.
Since Robert Pirsig put this very well, I’ll just copy down what he said. I don’t know if this story is based on reality or not, but either way, it’s true.
