I would say that perfect encryption is a great example of something we don’t understand which looks like noise: at first it looks totally random, but if someone hands you a short key, suddenly it becomes obvious that the “noise” is highly systematic. That’s understanding. The problem is that achieving understanding is not always computationally tractable.
