It's possible to predict the behavior of black boxes without knowing anything about their internal structure.

Elaborate?

That says a lot more about your personal values then the general human condition.

I suppose you are right.

The models of worms might be a bit better at predicting worm behavior but they are not perfect.

They are significantly closer to being perfect than our models of humans. I think you are right in pointing out that where you draw the line is somewhat arbitrary. But the point is the variation on the continuum.
