It is impossible to determine whether something was well-designed without speculating as to its intended function. Bombs are machines, machines whose function is to fly apart; they generally do not last particularly long when they are used. Does that make them poorly-made?

If the purpose of a collection of gears was to fly apart and transmit force that way, sticking together would be a sign of bad design. Saying that the gears must have been well-designed *because* they stick together is speculating as to their intended function.

I do not see what is gained by labeling blind entropy-increasing processes as 'intelligence', nor do I see any way in which we can magically infer quality design without having criteria by which to judge configurations.
