What's the underlying structure that leads to the complex behaviour? It's not asking about the motivation for the form, it's asking about the properties of the structure. With scissors neither the mechanism or the behaviour is particularly complex, so actually understanding what's going on isn't too much of a struggle. With deep-ML you're dealing with a very large number of entanglements of increasingly abstract and opaque higher dimensional concepts or notions (depending on how much you want to anthropomorphise the machine).
