I'm not an expert in anything relevant to this, so this is ill-informed speculation. But isn't referring to not knowing "the weights" (as the article and researchers do) making a rather large assumption about the nature of the problem? It sounds more like the researchers don't know "why the neurons fire when they do", which would leave open the question of whether "weights" is even a sufficient model.
