seems to me that one approach is fueled by data and the other is fueled by understanding. in the former, the observations form a view of behavior which is then modeled with high fidelity. in the latter, active inquiry, adversarial data collection and careful reasoning produce simpler models of hypothsized underlying processes that often prove to have nearly perfect generalization. the interesting future is probably the one where the former produces new building blocks for the latter. (ie, the computer generates new simple and easy to understand constructs from which it explains previously not understood or well modeled phenomena.)
