"It seems...that the Aryan Model is being maintained very largely by its own tradition and academic inertia. Neither of these forces should be underestimated; nevertheless, they have been considerably weakened by a number of startling internal developments – all of which show that the Bronze Age civilizations were much more advanced and cosmopolitan than had been thought, and that in general the ancient records are more reliable than more recent reconstructions. Given these externalist and internalist contexts, I am convinced that even the Broad Aryan Model is untenable and that the Ancient Model will be restored at some point in the early 21st century."
