On the unproductiveness of language and linguistics

van der Velde & de Kamps (dvV&dK) present a response to Jackendoff's four challenges in terms of a computational model. This commentary supports the position that neural assemblies mediated by recurrence and delay indeed have sufficient theoretical power to deal with all four challenges. However, we question the specifics of the model proposed, in terms of both neurophysiological plausibility and computational complexity.
