"As someone who works on child language disorders, I have tried many times to read Chomsky in order to appreciate the insights that he is so often credited with. I regret to say that, over the years, I have come to the conclusion that, far from enhancing our understanding of language acquisition, his ideas have led to stagnation, as linguists have gone through increasingly uncomfortable contortions to relate facts about children’s language to his theories."
