As the foundational figure in modern Linguistics Chomsky has had an outsized role in shaping the field, some of it good and some bad. IMHO the usefulness of mainstream generative grammar has waned since the 70s or so in terms of its applicability to engineering and empirical rigor. But it remains dominant, in part due to his influence and the logical conclusions one draws from a strong interpretation of Universal Grammar. Since much of that foundation is ultimately philosophical, there are bound to be challenges from the field now and again, and acolytes of the Chomskyan school are likely to attack them ferociously. It will probably be a few decades before there's a major shift.
