I am not the last Hispanist, ni mucho menos. Hispanism will survive me, for sure. Yet I note that my own field, the study of Spanish poetry, is in decline. Very few of us do it any more. Latin Americanists have abandoned the study of poetry as well, and I am the last poetry specialist in my department. It isn't likely that a poetry specialist who retires will be replace by another poetry specialist.
The same could be said for drama, and even narrative. It is fine for the field to reconfigure itself, but I wonder whether we will have people like me in the next generation.
