My exact thought process on seeing the title here: "Ah, 'insufficient data for meaningful answer'. No, wait, that one's called 'The Last Question'. So perhaps it's 'There is now'." :-)

(Asimov's is better. Also, the version of this one in my memory is better than the actual story, in that "There is now" is better than the rather clunky equivalent in the story. I suppose it's possible that I'm remembering a different, slightly better written, story with the exact same idea.)
