FWIW this is my own mental gymnastics around the Chinese Room; at some point the question "where is the understanding?" is moot, because if the Chinese Room reliably delivers context-specific correct results in unique contexts, then what more do we require of intelligence? I have to admit that sometimes it does better than I can do, and I've been called intelligent by intelligent people my whole life.
(BTW Killing Me Softly wasn't written/sung/anything by Carly Simon, but composed by Charles Fox with lyrics by Norman Gimbel, in collaboration with Lori Lieberman [after she was inspired by a Don McLean performance in late 1971].)
