I think a lot of our widely held cultural beliefs on this front have been informed by academic philosophy from the 60s, 70s, and 80s. In particular, I would go do far as to say that Hubert Dreyfus, author of the book "What computers can't do" and frequent friendly adversary of Daniel Dennett, has a lot of responsibility here. He is famous for claiming computers would never become competitive at chess because chess required "insight", and always differentiated computer capabilities from complex behavior or human-like behavior, because the latter had something special that could only be represented with vague and underdefined terms. Even now I think Dreyfus is approvingly cited, while his core thesis is getting closer to being refuted every day if it hasn't been already.
