Does an amoeba have an understanding of "food" when it makes an
association between the relevant chemotactic signals and the feeling
it gets when it engulfs the morsel? You might say "no, the amoeba and
this behaviour is too simple". Yet it's from compounding such simple
behaviours that we get human level intelligence. The computer
behaviour you described is even simpler than that of the amoeba, so
you would have to grant the amoeba understanding before considering
the possibility that the computer has understanding.
