> for example, to know that "he went through the door" means that "he's not in the room any more" > sure, the computer is able to recognize a bottle on a table, but doesn't have an internal representation of the 3D world that would tell him that glass bottle ... should be handled carefully (as it can break, as opposed to e.g. a ball) To be fair, these are also true of human beings in the early stages of their development (object persistence; the cry of "oh dear" that every parent of a toddler comes to dread).
