Great video and questions. On the one hand I think that people can be too quick to dismiss the intelligence and complexity of insects. On the other hand I'm convinced that their experience of the world is radically different from our own. So, different analogies might fail.
Yet I think there is something like "frustration" in ants. Something builds up in an ant when she is trying to do a task and fails over & over. Something causes her to give up or change strategy.
