I have to write a critic to this paper:
"Intention Is Choice with Commitment" by Philip R. Cohen and Hector J. Levesque
There is this one passage I definitively do not understand, right at the beginning:
Some time in the not-so-distant future, you are having trouble with your new household robot. You say "Willie, bring me a beer." The robot replies "OK, boss." Twenty minutes later, you screech "Willie, why didn't you bring that beer?" It answers "Well, I intended to get you the beer, but I decided to do something else." Miffed, you send the wise guy back to the manufacturer, complaining about a lack of commitment. After retrofitting, Willie is returned, marked "Model C: The Committed Assistant." Again, you ask Willie to bring a beer. Again, it accedes, replying "Sure thing." Then you ask: "What kind did you buy?" It answers: "Genessee." You say "Never mind." One minute later, Willie trundles over with a Genessee in its gripper. This time, you angrily return Willie for overcommitment.
The problem is, that I do not understand why Cohen and Levesque speak of overcommitment. Genesee is an existing beer-brand (I googled it), and the rest seems clear to me: A man tells his robot to bring him a beer, and the robot does that.
Why is this overcommitment? I think I miss out on something important here.
