I compared stone soup to AI before, but for very different reasons. That is, you cannot convince the villagers to contribute their data/food by appealing to them; rather, you have to trick them into giving up their data/food. But the result is bigger than the sum of its parts, including the villagers (if they are willing to drink the soup). IRL, the trick is ToSes and pro-AI laws. Meanwhile, some villagers may be willing to contribute in the first place: those will be free culture advocates, public domain advocates, pirates, etc.
