Exactly. It actually is a cute art project and I quite like seeing their in game perceptron running, but if it were presented as a serious argument then it’s just an appeal to absurdity that rejects the notion of substrate independence. It’s trying to get the reader to reject the premise on the basis of a gut feeling of what a game is, the gut feeling of course hides that it’s just another way to do computation. But I guess that’s the point.
