Does it show how far AI has come? It produces a game that is fundamentally unplayable, and because it's purely based on a model of language doesn't have a very obvious path to improve, since there's no underlying model of the thing it's trying to represent.

Are any of these applications of GPT-2 that attempt to use a pure language representation as a way to sidestep modelling the underlying principles actually successful? I feel like I've not actually seen any real successes.
