I kind of think that as proof-of-concepts, the AI models are kind of interesting. I don't like the content they produce much, because it is just so utterly same-y, so I haven't yet seen anything that made me go "wow, that's amazing". But the actual architecture behind them is pretty cool.

But at this point, they've gone beyond researching an interesting idea into full on commercial enterprises. If we don't have an effective means of retraining the existing models to remove the data that isn't licenced for commercial use (which is most of it), then it seems the only ethical way to move forward would be to start again with more selective training data, including only what is commercially licenced. Now the research has been done in how to create these models, it should be quicker to build new ones with more ethically sourced training data.
