So what does he mean by public? It seems to me that he is essentially saying because he can see it publicly I can use it to train anything without caring about the license? Based on his assertion, can I take a copy of windows (or github for that matter) and train an ML on it to replicate its behavior (assuming I have such a powerful AI)? It seems to me that is essentially what follows. In fact I'd argue that this is more akin to clean-room reverse engineering. It also seems to fly in the face of case law for using soundsnippets in songs. Isn't what the model is doing really just a sophisticated algorithmic rearrangement of samples?
