It creates useful Go knowledge. What else could be asked of it?

[TaupeRanger]

No it doesn't. Human Go players got worse after playing it. No one learned anything useful. The "knowledge" (if you can call it that) is all contained in an abstract, uninterpretable form that is of no use to anyone.

Who got worse, and how? Seems like a pretty unlikely claim to me on the face of it.
