I don't know what to tell you. It's more than a little absurd to make the qualification of being able to do something to be that the output has to be considered a great work of art for generations.

I agree that the argument starts from a reduction to the absurd.

So at least we can agree that AI hasn't mastered the text medium, without further qualification?

And what about my argument, further qualified, which is that I don't think it could even write as well as a good professional writer - not necessarily a generational one?
