I agree with you, and think that people are overplaying the AI hype. People think that training an AI is like training a human, and that’s not really true.
But even if it were, what this guy is doing with his AI goes beyond that. I think anyone would agree that there is nothing preventing a new comedian from binging on all the George Carlin material, then making their own show, under their own name . But if that human literally put on a George Carlin mask and billed their show as “George Carlin”, his estate would (rightfully) get upset, even though everyone understands this can’t be the real George Carlin. Why should this guy get a pass just because he had an AI do all the hard work of writing the jokes?
