I think the effort is indeed a big piece of it. For example, consider sports. I don't imagine that a lot of sports fans would be interested in watching completely AI-generated video of their favorite teams playing, even if it's totally believable. Surely the main point of the whole thing has something to do with humans at the top of their skill, measuring up against each other, and experiencing it together with them?

For me it's the same with music. I am sure I will be fooled by some AI generated music now and then, but what does that prove?
