Yeah, the human ones are because we're talking finding a human answer to a human question.
It's possible has been trained to match a human level of assessment (though imo it's still a ways off) but the AI response is never going to be more representative of true understanding than a human response when it comes to a human question expecting a human answer.
It's quite likely that a given AI will have a more representative response than a given human - but we haven't ever tried to pump so many resources into the training of a single human scholar.
