Why not? If a hypothetical AI had a world model as sophisticated as that of a real person and had complete understanding of human sensory and emotional processing, what exactly would preclude it from making such an art piece?

Of course, current AI can't even make an 8th grader's essay (which is not to say that it isn't impressive). But what these artists did was not magic. As far as we can tell, the brain is a purely physical entity. Unless you believe in dualism, which would be fair enough, there is no reason to suppose that what we do could not be replicated by something "artificial".
