Not just. Humans invented the styles that DALL-E is using in the first place. The emergence of these novel styles isn't just interpolation. DALL-E, while incredible, seems stuck within the scope of these styles.
When we evaluate the pupils in the end, we have this dry conversation - did we bring up any geniuses? Are they just interpolating between different styles that they have learned?
I think that in the case of the 30 pupils we would say that they have creativity, ingenuity, showing signs of thinking for themselves. It would not be as ambiguous as it is with Dall-E2's art.
