It would be silly if they were indistinguishable from human-created images, but they aren't, exhibiting the typical AI artifacts and weirdness, and thereby signal a lack of care/caring.
The human effort idea is even a bit morally objectionable. You can feel that you're worth more than others because more of the lives of others were consumed to create your possessions. It's a zero sum game where poor people can never afford high-care art because their time is worth less than the artist's.
