I had a very different reaction. I had the sense this was an art world person (student or otherwise) who wasn’t technical enough to make it interesting. Many computer generated art projects are much more dynamic and produce much more passable art (https://ml.berkeley.edu/blog/posts/clip-art/). That said, I think I would have to agree with other comments here, I don’t think any deep conclusions could be drawn from these results. For starters the artworks are really repetitive and i would guess it biases respondents quickly toward the negative.

Is it?

This page just confirms the above poster's hunch. A professor of mathematics who teaches one "Mathematical Design 128" class.

As linked on that page, he is an artist as well: https://christopherhanusa.com/

I don't know how "technical" or "emotional" that is, but it's certainly art.
