Maybe it's because I think your comment throws away a lot of relevant context from OP's submission on HN.

He says he spent months on this piece and then some, I think it's safe to assume here that this was well supervised, guided, thoughtful and full of human intent despite the AI-assisted part.

In short, I think calling it "AI generated" takes all the human effort that went into these months and the ingenious creativity of OP towards crafting this piece!

Anyways, I enjoyed it. :)
