You're not correct about AIs in general. Both chat LLM models and sentence embeddings can handle negation just fine. (Ask any chat "what clothes would a person wear if they weren't wearing a hat") Here it was simply not trained for that purpose. Maybe it wasn't worth it, maybe the creators thought that the negative prompt is enough, maybe the time was better spent on other examples. They way, it's not AIs in general, and it's not a tech limitation.
