Because AI "art" being posted around isn't even consistent throughout the panel, and is often devoid of effort and context so even when it's not that interesting, it's not even pleasant to look at.
Comic artist like C&H and Oatmeal, while having terrible art, at least are funny and with context. There's human in it, and they can call the style their "own", even if it's stick figure it's stick figure with distinction. AI art just make you think "is this made from AI?"
You want people to appreciate AI comic? Sure, do the touch up first and make everything consistent.
