I think they were hoping to lean into the uncanny valley of AI art to cause a sense of imbalance/discomfort to fit the whole secret invasion theme. And of course save a boatload of money along the way.

I’m not necessarily against it as a concept 'cause I think art will survive AI as it survived digital painting, photography, and loads of other revolutions before. But it really is kind of a slap in the face to the artists that got Marvel where it is today.
